Professional Products69604 68mm Polished Throttle Body

Got one cheap through "warehouse deals" and it was the unpolished version, even though the box labeling was correct for the full polish one, and item was still sealed in the bag. Good smooth action, no stiction or sticky spots like the cheap ones. Butterfly had a decent seal, with good machining for TPS, and mating surfaces. Casting overall is good quality, uniform matte finish that is similar to oem. Seems like a a smaller bore than advertised, but thats not a downside, as 67-70mm is overkill for all but turbo applications. Not much room between bore and coolant passages for porting compared to some other aftermarket offerings, be sure to mark the boundaries before port-matching. Check carefully upon getting this to know you got the correct item. I think they are discontinued. Overall, the quality I expect from Professional Products stuff at a good price. This is the GS-R variant. I am not sure of fit on b16/b18c5 style intakes, many fit, some do not.
