This is Ford Performance's oil-air separator for the 2017-2020 F-150 3.5L EcoBoost, including the Raptor. It mounts on the passenger side of the engine and uses a molded canister with a dedicated filter media to pull oil vapor out of the PCV air before it reaches the intake. Unlike universal catch cans, it is built around the EcoBoost's specific PCV routing with OEM hoses and fittings, and it drains by pulling the PCV lines and removing the canister. It suits 3.5L EcoBoost owners who want to cut intake and valve carbon buildup with a factory-engineered part rather than a generic can.

This is the Ford Performance engine oil air separator, part number M-6766-35T. It fits 2017-2020 F150 trucks with the 3.5L engine, including the Raptor. The canister mounts on the right-hand (passenger) side of the engine.
A precision-molded canister with a filter media separates oil vapor from the air in the PCV system. It is engineered specifically for Ford EcoBoost family engines, not as a universal kit. Installation uses OEM-quality hoses and fittings.
To drain the canister, remove the PCV lines from it, take the canister off, and pour out the oil. It is engineered and manufactured in the USA.
