TD05 Flange Aluminum Gasket

Do I need to replace my gasket if I'm already running a turbo?

If your current gasket is leaking boost or showing signs of heat damage, yes—aluminum gaskets are worth the swap for reliability. Even if it's holding, aluminum handles thermal cycling better than stock materials, so it's good insurance on a modified car.

Will this gasket work with my existing turbo housing, or does it require machine work?

This gasket is engineered for direct fitment to standard TD05 turbo flanges. No modification to your housing is needed—it bolts straight in using your factory mounting points.

Should I use sealant when installing this gasket?

Aluminum-to-aluminum flange seals typically don't require sealant if the gasket is seated flush. Torque your bolts evenly and in a cross pattern to compress the gasket properly. Check your turbo manufacturer's spec if you're unsure.
