This might be the wrong thread for this topic and I agree with you BrianT. I strongly agree to buy "North American" and that comes from a guy that daily work driver is a Honda FIT because it was the economical choice for the quality presented. I worked for my fathers GM dealship for years and GM in Oshawa, Ontario.

I did not post here to encourage other to buy off shore. I simply stated facts based on my experance and observation and some personal opinions on the big picture, as I see it. :oops:I like your feedback and please do not get the impression I support pirates or counterfieters but, It's a fact of industry these days. Buyer Beware/U Bee the judge. -END-

Brad, I respect your opinions and I see nothing wrong with debate. So - did you actually run both intakes? I can tell you from my limited experience that:
1. the material the one counterfit I handled was cast from was a different aluminum. It was much more brittle, drilled and tapped differently, and had a lot of evidence of casting porosity. This was verified when coolant began seaping out the rear of the intake when the cooling system was pressurized. Not the gasket mind you... through the casting of the area adjacent to the cooling passage in the head.
2. The power level went up by a feelable amount (per the car's owner who did the actual swap) and the AG needed a completely different carb set up due to increased airflow (overall significantly more jet).
3. Visually the intakes are close. Not exact. I'd invite you to measure the port volumes of a counterfit vs AG. We talk a lot about how critical a small mark or surface feature is to head porting and that small changes reap huge rewards or kill flow. What do you think small changes in the intake's runners do?

This is part of a quote I have hanging on the panel in front of me right now...
