LS Cast ALUMINUM VC Billet Oil Fill

The LS Cast Aluminum VC Billet Oil Fill by Top Street Performance is a precision-engineered valve cover accessory designed for LS-series engine builds and high-performance modifications. Whether you're running a stock LS platform or a heavily modified big-block derivative, this billet oil cap assembly replaces the factory plastic filler neck with a durable, stylish alternative that withstands boost pressures and extended engine bay temperatures. Built for serious enthusiasts who demand both form and function, this component eliminates the reliability concerns of OEM caps that crack or warp under extreme conditions.

Machined from cast aluminum with billet detailing, this oil fill cap combines lightweight durability with corrosion resistance—critical for forced-induction and track-driven vehicles. The precision fit ensures a tight seal that prevents oil mist ingestion into the PCV system while maintaining proper crankcase ventilation flow. The VC (valve cover) integration is direct and hassle-free, requiring no additional adapters or modifications to your existing LS valve cover setup. Aluminum construction keeps rotational mass minimal, which is especially important in high-RPM applications where every fraction of an ounce counts toward reliability and response.

This upgrade is ideal for LS1, LS2, LS3, LSA, and LS9 engine platforms, as well as compatible LS derivatives used in custom builds and street machines. Installers appreciate the straightforward bolt-on design that requires no machine work or cutting; simply remove the factory cap and thread this billet unit into place. Whether you're building a supercharged street car, prepping for autocross, or constructing a dedicated race engine, this oil fill cap delivers the dependability and visual upgrade that separates show-quality builds from stock-appearing assemblies. Compatible with both naturally aspirated and turbocharged LS applications.
