Enhance Engine Performance with Standard Motor Products Z58001 PCV Valve Review

the bottom is the one that came from my car, the top is the one that was on the hoses it ran with. In no case does a vehicle intended for the Part 03 Navigator fit.

It has everything you need except the valve cover bushing that the valve fits into. I'm sure I would pay a lot of money at the dealer for these parts. Most of the details have a…
