About Us

Welcome to TLF Performance Parts, your one stop source for custom made Fuel Injectors and High Performance Tuned ECUs. TLF Performance Parts was started because of a failed set of High-Performance Fuel Injectors that had been ordered online! The company sold remanufactured high-performance fuel injectors but provided no warranty or return option (and they are STILL in business). Being a mechanical engineer (and a very unhappy consumer), I researched, designed, performed mill work, and built (“remanufactured”) the fuel injectors for my 1989 Toyota Supra. With new knowledge and because of my previous experience purchasing from a company that would not warrant or allow returns, I opened TLF Performance Parts to remanufacture high quality fuel injectors for High Performance and OEM uses in gasoline engines. We proudly warrant our products for one year from the invoice date against defects in the remanufacturing process, replaceable components, and performance of fuel injectors we sell.

TLF Performance Parts opened on February 21, 2002, in Chatham, Illinois, just 5 miles south of Springfield. That location housed both our manufacturing facility and our retail showroom

We also understand the need to get a part as fast as possible so we have expedited same day shipping so you can expect your part in 3 business days. Also for our local customers we have same day delivery in NYC, Queens, Long Island, Staten Island and New Jersey or offer customer pick at our location.

TLF Performance has a full inventory of electronic fuel injectors. We sell only genuine name-brand injectors manufactured by Bosch, Denso, GM Multec, Delphi, Rochester, Siemens, Keihin, JECS, Pico, Weber, Magneti Marelli, and Lucas.

In most cases we offer OE (original equipment) replacement fuel injectors, and w e also offer carefully cross-referenced, new er generation, replacement injectors which will produce better spray patterns with superior fuel atomization resulting in increased efficiency and better overall performance in your stock engine.
