MS6/MZ6 Front Camber Arms

We are happy to announce the return of the CorkSport Adjustable Front Upper Control Arms for Mazdaspeed 6 and GEN1 Mazda 6 to complement the return of the CorkSport Adjustable Rear Camber Arms. Back and better than ever, the CS control arms provide improved handling and easier wheel fitment through front camber adjustability. An impressive 4.5 degree adjustment range ensures you are able to get the camber you want. Whether you are dialing in your handling for the track, correcting your added camber from lowering, or even just adding in more camber for that new wheel and tire setup, the CS adjustable control arms are a good fit for your build.

CorkSport Adjustable Front Upper Control Arms for Mazdaspeed 6 and Mazda 6

The focus of the CorkSport Adjustable Control Arms is an easy modification of the OEM camber setting. You only need to jack up your car to easily access the four bolts on top of the control arm. Once loosened you can adjust as needed before tightening everything back up and lowering your car, without even removing a wheel! It’s a great setup for correcting camber from pothole damage or lowering, optimizing your alignment for the track, or adding negative camber to get the stance you want to fit that new wide wheel setup.

Modify your Camber setting without needing to remove your wheel!

At CorkSport lowering spring height (1.5” lower than OEM), our local race alignment shop measured an adjustment range of approximately +0.5° to -4.0°. During the measurements they even complimented how easy the CS arms are to adjust! If you’re lower than CS spring height, you are able to go even more negative due to the natural camber gain of the MS6 double wishbone front suspension. While if you are higher than CS springs, you won’t be able to go as negative.

Truly an easy bolt-in installation with no strange handling geometry changes

Because the CorkSport upper control arms replace the entire OEM upper control arms, we knew that fitment was vital to ensure correct handling characteristics, and an easy installation. These arms were designed directly from the OEM control arms so they are truly an easy bolt-in installation with no strange handling geometry changes. With the added camber adjustment, we also verified clearance throughout the suspension travel and at all camber settings to prevent any strange noises or damage to your vehicle.

Long lasting strength for your Mazdaspeed6

We have put the CS adjustable front camber arms through extensive real-world testing to ensure long lasting strength for your car. We have been testing an early production unit on a MS6 for around 6 months at the time of writing. This car has been used in everything from daily driving, to aggressive driving in the twisties, to even hauling heavy loads around. Throughout all of this, the car has been setup with -3° of camber with a 255/40-18 summer tire on a 9.5” wide wheel.  We have seen consistent performance out of the CS control arms with no issues whatsoever, so you can be sure they can take whatever you can throw at them!

CorkSport Adjustable Front Upper Control Arms for Mazdaspeed 6 and Mazda 6

Each set of CorkSport Adjustable Control Arms is made from A513 steel for long lasting strength and durability. The camber adjustment box on the arms are gusseted for added strength and rigidity. The arms are then finished off with a black powdercoated finish for long lasting corrosion protection and a great look. Each kit also comes with brand new ball joints, castle nuts, and cotter pins to keep everything operating correctly. Plus, we upgraded the rubber bushings where the arms mount to the chassis to spherical bearings. This change ensures good consistent handling feel and reduces slop that can result from old worn out rubber.

Auxiliary Fuel Tank

Mazdaspeed 3 Auxiliary Fuel Tank

Mazdaspeed 3 Auxiliary Fuel Tank

The time has come to reveal our Speed 3 Auxiliary Fuel Tank design!

Years ago there was an option to run Port Injection or Methanol Injection without the requirement of a smelly and messy tank in your cabin.  Sadly that option disappeared and left the community with a need for another purpose-built and designed option for high power Mazdaspeed 3s.

That’s right! There is soon to be another fender mounting fuel cell for the 2007-2013 Mazdaspeed 3 and it’s packed with more capacity, durability, and functionality.  

We approached this project with a clean slate and set a goal to maximize capacity, work with both GEN1 & GEN2 Mazdaspeed 3s, and provide the functionality needed for both methanol and E85 port injection auxiliary fueling.  

This was no easy task; we encountered many challenges that forced us to look to different methods and innovations to succeed.  However, through those challenges we developed a tank like no other available for the Mazdaspeed community.  

Mazdaspeed 3 Auxiliary Fuel Tank

The greatest challenge we faced was the manufacturing method.  We originally approached the design with the intent to use cut, formed and welded sheet metal as the material, but this quickly proved to create many unwanted issues.  Cost, design flexibility, capacity, durability are just a few of the issue we faced with sheet metal.  With that we looked to other processes…what about a gas can?  Those are plastic and have very irregular shapes…

From there we identified that rotomolding was the ideal path to pursue.  It helped us maximize capacity, incorporate the features needed, reduced cost, and increased durability/reliability of the tank. 

Speaking of durability first…

Mazdaspeed 3 Auxiliary Fuel Tank

Yup…we parked a truck on the tank and it took it like a champ.  As you can see there is a small amount of deformation, but that’s it!  After that we wacked the tank with a 3 pound sledge hammer on the front face (much like if you hit an object on the road) and again it took it like a champ!

Mazdaspeed 3 Auxiliary Fuel Tank

Upon closer inspection we did not find any cracks forming due to the truck test or the impacts of the sledge hammer.  After letting the tank sit for a bit we found that the tank actually formed back to its original shape before the testing.

So what makes the CorkSport Auxiliary Fuel Tank strong and durable?  Two things:

  1. The material used is Cross-Link HDPE (High Density Polyethylene) which is a very durable and resilient material by itself.  Add in the cross-link reinforcement in a 0.190” wall thickness and you now have a material that can handle a large amount of impact force and yielding (bending) without failing.  
  2. The manufacturing process is the other key aspect here.  Unlike welding, there are no seams or welded joints that can fail.  In the rotomolding process, the HDPE is poured into a mold that is heated to the plastic molten temperature.  This powder melts and creates one continuous structure with an average wall thickness of 0.190”.  Even the brass threaded inserts are embedded into the plastic with no seam or seal to leak.

Speaking of those threaded inserts, those are really neat.   When the mold is assembled, there brass threaded inserts are fixture inside the mold in set locations.  These give us the flexibility to have integrated mounting points for the brackets that mount to the vehicle AND for both methanol pumps and the standard 044 style fuel pump bracket.  

Now let’s look at a cutaway of the Computer Aided Drafting Model of the tank so we can see a couple other key design features.  BTW these would not have been possible (or atleast not cost effective) with sheet metal. 

Mazdaspeed 3 Auxiliary Fuel Tank

Probably the most critical and useful features of the fuel cell is the integrated sump for the pump feed.  This is the little area under the blue line.  This “low” zone is called the sump and the point is to create a lower spot for the pump to be fed fuel.  This reduces the chance of fuel starvation during braking and cornering as well as allows you to get the full capacity of the tank to your pump. 

Next you can see a “chamber” on the left side.  This actually sits under the frame rail a bit which allowed us to increase the capacity to ~2.6 gallons but it also serves another purpose.  If you are running a port injection auxiliary fuel kit then you most likely have a fuel return from the regulator; this is where that return line connects.   The low ceiling in this chamber helps reduce aeration of the fuel due to the return line flow.  This green line also sits just below the low level sensor so you’ll know when you are getting close to this threshold.  

Mazdaspeed 3 Auxiliary Fuel Tank

Alright let’s wrap this up.  Designed specifically for the 2007-2013 Mazdaspeed 3, you can utilize the tank for methanol or ethanol fuels and you can switch from either or if you change your setup.  Durable and chemical resistant material used can take beating and once installed the tank and black filler cap basically disappears from view.  

We are stoked to bring a new and innovative option to the Mazdapseed Community very soon.

CorkSport High-Pressure Fuel Pump Rebuild Kit

We are proud to introduce the CorkSport HPFP Rebuild kit for the Mazdaspeed 3, Mazdaspeed 6, and Mazda CX-7 Turbo. Replace every seal in your HPFP with a brand new, E85 safe O-ring/X-ring made to exact OEM specifications. The perfect reliability upgrade to install with your CS HPFP internals, we even include new hardware and a security Torx bit to help the install go smooth. Read on for more details and be sure to give us a call if you have any questions!

Mazdaspeed E85 Safe HPFP O-Ring Rebuild Kit

The potential for HPFP failure

While the HPFP internal upgrade is a must-have mod for any Speed, the rest of the HPFP is commonly ignored. As the cars get older and ethanol blends are used more often, the factory O-rings can begin to break down, causing fuel dilution in your oil, and the potential for HPFP failure. The CS HPFP rebuild kit replaces all your seals so you can be confident that your HPFP is performing exactly as intended.

Was the HPFP system designed with ethanol in mind?

With the MS3 and MS6 coming out right around the time ethanol mixes in gasoline were becoming more common, it’s hard to say if the HPFP system was ever designed with ethanol in mind. We spent months researching and testing on a car and in isolated conditions to find the best O-ring material for gasoline and ethanol blends. Each seal in the CS HPFP rebuild kit uses this material so your Speed will operate properly no matter if you’re using the standard pump gas E10 mix, and E30 mix, or even straight E85!

CorkSport

To ensure the correct size for all seals, we were lucky enough to come across a zero mile DISI MZR engine. The HPFP was disassembled and all seals were carefully measured to ensure each O-ring exactly matches the OEM specification. We even had tooling made to produce a custom X-ring that matches the exact specification of the OEM X-ring. This is vital as the X-ring fits on your HPFP piston and needs a precise fit to ensure an OEM quality seal between the fuel chamber and your cam follower.

Lastly, we include hardware to replace the annoying Torx screws that are used in the OEM HPFP assembly. The small security Torx can be notoriously difficult to remove, so we even include a bit to help with removal. As with all CS products, the HPFP rebuild kit comes with full-color installation instructions to guide you through the rebuild and ensure you know where each and every component goes.

Mazdaspeed3 4″ Intake System

If you’re looking for big power (500+whp) potential for your Mazdaspeed 3 and don’t want to be held back by your intake system then look no further!

Benefits of a huge intake with the easy fitment of a smaller intake

Introducing the CorkSport 4” Intake system for ’07-’13 MS3 (Gen1 and Gen2). Featuring mandrel bent piping, a billet MAF housing, and a large aFe dry flow filter; you can get the benefits of a huge 4” intake with the easy fitment of a smaller intake. We went back to the drawing board for this intake to optimize both fitment and performance. Read on for details!

Mazdaspeed3 4" Intake System
2007-2013 Mazdaspeed 3 4 inch Intake System

We truly started from scratch to ensure the best fitment for this intake. The main change is the way the silicone couplers attach to the turbo inlet pipe. To get the pipe as close to the engine as possible for easy fitment, we use a custom-designed coupler off the compressor of the turbo. The 4” intake pipe fits straight into this, making install just that little bit easier. The biggest change though came at the MAF housing connection.

Takes up less room than some 3.5″ intakes

Instead of using a silicone coupler between the turbo inlet pipe and the MAF housing, the billet MAF housing is TIG welded directly onto the turbo intake pipe. This further helps fitment and helped us maximize filter size (more on that later). What this means is that you end up with a four-inch intake that takes up less room than some 3.5” intakes on the market while retaining the OEM mounting points and OEM BPV, PCV, and boost vent ports. It even fits with our 51R battery box!

Mazdaspeed3 4" Intake System
2007-2013 Mazdaspeed 3 51r Battery Box

The benefit of a 4” intake system is in the flow capacity. Moving up in intake size, even from a 3.5” to 4” offers an increase in maximum flow capacity. A bigger intake equals the potential for a larger volume of air ingested by the engine, which equals bigger power potential. You also increase the maximum airflow that can be read by the MAF sensor before it peaks, but you must get a tune to scale the MAF sensor.

So what does this mean for power gains?

Typically, a lower horsepower car will not see a power bump but, big power MS3’s can see an increase in power, just by reducing the airflow restriction before the turbo. While you may not quite be at a 3.5” intake’s limit at 600WHP, moving to a 4” intake will increase the efficiency of your build and reduce the strain on your turbo, with a chance at some extra ponies along the way!

Increasing piping diameter only does so much if you have a highly restrictive filter. We focused heavily on fitting the biggest filter we could to minimize restriction coming from the filter. We chose aFe’s Pro Dry S material for great filtration and flow, without having to worry about an oiled filter dirtying the MAF sensor. Check out the image below comparing the new 4” intake filter to the filter used on our 3.5” intakes. The new filter’s media is larger than the entire old filter!

Mazdaspeed3 4" Intake System
CorkSport

While the new CorkSport 4” Intake may be a bit different from our normal intakes, we kept the same billet MAF housing design. A billet machined MAF housing ensures accurate and consistent diameter around the MAF sensor itself vs just using a pipe or plastic MAF housing while also letting us have a TRUE 4-inch inner diameter. This ensures that once calibrated, your MAF sensor will read stable and accurate. To be extra sure MAF readings are great, we pre-install air straighteners to ensure your MAF is getting clean and straight air.

Daily drive your Speed with this 4-inch intake system

With the consistent CNC machine inner diameter at a true 4 inches and the integrated air straighteners, you can daily drive your Speed with this 4-inch intake system and have MAF sensor range over 900whp.

2007-2013 Mazdaspeed 3 4 inch Intake System

Each CorkSport 4” Intake System is made from mandrel bent 4” 6061 aluminum tubing for smooth airflow directly into your turbo. The billet aluminum MAF housing is TIG welded into position, as are all ports and brackets to ensure long-lasting strength. Each intake is finished off in a wrinkle black powder coat for a clean look that will match just about any engine bay. We also include your choice of 4-ply reinforced silicone coupler for the turbo inlet. We have 4”, 3”, and OEM diameter silicones so you can be sure your turbo with work great with the CS 4” intake. To finish it off, we include stainless steel T-bolt clamps for the connections, to prevent any vacuum leaks.
