hi i got a 98 gt with a 100k on it and i noticed that the intake started to leak around the cross over few thousnd miles ago but now its getting worse so i am going to change it soon, ive been looking on ebay and have found a performance intake for a npi engine that claims 15-20 horse and i was woundering if any body has one and is it worth the extra 100 bucks
 
Replace your stock intake with the PI (Performance Improved) intake found on the '99-'04 Mustangs. The ports don't line up exactly the same, but using a liberal amount of RVT silicone, along with the PI intake gaskets will make sure there are no leaks. Literally hundreds of members here running earlier non-PI engines have done the swap and with great results.

Remember, you're going to want the later intake with the aluminum crossover in the front side otherwise you risk the intake cracking again like your old one.
 
wow thats pretty good i would love to do a pi conversoin with a full aluminun intake but im only 16 so i dont have that kind of money

Well, if you've got to replace it anyway, it honestly doesn't make sense for you to replace it with anyting esle but the PI unit. Especially if it's only going to cost you an extra $100. I mean....you weren't thinking about a little extra money when you added the k&n cai, tb, tb spacer, under drive pulleys, o/r h pipe, mac cat back, and 373's were you? ;)
