Enhance the reliability of your engine and improve performance and fuel economy with the CorkSport Oil Catch Can. By adding an oil catch can, you will increase the longevity of your engine by helping keep unclean crankcase vapors and oil out of the engines intake. Made of billet aluminum for strength, the CorkSport Oil Catch Can includes everything you need for a complete install. Don’t let your Mazda get contaminated by sediment, crankcase vapors, or unclean oil. With the CorkSport Oil Catch Can you will remove unwanted debris that would normally contaminate the intake tract. This allows for cleaner air entering the engine, lower detonation rates and increases longevity.

The CorkSport Advantage:

Superior Construction:Made from high grade billet machined aluminum for strength and low weight.
Unique Cyclonic Design: Uses vacuum force to separate the oil and contaminates from the air and includes an internal disk to prevent backflow.
Easy to Check: Twist the dipstick to check how full it is.
Complete Mounting Kit: Catch can comes complete with a black powder coated steel mounting bracket and 11 ft. of reinforced silicone hose for multiple mounting locations.*
Drain Valve Kit: Emptying the can is as simple as a flick of the wrist.
CorkSport Service and Support: Receive a two year limited warranty, full color installation instructions, all of the needed installation hardware, and knowledgeable telephone support.

This kit includes instructions and supplies for fitment to a Mazdaspeed 3, all other applications may require additional materials or custom modifications.

If you have the Cold Air Intake, you will need to find an alternate installation location for the catch can.

Installation note: If you live in an area which gets below zero you need to empty the catch can before the temperatures drop to maintain the functionality.

So far so good. Catch can looks great and came with almost double the hose needed for install which was nice. I have the MS6 and I couldn't really find a spot for the bracket that came with the OCC so I ended up designing and making a custom stainless bracket to bolt where the factory air box was. Makes it really easy to check the dipstick and reach the valve for draining. As for longevity, I can only say that it has lasted well so far in the 3 days that it has been installed.

Great Item! quality and design spot on. easy instructions detailed on everything you need to do. the pcv valve was the hardest part of the install mainly due to location and space. i took the tube loose from the throttle body first then took a small pair of pliers to the tube near the valve and twisted it back and forth breaking the seal on the valve then just pulled it right off. after that everything was good. catch can is a must have for any turbo set-up factory or modded! thanks CS

Another high quality piece from CS. Solid construction. Complete kit. Crucial item for a safe turbo setup. Helps filter the direct recirculating air - cleaner air means longer life and more power.

I finally got around to installing this when performing the dreaded intake valve cleaning since looking at accessing the PCV valve looked almost impossible with the intake manifold in place. (only took me two years to get around to it)

Apparently the OCC kit is designed with the MS3 in mind as with all the instructions from Cork Sport, understandably since there are thousands more of those on the road than my MS6. So finding a suitable location was more a challenge.

This catch can is large about 9" tall and about 3.5" in diameter. With the mounting bracket add another 1.5" to the height when looking for clearance. The front passenger side behind the side marker light area had space but then you wouldn't have access to the OCC dipstick. Plus the hose routing would be longer and the supplied hose would be too short. So back to the driver's side. There wasn't any place suitable under the intake to mount directly to the frame as no location had enough room height wise unless I fabricate a bracket. So onto plan C.

I am running the SRI and this left the area were the factory air box resonator used to sit vacant. So looking in there, you have the oil cooler radiator and that is about it. Keep in mind, this OCC is tall almost 10", I had to drill holes near the top of the frame rail to clear the oil cooler radiator.

Routing the PCV vent hoses was simple enough, I wanted to tuck it out of the way to not be noticeable, since I have bi-annual emissions testing and the less conspicuous the better. Technically, the OCC shouldn't affect emissions since it is still a closed system but state mandated emissions test void any modifications. So keep this in mind if you live in a testing location.

After all was said and done, I routed the hoses down under the intake manifold towards the center of the radiator, to a gap in the frame and the radiator up in the bumper well. I was left with about 6" of hose when done. So keep this in mind if you are looking to route it discretely to the passenger side, you may not have enough hose.

This is not a performance item so I did not expect any tangible changes in horsepower or seat of the pants experience. One downside is that I am noticing a buzzing noise from under the hood when under boost. Its loud enough to hear it on the freeway. I double checked the drain valve (I bought the additional kit and used Teflon tape on the threads as instructed) if it was closed and if the bracket mounting screws were tight. As it stands, I can't find the source of the noise but the only change to my set up is this OCC.

To me this design makes much more sense than what the other MS3 catch cans do. except when they run VTA on their kits.

The OEM design its flawed, this fixes that issue.

Its a no brainer.

Great piece of hardware. As many have alluded to, removing the tubing from the PCV valve is a pain.. What worked well for me was to rotate the clamp on the PCV valve so that the clips point more or less downward. I have medium hands so I was able to reach up and get both hands in the space where it's located, but you really only need your right to pinch the clamp clips and wiggle it down the tube. It takes a while so be patient! Wiggling the tube after the clamp is off also takes a bit of work and be careful about that plastic PCV valve. The rest of the install was easy and straightforward according to the instructions. I also have an AEM intake so I didn't need the paperclip jig to remove the cam case breather tube. One option that may work if you can't get that hose off the PCV valve is to use a tubing coupler and just go off the side that you removed from the intake manifold side. All in all, a great addition and can't wait to see what kind of gunk gets collected.

REVIEW ADDITION: BEWARE! If you live in an area with a cold winter this product is not ideal. Mine ended up collecting an excess amount of condensation which ended up freezing in the PCV and Cam Case Breather lines resulting in high oil pressure. All of my oil ended up pushing past my new turbo, still not sure if permanent damage was done. Works well during the summer. Not worth switching every season, mine is currently sitting in a box in the garage :(.

Good quality. I have to say on the ms6 finding a spot to mount the bracket took some time, ended up putting in drivers side front bumper on the frame and had just enough hose can't wait to see the crap it catches

Ryan 03/09/2015, 10:37 PM

Great preventative maintenance addition! Very interesting to see what this filters out of the intake system. WARNING: If your turbo seals are wearing and leaking oil (a know problem of the MS6) this will make the issue worse! Had this happen to me but was luckily covered under warranty. The OCC also makes the intake smell slightly, especially when almost full. It is also very difficult to gain access to the PCV valve. Other than this it works great!

Ryan Kelly 12/11/2014, 10:44 AM

Any suggestions on how you would route this catch can on a dual can set up using a perm plate with the other can being vta?

Do I need to clean out the filters in this Catch Can or will draining the oil out when needed simply be enough?

Is there a recommended oil and weight? Would that change when running the catch can? For a 2011 MS3. Thank you.

Would you do everything the same from routing and placement of the catch can for a 09 mazda cx7. I was a bit confused on how it was routed but I think I understand it from the previous questions that were answered.

Will the standard location work with a SRI?

Asked by Austin A | 04/23/2021, 09:40 AM | 1 answer(s)

Why is this routing chosen for the OCC as opposed to a more simpler one such as the damond ms unit. Seems like itwill more pressure on the crankcase doing it the CS way. Please explain the benefits and the cons.

Are there concerns of aluminum can causing the hot engine air to condense in the winter and then freeze? I've hear of this in many applications during the winter, but don't like the idea of uninstalling for winter since it's such a pain to work with the pcv valve on my speed 3. Would an insulated jacket with a coolant line spiraling around the can help with any condensation and freezing?
