Radium Engineering GM LS Engine Oil Cap with Breather Port - 20-0539
This product will be available for sale in 2 weeks, but you can pre-order now to receive 10% discount!
The Radium Engineering Oil Cap (MPN 20-0539) is a performance-oriented replacement for the factory oil fill cap found on many GM LS-series engines. This component is engineered to provide a secure seal while offering a path for advanced crankcase ventilation setups.
- Convertible Design: Features a removable center plug that allows the cap to be converted into a dedicated crankcase breather point.
- Customization: Once the plug is removed, secondary accessories can be installed to manage blow-by and crankcase pressure more effectively.
- Direct OE Replacement: Designed to install directly onto the factory oil neck without modification.
- Manufacturer Part Number: 20-0539
Ideal for forced induction or high-performance LS builds requiring additional ventilation options beyond the standard PCV system.
