Grams Performance is proud to offer the most innovative high-performance fuel injectors for today's performance vehicles. Premium materials, advanced manufacturing techniques, and stringent quality control procedures make Grams Performance the leader in high-performance fuel injectors. Grams 1150cc injectors feature stainless internals and compatible with all fuels including oxygenated fuel with MTBE. Compatible with all fuels including FTW, Q16, M5, C45 etcs. An engine's fuel injectors perform a vital role in the accurate metering and atomization of fuel. Grams Performance accomplishes this with its high-impedance fuel injectors that are modified for high-performance use. Each injector is individually balanced, flow tested, and dynamically matched for characterization within one percent of one another. The results are unmatched cylinder-to-cylinder consistency, even at low pulse widths, as well as optimal idle quality, response, and performance. Grams Performance Fuel Injectors' ultra-fast and precise solenoids feature a linear response curve across a wide range of operating conditions and can accurately meter fuel even at the highest pressures and shortest pulse widths.
