I'm looking at performance mods for my 1998 f150 SuperCab 5.4 4x4 Lariat and one of our local truck accessory shops deals with Helix Power Tower and the Air Max intake kit. Has anyone heard of these, can they recommend or advise against if appropriate. I don't want to screw up my truck.
TIA

 

you may want to do a thread search on "throttle body spacers"

most people here think they are a waste of money.

First mod should be a chip, followed by a cat-back exhaust and of course the K&N filter.

 

I think there are better options than your choices. You may want to look into Power Aid (TBS) and AIRAID intake systems / filters. The AIRAID has the most filtered air compared to all others. Power Aids work but they have a whistle...almost like a turbo spooling up under acceleration.

 

My personal experience with the Helix power tower is that it is >>>>>>>> an expensive paperweight!!
