Powercoating My Throttle Body

Don't know anyone who has done this but it would seem to me that you would want to stay away from having the inside bore coated. This will change the inside diameter and cause the throttle blade to stick. I would also stay away from diassembling the blade. You may have some issues from doing that as well. Good luck, let us know how it turns out.

Remember - they heat the item to melt/fuse the powder coating; so any seals/rubber/composites that won't stand up to that heat could be damaged. I'd check with the powder coaters for the heat temps. Also, there is a heat limit that the finished powder coating will stand up to - most I've asked about are in the 300F-350F range. I'd want to be certain that high temps from the egr valve/spacer (EXHAUST GAS recirculation) wouldn't damage the coating. If your coolant lines are hooked up, I wouldn't expect a problem. I elected to simply brush mine up, and shoot it with Eastwood's under-hood satin clear. No gloss, just protects that matte aluminum finish - a look I like.
