Besides the obvious aesthetic appeal, these Breathers will prevent the typical hose blow-off one has on built applications. These units will provide a rock solid connection to your catch can setup.

Included in this package are 6 hex head bolts, and 2 Breather Adapters in -10 AN size. You need only supply your choice of gasket sealant to ensure a proper seal. P&L Motorsports Breather adapters were developed in conjunction with our drag race program. Nitrous and high boost (30+ PSI) applications will typically have engines built loose to handle the incredible amounts of piston expansion seen in forged applications.

The unfortunate by product is blow-by. If the factory lines are capable of venting in the first place, they usually blow right off causing an unbelievable mess, and potential for oil fire, etc. By moving to a dedicated, AN connection, all those fears are eliminated in an elegant package. These Breather Adapters are currently designed to work on non-AVCS EJ20 heads.
