With the release of the new 2016 Mazda Miata the Mishimoto engineers are hard at work looking for ways to improve engine efficiency. They created this new direct-fit Miata oil catch can system to help protect the heart of your Miata from harmful blow-by. Direct injection engines like the one in the 2016 Miata suffer from accelerated carbon build up due to the lack of port injection which washes the valves with fuel during engine operation. The engineers saw a significant coating of oil build up while examining the intake manifold. The oil was coming from the PCV system which contributed to carbon accumulation and a decrease in octane levels. Mishimoto s new Miata catch can system helps to prevent this blow-by from reaching the intake resulting in a cleaner running engine. Mishimoto s Mazda Miata catch can kit features Mishimoto s 2-port Compact Baffled Oil Catch Can with a bronze filter and internal baffle to better separate the oil from the crankcase vapors. Two direct-fit silicone hoses and an application-specific bracket make for a quick and simple installation. Like all Mishimoto 2016 Miata parts this catch can kit comes with the Mishimoto Lifetime Warranty
