What's up guys!
Big shout to out Sven for sending over these photos and videos! He installed our Ross Racing B58TU Check Valve Inserts and coupled it with our Ross Racing Square Competition Catch Can.
For those that want to still retain their engine cover, as you can see, it is still possible with only slight modifications. Sven did a really clean install and only needed to cut the engine cover in one area.
No reason to sacrifice venting for "looks" by using a baby AN6 hose just so you can route it under the engine cover! Especially for the guys chasing 600hp+, venting through an AN6 hose on the oil cap is a HUGE bottleneck.
You wouldn't run a 2" diameter exhaust on any 400hp+ car so why would you vent crankcase gases through a baby AN6 hose on a B58?? Do it right the first time and go Ross Racing!
Our kit was designed for Form AND Function vs just Form from those guys. This is why our OCC kit is the only one on the market with a Baffled Oil Cap that also uses our first of its kind, custom Check Valve Banjo setup that only vents under boost. No need to worry about pulling in unmetered air and potentially creating a vacuum leak with an open style banjo; especially if you're stock PCV or run Check Valve Inserts. So again, do it right the first time and go Ross Racing!
As always, thank you guys for your continued support!

What’s up guys! Matt from Ross Racing here with what I hope will be a huge announcement!
After months of testing and tweaking, we finally feel it’s ready!
Introducing the Ross Racing B58TU OCC Kit!
This kit, we feel will be the best on the market and it won’t even be close!
Our kit will include our tried-&-true Ross Racing Competition Catch can which have been performing beautifully on the Gen1 B58s running our valve covers, with some guys running 45+ psi of boost! You will also noticed that we have designed an all new squared Competition Catch Can which was deisgned similar to our standard circular version but squared! One more option to choose from depending on your preference! When it comes to venting and baffle design, you won’t find a better option out there than our Competition Catch Cans!
You’ll also notice that there are a variety of OCC braces. Like I said, we have been testing! While not pictured, we have an OCC setup that will fit a variety of cars including the BMW G2X, G30, G42, G01, G02 and Supra A90/A91! This will also include a top mount OCC setup for most options!
Our kit will be the most complete kit on the market and will also offer the most venting in the safest way possible! So no, we will NOT be venting from the lower CCV Port because the point of our kit is to solve crankcase/blowby issues, not introduce new ones! Most of you have already seen my spiel on the idiocy of venting from the lower CCV Port so I won’t stay on that topic but I would like to also introduce you guys to my new, first of its kind, AN10 to AN10 PCV/Check Valve Banjo fitting. This new banjo will attach to my best in class Oil Cap Breather and allow for venting only under boost while staying shut during idle. If you’re stock PCV, this will prevent the risk of a vacuum leak during idle and if you’ve deleted the PCV, during idle, venting from the valve cover PCV port will be sufficient!
Our kit will also only use AN10 hoses as we want to ensure your car is able to vent as much crankcase pressure as possible! No bottlenecks!
As always, thank you guys for you constant support! Means the world!
