Radium Engineering GM LS Baffled Oil Cap with Breather 

This Anodized aluminum billet oil cap kit prevents the crankcase from pressurizing. The vented oil cap adds additional air/oil separating filtration to the crankcase that is service free.

The 10AN adapter fitting features an integrated check valve for roll-over protection. 

NOTE:
1. VTA kits are not allowed in some racing organizations and sanctioning bodies.
2. Depending on the vehicle, an ECU code could be trigged since the engine is no longer burning all the metered air.
3. If the engine is degreased, the filter must be covered to prevent foreign liquids from entering the engine.

WILL WORK WITH OEM OIL FILL CONNECT ONLY.  IF YOU ARE UNSURE WHAT THIS MEANS,  LOOK AT THE IMAGES TO ClARIFY.  DOES NOT WORK ON OTHER AFTERMARKET VALVE COVERS WITH BUILT IN CAPS OR DOES NOT USE THE OEM OIL FILL CONNECT.
