Default GrimmSpeed Ceramic Coat Throttle Body

I've searched and can't find anything quite on point. I am sending my Throttle Body in to get port and polished. I was debating on getting the Ceramic Coating for $49 more. Is the ceramic coating worth the extra money? I know a lot of it depends on the mods so I listed them below.


Power / Fuel Mods:
1. APS S/R 50 Turbo -2.4 inch inlet, ported exhaust turbine and wastegate entry and outlets, slightly cut out wastegate divider wall.
2. APS Turbo inlet tube
3. STI Top Mount Intercooler with Forge ATMOSPHERIC BOV
4. TGV Deletes
5. Deatschwerks 850cc injectors
6. Perrin Fuel rail kit
7. Toyota Supra (Denso) Turbo Fuel pump

Exhaust Specific Mods:
1. Turbo XS Cast Up-Pipe
2. Stromung Divorced 3 inch Downpipe and cat delete pipe
3. Cobb 3 inch Forester Catback
4. Ported exhaust manifolds

No, not worth it. It's such a small piece in comparison to others, that the effect will be negligible at best. I still have my doubts in its usefulness on many other parts they coat. Exhaust NOT being one of them though. Save your money.

I'm on CORN YO!


I buy ceramic and it costs about 20 shipped for enough to do 50+ throttle bodies. For the price it's probably not worth it if you are ONLY doing the TB. In the long haul every little bit counts. Everything of mine has heat dispensation, ceramic coating, heat wrapped including my fuel lines, block, and FMIC piping. It definately help when you look at everything but having only 1 thing done is not really worth it.
