Message: [QUOTE="Camstyn, post: 516296, member: 16494"] I have read that both the K&N FIPK system as well as the Hypertech Power Programmer only really help at wide open throttle.. One fellow said to forget about using 87 octane, it's now strictly 92 octane, and that's WITH a cold 160 degree thermostat. Plus, the FIPK system is an open box. It doesn't seem like a big deal, but look at your engine compartment, my guess is that you don't want your airbox/filter area to look like that! :scream: Apparently UPD makes a better air intake than the K&N, which has a cover on it to protect it from the road spray that comes through your grill/hood. Superchips also makes a superior programmer to what Hypertech has to offer. [/QUOTE]
