I understand where you are coming from. I wouldn't prioritize the TB over the CAI, but I believe the results should be additive for the most part. You are reducing restriction / improving flow through the TB which the CAI flows throw so in a way you get better flow into the engine AND better flow through your CAI. The two together are likely to be better than either one separately.The 2 tbs look almost identical... 200$ just for an extra possible 6hp? Not worth it. Beter off just getting a cold air intake amd a catback exaust. Much more worth ur money.
it only voids the warranty if the part that was aftermarket CAUSED the problem.Normally anything aftermarket voids the warranty. But i dont see how they would know unless you had engine probs and they removed the throttle body
