What is blow-by and why is it bad for my engine?

Blow-by refers to combustion gases, fuel, and oil vapor that leak past the piston rings into the crankcase. If not properly vented, blow-by can cause increased crankcase pressure, oil contamination, and ultimately reduce engine performance and lifespan. A catch can helps separate these harmful substances from the air being recirculated into the intake.

How often should I empty the catch can?

The interval for emptying the catch can depends on driving conditions and the amount of blow-by your engine produces. Check the can regularly, especially after track days or hard driving. Empty the can when it is approximately half full to maintain optimal performance.

Is this catch can kit CARB compliant?

This catch can kit has not been evaluated for CARB compliance. Check your local regulations regarding emissions-related modifications to ensure legality in your area.

Product Details

Baffled Oil Catch Can Kit, Fits Nissan 350Z 2007-2009 VQ35HR

The VQ35HR is the ultimate evolution of the VQ35 series. The HR was built to be driven at the limit, but over a decade of daily driving and banging the limiter takes its toll. As the VQ35HR ages, it produces more and more blow-by, which makes its way back through the intake system and into the cylinders. More blow-by equals a higher chance of detonation, and the high-revving, high compression HR can't afford more risk. That's why Mishimoto has developed a baffled oil catch can for your VQ35HR-powered 2007-2009 Nissan 350Z or Infiniti.Our complete kit utilizes two 6061-aluminum catch cans that mount in line with the VQ35HR's PCV and CCV systems for protection from idle to wide-open throttle. Blow-by is routed away from the intake and into our catch cans using direct-fit, chemical-resistant lines and CNC-machined aluminum fittings. Our cans are suspended in the engine bay by sturdy 3mm-thick steel brackets that can withstand everything from dirt drops to potholes without flinching.Inside the catch cans, air diverters and a baffle help condense oil, fuel, and water, while a 50-micron bronze filter further cleans crankcase gases before returning them to your intake. Like all our 350Z products, this baffled oil catch can kit for the 2007-2009 350Z VQ35HR is backed by our Mishimoto Lifetime Warranty for a lifetime of protection. So, whether you're hitting the track or the street, protect your VQ35HR with this Mishimoto baffled oil catch can kit.
