Killer B Air / Oil Separator w/ Plumbing Subaru WRX 2008-2014 / STI 2008-2021 | GR-MV3S-C

Part #: GR - MV3S - C. This high - quality air/oil separator from Killer B is a game - changer for your Subaru WRX (2008 - 2014) or STI (2008 - 2021). It uses centrifugal filtration, a well - proven method, to force suspended oil droplets out of blow - by gasses. The collected oil then drains back to the crankcase. Applying vacuum to the crankcase, it improves ring seal, cuts down oil consumption, and boosts power potential. There's no need to clean or replace media, and no baffles to slow down crankcase flow. Crafted from billet and TIG - welded 6061 - T6 Aluminum, it's built to last. The Killer B Motorsport push - lock barb fittings don't require hose clamps, and motorsport - grade hoses are available as an option. It's proudly made in the U.S.A. and comes with a lifetime warranty.

Using this air/oil separator is easy. First, install it following the provided instructions. Make sure all connections are secure. During normal use, the separator will do its job of separating oil from blow - by gasses automatically. As for maintenance, there's no media to clean or replace, so you don't have to worry about that. But do check the fittings and hoses regularly to ensure there are no leaks. If you notice any issues, like reduced performance or oil leaks, check the connections again. And remember, this product comes with a lifetime warranty, so if anything goes wrong, you're covered.
