Product Description

AIR/OIL SEPARATORS FOR FORD ECOBOOST VEHICLES NOW AVAILABLE!
Air/Oil Separator for Ford Focus RS 2016-2018
Cobb has released a brand new product, the COBB Air/Oil Separator for the Focus ST, Focus RS, and Mustang Ecoboost vehicles! These separator cans and fittings are 6061 aluminum anodized black for that clean engine bay look and to match the other COBB parts you have in the engine bay. One thing you may notice as that we are also sandwiching between the factory baffle plate on the engine with our COBB unit which introduces some extra baffling to the oil flow. But it doesn’t stop there, the can contains a custom swirlpot design element that provides additional baffling to the system.
This part is legal for sale and use on Emissions Controlled Vehicles in all 50 states when used in accordance with the manufacturer's application guide because it has a California Air Resources Board (CARB) Executive Order (EO)
DESCRIPTION
The COBB Air/Oil Separator is placed within your Ford RS's crankcase ventilation system and helps to prevent oil vapors from being introduced into the intake system. The COBB Air/Oil Separator is of our own design and has been in the works for years, making tweaks and updates to ensure that it is a seamless installation, clears any third-party emissions, an is the perfect upgrade to your engine.
Ford's EcoBoost engine doesn't have a great spot to tap in, so we went with the route of incorporating the factory breather plate with a spacer plate that we created from 33% glass-filled nylon and is injection molded for perfect fitment. The COBB oil drain plate is sandwiched between the OEM air oil separator and engine block. It uses an additional COBB provided OEM gasket to maintain a leak-free interface with the engine block.
The COBB Air/Oil Separator system installs in series with the original PCV circuit, forcing air from the crankcase through a swirl pot and series of baffles that promote heavier oil particles in the blowby vapor to condense and collect as a liquid at the base of the canister. A drain line returns this condensed liquid oil to the crankcase.
This AOS kit that utilizes a drain-back system keeps valves cleaner and reduces chances of detonation by removing oil particles from the PCV gasses going to the intake manifold. This equates to a cleaner and stronger engine that can push more power with less maintenance or risk.
WHY?
The COBB Air/Oil Separator for Ford Focus RS helps to prevent crankcase oil vapors from recirculating back through your engine's intake system.
Oil vapors passing through your engine's intake system lower the effective octane rating of fuel and can contribute to both oil and carbon buildup over time.
