PCV Breather—Machined from 6061–T6 Billet aluminum, the PCV Breather matches Earl's breather in appearance. The difference is the PCV Valve hidden inside. These breathers are available with either 3/8" slip–on hose connection or #6 AN hose end. Now you can eliminate that unsightly PCV valve.
Breathers come complete with a rubber grommet to permit installation of Earl's push-in breather on valve covers using either push-in or twist-in breathers. Breathers require minimum hole diameter of 1.22".
