In high-performance builds, even the smallest components play a critical role and the oil cap is no exception. At Turbosmart, we’ve taken a simple, often-overlooked part of your engine and completely re-engineered it with purpose and performance in mind.
Meet ModCap — our new range of billet, CNC-machined oil caps built for the most popular high-performance engines on the market. These aren’t just for looks (though they do look great). ModCap is all about modular function, durability, and seamless integration into your engine bay.

BUILT FOR PERFORMANCE, NOT JUST LOOKS
Precision-machined from high-grade aluminum, ModCap offers outstanding heat resistance, strength, and exact tolerances. This is a professional-grade solution for builders who demand more from every detail. At the heart of ModCap is its interchangeable center port, allowing you to turn a standard oil fill point into a powerful multi-function tool.
Whether you’re monitoring crankcase pressure with a 1/8 NPT sensor, ventilating excess pressure to a catch can or breather setup, or creating a clean oil return path in a custom turbo install, the ModCap gives you the flexibility to do it all, without compromise.
ModCap gives you options, without needing to drill into valve covers or modify your setup.

MODULAR PORT OPTIONS
The modularity means you can adapt the cap to suit your needs in seconds, going from blocked off to fully functional with ease.
- 6AN to 12AN Hose Fittings
- 1/8 NPT Sensor Ports
- Blanking Plug

FITMENT & COMPATIBILITY
Available in a range of colours and with OE fitment for popular Ford, GM, Mazda, Nissan, Toyota, Subaru and -12AN models there is no reason not to bling up your engine bay today.
Whether you’re focused on engine breathing, expanding your sensor capabilities, or simply elevating your engine bay setup, ModCap gives you the flexibility and reliability to make it happen.
