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.
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 Bosch Motorsport EV14 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 each other. To ensure leak-free operation and optimal performance, each injector is then pressure tested up to 220 psi. The results are unmatched cylinder-to-cylinder consistency, even at low pulse width, 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.
The EV14 injector’s superior ball/pintle valves combine with Grams Performance precision-modified nozzles allow for consistent performance up to 118 psi, making them suitable for a wide range of applications, yet without exhibiting any of the high-pressure problems often associated with other injectors. The optimized spray pattern also helps improve mixture preparation as well as atomization. Grams Performance injectors are cold cut with diamond grinders in less than three seconds for high performance with pre-seating. Abrasive cutting creates heat, which leads to poor spray patterns and the need for competitors to pre-seat their injectors to reduce distortion. Each injector is also fitted with high-quality Viton O-rings that are resistant to extreme temperatures and harmful oils found in some fuels.
Each injector set includes dead time compensation values to help ensure consistent air/fuel ratios and optimal performance when tuning. Grams Performance Fuel Injectors are carefully tested and matched in controlled laboratory environments using state-of-the-art equipment and are subjected to rigorous dyno, street, and racetrack testing to ensure proper performance in the most extreme conditions.

Refreshing orange scent
These are effective at refreshing your disposal. When I am done cleaning up my kitchen I put 2 drops in the disposal side of my sink and briefly pulse the disposal to break open the drop. Don't run any water as this will wash away the drop and the fresh orange scent. I am very sensitive to perfume or floral fragrances - these are just the right amount of orange scent to make your drain smell fresh without the scent overwhelming the kitchen.

Easy to use and work great
These are great. Helps with odors and grease cutting. So easy to just drop a couple in after use.

They smell AMAZING!!
Amazing quality, they smell great, and they last quite awhile! I like switching between the orange and lemon scents, as it’s nice to switch it up! A great price for the quantity and quality!

Easy To Use
Easy to use product with nice scent. The scent is a bit lighter than I thought it would be, but I suppose you could use a couple at a time. Compared to other brands I thought a good value as you get more. Seemed to work well. Popped one in, ran the disposal and the smell seemed to be gone.
