Show original supplier description
The ADD W1 Oil Catch Can kit is engineered specifically for the 2019 5th Generation Subaru Forester, providing a direct-fit solution with custom brackets, fittings, and hoses for straightforward installation. At its core is the ADD W1 V3 Special engineered TRIPLE Twister Chamber, designed to trap more oil and contaminants. This internal baffle system, a 3-stage chamber filter, operates without affecting PCV/CCV pressures, ensuring efficient filtration of oil and moisture from the blow-by gas. The system effectively prevents oil buildup in critical intake components like the intercooler and throttle body, which can lead to carbon and sludge. Constructed from high-grade, lightweight 6061 Aircraft Aluminum, this oil catch can is built for durability and performance. The closed-loop system integrates seamlessly with the PCV/CCV systems to separate oil particles before they re-enter the intake. The can is fully serviceable, featuring an easy-drain plug or an optional remote quick-drain valve. Beyond just trapping contaminants, the ADD W1 Oil Catch Can aims to improve engine performance by ensuring cleaner inlet air, potentially raising the octane. The advanced design helps maintain a clean intake system even under hard driving conditions. The product comes with a Limited Lifetime Warranty.
