DESCRIPTION

The COBB Air/Oil Separator is placed within your Ford Mustang'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 Ford EcoBoost Air/Oil Separator 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.

Super soft, runs small, long tail
High quality, super soft, good neck height, nice price, ready to go right out of the dryer, medium thick material, works well under a sport coat or sweat shirt, snug fit--runs about one size small. Length is about four inches too long. So, ideally made for tall and skinny people (I am short and thick), but going one size up works fine for me except have to tuck it in due to the length.

This shirt is a cheat code
Color: Black, White, Navy Blue, Light Gray, Size: XX-Large
These shirt fits my body so perfectly! I’m 6’5” 310 pounds but I look 260 pounds. I sweat easily and I’m very sensitive to the material a piece of clothing is made of. This shirt is lightweight, extremely breathable, and feels like silk on the skin. It compliments and accentuates my contours to enhance my physique. I only tried on one and I’ve already ordered 12 more hehe. This is a cheat code.

I Love the collar
Color: Black, White, Navy Blue, Wine Red, Size: Large
Great T-shirt. I can wear this casually with jeans or with a sports coat. The fabric is soft. There is no label in the collar, so you can wear it however you want.

NOT a compression shirt
Color: Black, White, Navy Blue, Wine Red, Size: Large
These are well made with good quality material but are not what I was expecting given the picture. I am an XL and ordered a L because I wanted them to be tight (which they are not.) I decided not to return them because they are good shirts with a reasonable fit, but be advised these are not compression shirts.
