High-performance Intake and Exhaust valve set by Supertech for the Ford EcoBoost 2.3L and 2.0L engine along with our motorsport valve stem seals. This is the same setup we use in all of our MRX Engine and Cylinder head builds and has been proven in all forms of applications including high-performance street and drag racing. Intake valves feature a black Nitrided coating over stainless steel, exhaust valves are sodium-filled Inconel to withstand ultra-high temperatures.

This will also fit 2.0L Ford Ecoboost cylinder heads if exhaust valve seats are machined to accommodate the larger RS-size valve.
