From my understanding the 96-98 Cobra's intake doesn't have enough runner thickness to do anything over a slight smoothing. Plus, I don't know of any place that can do the 96-98 intakes because of their shape. I may be wrong so someone correct me if I am. Also I don't think that you would see much of a RWHP gain (maybe 5hp) by just having the extrude hone done. Just my $.02
Do a search on the intake topic and you should find some pretty interesting info. Blown46Cobra would be a good "Username" to search for also. He has modified a stock intake to perform as well if not better than the PHP intake.
