Keep Your PCV System Working Properly With A PCV Fitting From Earl's

Earl’s knows how important the emission system is for modern vehicles. The positive crankcase ventilation system is crucial for the proper operation of your engine. That’s why we developed a push-in PCV fitting for LS engines.
Machined from aluminum and coated in a durable black anodized finish, our PCV fitting fits into the OE grommet hole, replacing the stock PCV fitting without any modification. Originally designed for LS engines, it can also be installed on any system that utilizes a ¾” i.d. PCV grommet in the valve cover. Simply choose a fitting with either a -8 AN or -10 AN male flare and connect it to your PCV system with the appropriate adapter and rubber line.
