I did this mod a few K miles ago with no problems. No leaks, problems of any kind. Most of the problems arise from not re connecting the vaccum lines correctly. There is way more power above 3K with this simple inexpensive mod. I also did the cam swap ( SHM 2730's ) using the AFM cam tool. I did the swap with no help and had "0" problems. The cams again added mucho power above 3K. There is no need to mess with the EEC. It will find the new A/F curve after a few miles of running. I reprogrammed my chip to take full advantage of my new combo. Any NPI guy should do this MOD ( intake ) even if you plan on going with the PI heads ( you'll need intake anyways ). This is the best and cheapest mod for our cars there is. ( besides gears ) DO IT NOW!! Don't let it scare you!

Dyno before intake/cams = 225 rwhp ( P&P NPI Heads, many mods )

Dyno after intake/cams = 261 rwhp ( lots of mods, new chip )

pi intake $ 80 - $100 , pi cams $ 75- $100 = 25 - 30 rwhp easy!!
