5.0 out of 5 stars 1 Customer Reviews

PRW Industries modular valve cover fitting adapters can help to properly vent your crankcase when you're using custom or fabricated valve covers. These fittings will go on either side of the engine to install a breather or oil catch can (depending on the model ordered). They're machined from billet aluminum and available in different anodized finishes to complement your engine compartment. The adapters also include fittings and O-ring seals.
