The fuel system of your powerful 2013-2020 FR-S, BRZ, and 86 can handle some big power numbers without needing an upgrade, but when you start talking about massive supercharger head units, or even better, upgrades for those head units, you're going to need some high-powered and reliable fuel injectors to keep your FR-S, BRZ, and 86 from getting thirsty.

Allows for Higher Power Levels than the Stock Fuel Injectors for Aggressive Builds

The 2013-2020 FR-S, BRZ, and 86 make decent power out of the gate, and a few modifications and custom tuning can easily push them into crazy new levels of horsepower and torque. However, you will eventually reach a bottleneck when it comes to producing more, and the first of which is your 2013-2020 FR-S, BRZ, and 86's factory direct fuel injectors. The stock fuel injectors can handle most bolt-ons and tuning, but once you have an aggressively-built 2013-2020 FR-S, BRZ, and 86 with full bolt-ons, turbo upgrades, and/or water-methanol, the factory injectors run out of steam. To help take your race car to the next level with all its modifications, you'll need this full set of Grams Performance Fuel Injectors. These injectors drop right into place of stock and increase in fuel over stock, allowing you to squeeze some more power out of your 2013-2020 FR-S, BRZ, and 86 once your car has been properly retuned, which is required for these injectors. When paired with an upgraded High Pressure Fuel Pump (HPFP) and upgraded in-tank fuel pump, these injectors can take your FR-S, BRZ, and 86 even further, for huge power gains over stock.

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 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.

Maintains OEM-Like Function with a Drop-in Fitment

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.
