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