An oil catch can is essential on a performance vehicle to protect the engine from elevated levels of crankcase blow-by accumulated from aggressive driving. Excess oil saturated air circulating back into the air intake stream can lead to degraded performance. Unlike many catch cans on the market, this catch can features an integrated oil separator that accelerates oil condensation. This stainless steel filter media is cleanable and reusable.

Can works
This can was a little fancier looking then I needed (would rather have paid $20 less for a completely un-anodized part, but I liked the engineering design that went into it, coming from a fluid mechanics background myself. Based on this alone I decided to try it out on my 2GR-FE powered 1991 MR2. (2GR-FE being the same engine as in the Lotus Evora). I was choosing between this can and two other top-rated baffled cans that are highly popular. One being more expensive, and one less expensive. I was catching blowby after the first hard drive. Bottom line: It works. I'm happy.
