We are proud to announce a old product that we have redesigned. Introducing the V2 CorkSport Coilovers for 2004-2013 Mazda 3 and Mazdaspeed 3.
We’ve taken the same basic designed and revised and refined it with small changes to fitment and big changes to spring rates and damping rates.
For spring rates we took an approach that seems to differ with most street oriented kits on the market today. We wanted to develop coilovers that were both enjoyable to drive on the street in a daily driven car, but could also perform on the track in more performance oriented settings. With these goals we focus on the ride feedback, understeer/oversteer balance, and suspension frequency balance.
The result; linear rate 7K front springs and 8.5K rear springs. This provided us with a ride quality that was comfortable, but sport focused and with the right balance of understeer vs oversteer, with a car that is more oversteer biased. The frequency of the suspension was also taken into consideration with a higher rear frequency than front to improve driver feedback and comfort.
Like most coilovers, ride height adjustability is essential to setting up you Mazdaspeed 3 or Mazda 3 for your goals. The redesigned CS coilovers offer 2 inches of height adjustability from approximately 0.75 inches to 2.75 inches lower than stock springs. This range of ride height allows you to have a conservative track-oriented setup or a slammed show setup depending on your goals.
With ride height, you can also adjust the front camber setup with the CS Coilovers include front camber plate, this kit comes to your door ready to install.
Lastly, and also somewhat unique to CS, is the design of the front coilovers. Instead of a more conventional and cost effective design, we’ve utilized an inverted damper design for improve performance. By inverting the front damper/shock, we’ve both reduce the unsprung weight of the front suspension and increased the rigidity. Both of these result in increased driver feedback and improved performance.
If you been considering lowering springs or coilovers for you Mazda 3 or Mazdaspeed 3 then give CS a good look. Thanks for taking the time to checkout CS, stay connected on the blog, newsletter and social media channels for upcoming performance parts for your Mazda.
We are proud to introduce the release of a new product: the CorkSport 4.5Bar MAP Sensor for Mazdaspeed 3, Mazdaspeed 6, and Mazda CX-7 Turbo. We’ve had the CS 3.5 Bar MAP Sensor for a while now as it’s a necessity when targeting over 21psi, however, while maxing out the CST6, we found the 35psi ceiling of the 3.5Bar sensor just wasn’t enough. Enter the CS 4.5Bar MAP Sensor!
Before I get into explaining what makes this sensor tick, lets quickly go over what exactly a MAP sensor does on your Mazdaspeed. Manifold absolute pressure (MAP) sensors in a nutshell just read the pressure present in the intake manifold of your car. During normal driving conditions, the sensor is typically reading vacuum (or negative pressure) as the engine sucks in air. While in boost, the sensor reads the positive pressure (boost pressure) produced by your turbocharger. In both situations, this pressure reading is being sent to the ECU so the ECU understands exactly what the engine is doing.
The OEM sensor is a 2.5Bar unit, meaning it can do 1Bar of vacuum (negative pressure) leaving you only 1.5Bar (~21psi) before the sensor runs out of accuracy. Both the CS MAP Sensors allow you to accurately read boost levels higher than the stock sensor, so your tuner can target a higher boost pressure for more power, provided you have the right supporting mods. The sensors themselves do not increase your boost pressure, they simply enable your tuner to safely do so.
Enough learning, let’s get into the 4.5Bar Sensor! The CorkSport 4.5Bar MAP Sensor can read a maximum boost pressure of ~48psi before it starts running out of accuracy. Having a huge potential boost pressure means nothing without a fast responding sensor, so we designed the CS 4.5Bar MAP Sensor to have near instantaneous response of only 2 milliseconds. This means if you have the build and turbocharger to do so, this sensor is ready for just about anything you want to throw at it.
The CorkSport 4.5Bar MAP sensor uses a custom injection molded body that mimics the OEM sensor. This makes it a direct install into the OEM location and a direct plug into the OEM wiring harness. No wiring or adapter harness needed. This results in a clean install that takes as little as 15-30 minutes!
Everything needed for installation is included with the CS 4.5Bar MAP sensor. A new mounting bolt is supplied to ensure everything stays put, while a fresh O-ring is attached to the sensor to provide a good seal in your intake manifold. To top it off, calibrating for the sensor is easy as the calibration for use with Cobb Accessport is laser etched right on the body of the sensor.

When you think of a performance aftermarket component you
typically think of a part that increases the vehicle’s power, but some
performance parts don’t. Instead they have a more critical purpose, increasing
the reliability of your performance engine and components. The CorkSport Oil Catch Can Kit (OCC Kit) is
just that type of component(s).
Why is an Oil Catch Can Kit
critical for your Mazda? Despite the
huge advancement Gasoline Direct Injection (GDI) technology there are still
some downfalls. Compared to the more
conventional port injection fuel systems, GDI is much more prone to engine oil
fuel dilution. This is primarily due GDI
injecting directly into the cylinder; in low speed operation and cold starts
the fuel simply does not have enough time to fully atomize into a gas before
ignition. This results in some excess
fuel seeping past the piston rings into the oil along with any combustion
chamber blow by the pistons. This is
Here you can see the results of a
CorkSport OCC installed for ~3000 miles on a 2018 Mazda 6 2.5T. This engine only has 500 miles and has an
average commute of 15 miles & 20 minutes of mixed traffic and speeds.
Mazda’s OE design attempts to
resolve some of this with a valve cover breather that vents directly into the
turbocharger compressor inlet and a PCV (Positive Crankcase Ventilation) valve
in the engine block that vents to the intake manifold.
Mazda’s setup depends on the fuel
and water vapor inside the crankcase being drawn into the intake manifold and
intake system to then be re-ingested by the engine. This has two major flaws:
The direct crankcase
ventilation via the PCV valve only works while cruising (no boost). Combustion gas blow by will occur most often
while in boost under high throttle application when the PCV valve is closed.
This forces the engine
to re-ingest dirty air that carries contaminants in the form of fuel and water
vapor along with carbon debris. These
containments then build up on the inside of the intake manifold, cylinder head
runners, and the intake valves slowly degrading performance over time.
The CorkSport OCC Kit provides you
with two major features:
Both the valve cover
vent and the PCV valve are drawn from the turbo inlet directly ahead of the
turbocharger compressor. Thus both the valve cover and PCV valve have constant
vacuum in all driving conditions, both cruising and high throttle application.
The oil catch can
itself acts as a “filter” for the vapor and debris that would normally be
directly ingested by the engine. The drawn crankcase vapor and debris is separates
and collects in the catch can for easy removal during normal oil changes.
As you saw above, there is a
significant amount of vapor and fine debris that is being filtered out of the
crankcase air that would have normally been ingested. As you continue down the path of modifying
and demanding more form your Mazda, the need for a OCC System only becomes more
and more critical.

Do you ever open the hood to you Mazda and cringe at all the
boost and vacuum hoses – You know, the string of hoses and T-fittings winding
in every direction? Here at CorkSport,
we’ve had this same feeling and decided to do something about it.
Introducing the Boost/Vacuum Block and Fitting Kit…the
simple and effective solution for your boost and vacuum accessories.
This simple part for your Mazda allows you to consolidate
your various boost/vacuum hoses to one single source. You can finally rid your
engine bay of the numerous T-fittings that plague that single hose that
connects your intake manifold and BPV.
A central boost and vacuum source is plumbed to the block
and then distributed to six standard ports with 1/8-27 NPT threads. If you have a plan and setup you are going
for then opt for the Block and Plug Kit.
If you are unsure about what
you need now or in the future, then the
complete block and fitting kit is your best option.
Either way you are sure to make a huge visual improvement to
your engine bay. A little effort now
will go a long way later with this billet aluminum and anodized boost/vacuum
