## Description

This is the McNally Dual Valve Oil Separating Catch Can for Corvettes of all years, packages and engines. This is arguably the best dual valve oil catch can on the market. McNally has solved a huge problem plaguing most of the oil catch cans on the market currently. They only remove oil laden vapor during idle and not during acceleration when your GDI engine produces the most blow-by vapor. The reason for a true dual valve can is a secondary vacuum source because without vacuum a catch can does almost nothing. The three high quality AN fittings on top mean you have one line coming in and two lines going out. This ensures the recycled air is returned to the crank case and foul vapors are evacuated from idle to wide open throttle. This system also comes with the most efficient and reliable clean side separators available. Open air breathers just make a mess and create funky odors in the cabin. The McNally clean side separator replaces your factory oil fill cap allowing the crank case to breathe more efficiently. It also alleviates air flow restriction during evacuation cycles. Full time evacuation and true oil separation! What else do you need? At RX Speed Works we have been selling this kit since it was designed and created by the engineers at McNally with over 2000 sold. They created this catch can in early 2015 after collaborating with the originator of the most popular oil catch can ever created. The oil catch can that inspired the McNally design was created by drag racers. McNally is an aerospace company that designs, engineers and builds products for company&apos;s like Mercedes and Boeing. They took something really good and made it great! This is our best selling can and still one of the highest capacity cans on the market utilizing dual valve technology. This kit is in stock now and we&apos;re available 7 days a week to answer questions. ORDER YOUR KIT NOW! Seriously. Order it now and we won&apos;t tell that you bought something else for your truck. Promise. SHIPS FROM USA
