Overview
Sikky Manufacturing Billet Oil Caps
Sikky Manufacturing billet oil caps are high-quality, CNC-machined aluminum replacements for factory oil caps. They're specifically designed for GM LS engines (LS1, LS2, LS3, etc.) to offer better durability, a more precise fit with an OEM O-ring, and an enhanced, custom look for engine bays—often used in performance and LS swap builds.
Additional details:
* Made from 6061 billet aluminum for superior strength and longevity
* Designed for various LS-based engines, ensuring a secure, leak-free seal with a new OEM GM O-ring
* Provides a cleaner, more premium, and customized appearance compared to standard plastic caps, popular in performance builds
* A common upgrade for enthusiasts building custom LS engines or performing LS engine swaps in different vehicles
