Frequently Asked Questions
Will this bolt directly to my turbo, or do I need adapters?
T3 inlet bolts to the head, T4 outlet bolts straight to most common T4 turbos. No adapters needed for standard setups. If your turbo uses a different flange or you're running a non-standard configuration, verify flange compatibility before ordering.
What kind of gasket and hardware should I use?
Manifold ships bare—no gaskets or studs included. Pick up a T3 inlet gasket set and T4 outlet gasket separately. Use quality stainless or mild steel studs rated for manifold temps; many builders go with ARP hardware for reliability under boost.
Can I paint this or does it need ceramic coating?
Stainless won't rust bare, so paint is optional. Many builders leave it raw or hit it with high-temp ceramic for longevity and cleaner engine bay look. If you do coat it, use a ceramic product rated for sustained exhaust temps—standard paint will flake off.
