Use
this valve cover breather filter to keep warm, oil saturated crankcase vapors from re-entering your engine through the intake pipe.
Allowing
crankcase vapor to re-enter the engine hurts performance and leaves a
nasty oily residue all over the inside surface of the
intake manifold.
To prevent this, you can delete the factory valve cover vent hose and
replace it with our breather filter. Sold individually
with a clamp to hold it in place.
