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
Check it out here and get your today…your Mazda will thank

With a shop full of enthusiastic car guys and gals we are in love with the look and sounds of the CorkSport Cat-Back on that larger than life CX-9. Customers love the sound, especially when completed with our Skyactiv Turbo Intake, but a few requested a little bit less racecar rumble.
We are here to give our Cx9 customer what they want which brings us to a new exhaust option for the Cx9 Turbo, an Axleback!
The Axleback exhaust setup is great because you are still getting the awesome 100mm double wall slant cut tips, the high flow 80mm stainless steel piping, and an exhaust note that will still capture your attention as well as the other Cx9 owners on the road.
The in-cab exhaust volume and tone are much more subtle than the catback exhaust setup. This is your family friendly and wife approved exhaust for the Mazda CX-9. This is the “bluetooth office friendly meeting” exhaust system which is mellow at cruise but throaty when you get into the boost.
You can have your cake and eat it too. Check out the product listing for full details.
