One, High Performance Fuel Injector for 1988 Mazda RX-7. TLF Performance Fuel Injectors are nationally known for quality and precision. Our fuel injectors are special because they are remanufactured using only stainless steel or titanium internal moving components, each injector's integrated filter is replaced with a premium 20μm brass filter, and all o-rings are replaced with Viton™ nitrile rubber o-rings.
