The Radium Engineering VTA (Vent to Atmosphere) Baffled Oil Cap Kit is a direct replacement for the OEM oil cap on LSX and LT-series V8 engines. Machined from billet 6061 aluminium and anodised for durability, this cap prevents the crankcase from pressurising by venting filtered air to atmosphere. The integrated air/oil separating filtration is service-free, and the 10AN adapter fitting features a built-in check valve for roll-over protection.

Features

• Direct OEM oil cap replacement — no modifications required
• Anodised billet 6061 aluminium construction
• Vented design prevents crankcase pressurisation
• Integrated air/oil separating filtration — service free
• 10AN adapter fitting with integrated check valve for roll-over protection

Important Notes:

1. VTA kits are not permitted in some racing organisations and sanctioning bodies — check your regulations before purchasing.
2. Depending on the vehicle, an ECU fault code may be triggered as the engine is no longer burning all metered air.
3. If the engine is degreased, the filter must be covered to prevent foreign liquids from entering the engine.
