Putting FiTech’s New Wallet-Friendly LS Induction System to the Test

- Jeff Smith and Steven Rupp

 

 

FITECH RECENTLY INTRODUCED a line of affordable and easy-to-install self-tuning induction systems for GM LS engines designed with both the do-it-yourselfer and the professional EFI tuner in mind. The fabricated sheet aluminum intake may be what grabs the eye first but it’s the rest of the kit that really stands out. It’s a complete system that comes with everything needed to finish the induction system of an LS engine and have it fueling accurately with little fuss and for minimal cash outlay—even with the super cool TIG-welded intake manifold. It wasn’t all that long ago that the only place you would see a fabricated sheet metal intake was on an NHRA Pro Stocker or perhaps a highly competitive Comp Eliminator car. The rest of us mere mortals just couldn’t afford those enormously cool but ultra-spendy TIG-welded manifolds. But what was once an extravagance is now affordable.

FiTech garnered such significant attention with its self-learning throttle body fuel injection system that we covered it in the June 2017 issue (“Injection Inspection”) where we compared it to a carburetor on a 440hp 5.7L LS engine. That testing went so well that when we learned about FiTech’s Ultimate LS induction kit, we just had to try it.
