Premium materials, advanced manufacturing techniques, and stringent quality control procedures make Grams Performance the leader in high-performance fuel injectors.\u003c\/p\u003e\n\u003cp\u003eAn engines' fuel injectors perform a vital role in the accurate metering and atomization of fuel. Grams Performance accomplishes this with its high-impedance Bosch Motorsports 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’s, 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.\u003c\/p\u003e\n\u003cp\u003eThe EV14 injector’s superior ball\/pintle valves combine with Grams Performance’s 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 aso helps improve mixture preparation as well as atomization.\u003c\/p\u003e\n\u003cp\u003eGrams 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.\u003c\/p\u003e\n\u003cp\u003eEach 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 race track testing to ensure proper performance in the most extreme conditions.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eFeatures\u003c\/strong\u003e\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003eHigh-impedance design (no resistor box required)\u003c\/li\u003e\n\u003cli\u003eCold-machined tips for high-precision operation\u003c\/li\u003e\n\u003cli\u003eUltra-fast solenoids for precise fuel metering\u003c\/li\u003e\n\u003cli\u003eLinear response across wide range of operating conditions\u003c\/li\u003e\n\u003cli\u003eAll injectors balanced, blueprinted and matched within one percent\u003c\/li\u003e\n\u003cli\u003eCompatible with all known fuels including gasoline, methanol and ethanol\u003c\/li\u003e\n\u003cli\u003eUnmatched cylinder-to-cylinder consistency and optimal idle quality\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"Grams Performance","offers":[{"title":"Default Title","offer_id":32085926707245,"sku":"G2-0550-0707","price":632.0,"currency_code":"NZD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0315\/1727\/8253\/products\/550-injectors_29_50b41078-74af-45c2-91a1-bbd5f0c5a915.jpg?v=1579578513","url":"https:\/\/speedscienceproductbackup.myshopify.com\/products\/grams-550cc-nissan-240sx-s13-s14-s15-sr20-top-feed-11mm-injector-kit","provider":"speedscienceproductbackup","version":"1.0","type":"link"}
