Description

FiTech Ultimate LS EFI 1,000 HP fuel injection systems with 102mm throttle body are a complete self-tuning induction system designed for everyone from the do-it-yourself hot rodder to the professional EFI tuner! These Ultimate EFI intake manifold kits are ready to go with everything needed to complete the induction system of your LS engine and get you on the road easily and faster than any system on the market today. So, you can forget about sourcing mismatched parts and cutting and splicing old harnesses and re-flashed ECU's from another unknown tuner source. FiTech has you covered with these complete kits, and they've taken the work out of getting your new or pull-out LS up and running in a flash!
