We bore out the ends of each of the 4 runners to better match up with the inlet of the TGV. From the factory there is a large step going into the TGV, we get rid of that step for a smoother transition.
Feel like adding the bling factor with function?...add our optional ceramic coating as shown in picture. This item packaged with our brand new Phenolic Spacers adds up to a great, free flowing, cool air charged intake manifold. This item also available for our core exchange program. If you dont want down time you can pay the upfront core fee and get one of our intake manifolds, then get the core fee refunded when you return your old stock intake manifold. You must take all wires/hoses/fuel lines/etc off of the intake manifold before sending it in. If you fail to do this we may charge you for the labor it takes a tech to disassemble everything.
Because of labor intensive purposes porting orders can take up to 3 weeks to complete. Please contact us ahead of time with any questions or concerns.
GrimmSpeed™ Product Warranty
Ceramic Thermal Coating GrimmSpeed™ Thermal Coating will keep those super-heated engine temps out of your Intake Manifold. The cooler you can keep the intake air, the more power your car will make.
Gaskets GrimmSpeed™ Gaskets are the real deal. 20-100% Thicker than OEM. GrimmSpeed™ Gaskets are the ONLY option on the market that are better than OEM Gaskets.
Phenolic Spacer Keep your Intake Manifold as cool as possible with our Thermal Phenolic Spacers. Your aluminum Intake Manifold sits on a super-heated aluminum engine block so the heat quickly transfers into your Intake Manifold. Put GrimmSpeed's™ Phenolic Spacer between the two to keep that heat out of the Intake Manifold. The colder the intake air, the more power your car will make.
