The Earl's Performance 3434120ERL is a billet aluminum oil fill cap designed to simplify catch can installations on late-model performance engines.

• Accepts AN O-ring fittings or port hose ends for routing to catch tank or PCV system
• Billet aluminum construction with durable black anodized finish
• Eliminates time-consuming and permanent valve cover modifications

Note: This version is designed for OEM valve covers. A separate version is available for Holley cast aluminum GM LS valve covers. Compatible with Earl's ORB hose end AT849010ERL, or O-ring port to AN flare adapters AT985010ERL (straight) or AT949010ERL (90-degree).
