This can be fit into our Pontiacs, and they look beautiful. Ive seen them on na gp's but not a supercharged one. but when i was searching on ebay, its not recommended to put these on the supercharged L67's. Why? I was thinkin about doing it anyways but maybe i should ask for your opinions first. I know that they were plastic so they wouldnt get as hot as the aluminum ones because of the s/c but would it really be a factor?

Reason why they wont work is because on a supercharged motor the injectors are in the cylinder heads on a N/A motor they are located in the lower intake manifold. They dont have reliefs cut in them for the injectors.

i seeeee. The person i contacted that are selling these stated that these will foul on the injectors. Yeah im looking for an alternative . The one in the picture is an L32 Version, so these would fit on a newer grand prix 04+? Ive seen em on N/a grand prix 97-03.

I got your PM on the other board. The guy who had these installed goes by 97Coupe on club gp. I believe he is still using these now that he is top swapped.

yes the only way to use those on a L67/L32 is to use the modded LIM and L36/L26 heads

They don't even look that great, not worth changing intake & heads specifically for these.
