Similar to our small oil catchcan with the addition of a larger body, fluid level gauge, and K&N; filter. If you find that your intercooler and intercooler pipes contain a lot of oil its because the vent hose that runs from the valve cover to the turbo inlet hose puts a lot of oily blow by into the intake, intercooler and piping. When oil builds up inside the intercooler it drastically reduces the intercooler efficiency. Sure you can spend $10 and install just a small breather filter but that will not resolve the problem, once the filter soaks with oil it will start blowing all over your engine bay....what a mess that is. This catchcan will hold the excess oil that comes from the valve cover and allows the oil to be drained when needed. The unit features 2 heavy duty brass inlet fittings, and a brass drain valve. The universal mounting bracket on the backside has (2) 3/8" holes for easy mounting anywhere you find room.
