Frequently Asked Questions
Do I need to prep or paint this flange before installing it?
No prep needed — install as-is. The flange is a functional component that sits inside the engine bay hidden from view, so finish isn't a concern.
Will this work with my turbo setup?
This is a 4AN port flange designed for oil feed applications. Verify your turbo's oil feed inlet matches 4AN before ordering; incompatible port sizes won't mate.
The gasket is already installed — can I reuse it if I remove the flange later?
Plan to replace the gasket if you disconnect the line. Once compressed, gaskets lose sealing integrity. The bolts are reusable, but grab a fresh gasket for a clean reinstall.
