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.

Great Long-Lasting Replacement Heads for BURST Toothbrush
Color: Rose Gold, Color: Rose Gold
I really like these replacement toothbrush heads for my BURST electric toothbrush. They seem to last a very long time compared to many other toothbrush heads I have tried. The bristles hold up really well and do not get worn down or frayed quickly, even with regular use. While I still try to replace my toothbrush heads routinely for hygiene purposes, I honestly feel like these could easily last for several months if needed.
The replacement heads attach perfectly to the toothbrush and feel very secure once connected. I also appreciated that they offer them in pink because it matches my toothbrush perfectly and adds a fun touch. The price also feels pretty reasonable for a three-pack considering the quality and durability of the heads themselves.
My only small complaint is that they are made of plastic, which I personally do not love from an environmental standpoint. I also am still undecided about the black bristles because it can make it harder to tell if the toothbrush is fully clean after use. Other than that, the product arrived exactly as described and pictured, and overall I think these are excellent replacement heads for anyone using a BURST toothbrush.

The best electric toothbrush ever
Color: Rose Gold
Dentists on the tube agree, this is the best clean you can get and at such a low price compared to the others. These heads are durable, they last me like 4 months each, maybe more. Functions great with the vibration levels of the burst and unbeatable battery life.
