Category: Mazda 6 Turbo
The Skyactiv Mazda 6 turbo is a quick luxury sedan which is easy to modify and CorkSport offers performance upgrade from exhaust, intakes, and suspension for example.
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
block.
Check it out here and get your today…your Mazda will thank
you.

The Solution to all those Boost & Vacuum Hoses – CorkSport Boost/Vacuum Block October 23rd, 2019Derrick Ambrose
That’s right, it’s time to start making more power on the SkyActiv 2.5T. We are proud to introduce the CorkSport Power Series Short Ram Intake for 2018+ Mazda 6 equipped with the 2.5 Turbo Engine and 2016+ Mazda CX-9. We replaced the restrictive factory airbox with a free-flowing intake system that was designed to help your turbo breathe significantly better. The SRI offers better performance, sound, and looks in an easy-to-install package. Read on for full details, and be sure not to miss the sound clips in the video below!
This CorkSport Short Ram Intake was designed specifically to get the best the 2018+ Mazda 6 2.5T and 2016+ Mazda CX9 have to offer. From the precision machined MAF housing to the high-flowing filter, each component in the CS intake system offers an improvement over the stock counterpart while retaining great fit and finish. All mounting hardware, brackets, and clamps are included to make your installation quick and painless.
Starting at the OEM turbo inlet pipe, the factory airbox utilizes a ribbed and flexible rubber elbow. While working well enough, the ribs induce significant turbulence into the intake tract.The CorkSport short ram intake replaces this elbow with a smooth-flowing silicone elbow. In addition, the silicone is 4-ply reinforced with nylon to eliminate any chance for volume reduction under wide open throttle.
Next comes the MAF sensor housing. The MAF sensor essentially reads the volume of air that is entering the engine so the ECU can adjust tuning to suit. Since the OEM unit does a good job here, it was imperative that the CS MAF housing matches to ensure no check engine lights or tuning issues. The CorkSport MAF housing is precision machined from 6061-T6 billet aluminum to match the OEM housing to ensure no CELs, no tuning issues, and great flow.
Finally, the CS SRI uses a performance AEM dry-flow filter. A high-quality filter like this is long-lasting, reliable, and can be washed and reused. It has superior filtration to the OEM filter, while also allowing more airflow into the intake tract.
Now for what you’re all interested in: power gains. By removing the restrictive OEM airbox and turbulent intake elbow, we were able to pick up 5-16whp and 7-23wtq through the rpm range. This power bump comes with no tuning changes and with identical testing conditions. Check out the dyno graph below to see for yourself! Note: the variance in low RPM (2800 and lower) is due to difficulties associated with dyno testing an automatic vehicle.
Freeing up a few extra ponies is great but what you will really notice is the added engine and turbocharger noise. That restrictive airbox does a little bit too good of a job at dampening out all the fun sounds that come with a turbo. We were honestly a little surprised by the flutters, whooshes, and psshh noises that come with the CorkSport SRI. You also gain a little extra engine induction noise under hard acceleration. The extra noise is enough to be fun when you want it but not annoying or distracting when you don’t. Watch the video below to see what it sounds like.

The SkyActiv 2.5T has been around for a few years in the CX-9 however, things started to get interesting when the engine was dropped in the Mazda 6 for 2018+ models. While lacking a manual and not a true Mazdaspeed, it’s a step in the right direction for the enthusiast. With one of the new Mazda 6s in the CorkSport garage, we’ve been getting curious about where all of that 310lb-ft comes from. Well, we decided to call up Mazda and purchase a turbo to see how it all works.
There’s a lot to take in on the turbocharger and there are quite a few things that have changed from the K04 that made its home in the Speeds.
For starters, this turbocharger is pretty big. The wheels themselves are not large, with the compressor wheel very close in size to the old Mazdaspeed K04 & the turbine wheel only slightly larger than the K04. However, with the dual inlet turbine housing, 90° compressor outlet, and lots of attached electronics, the whole package takes up a lot of room in your engine bay.
The turbine housing is not far from the old K04. A large five-bolt inlet flange has two rectangular inlets to work with the dynamic pressure system (more on that later) and even a port where the EGR system sources its exhaust gases. The outlet is much simpler, using a five-bolt flange to mount to the downpipe, yet does house a surprisingly large wastegate port.
From a performance standpoint, the large wastegate should help eliminate boost creep but the turbine housing will likely need a larger scroll to get some more serious power out of the engine.
The compressor side is packed full of features. As usual, the wastegate actuator bolts to the compressor housing, however, Mazda has switched to an electric actuator. Interestingly, the bypass valve is also electric and is even mounted to the face of the compressor housing.
Some fancy casting design leaves a pathway between the high and low-pressure sides of the compressor and let the BPV decide when the passage is open or closed. These two electric actuators will mean easy and consistent boost control. The final plastic component on the housing we believe is a boost-assisted vacuum source for the vehicle. Finally, the inlet is a typical clamp connection while the outlet uses a 90° turn and two-bolt flange for better accessibility around the wastegate actuator.
With the housings removed, the CHRA of the dynamic pressure turbo is very simple & standard. Oil feed in the top, two-bolt oil drain in the bottom, and standard crossflow engine coolant ports. The compressor wheel is a cast 6×6 unit and the turbine wheel is a basic 11-blade unit.
We are looking forward to waking up the Sky-T in the coming months and making the 2018+ MZ6 into something a little closer to a Speed. Stay tuned, there’s much more fun to be had from the 2.5T!
