Grams Performance Injector Kits - B/D/F/H/K-series

Grams Performance Injector Kits - B/D/F/H/K-series

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 Performance injectors are cold-cut with diamond grinders in less than three seconds for high precision without 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 Grams Performance B/D/F/H/K-Series Fuel Injector Kit includes four Grams Performance Fuel Injectors and four Pigtail Adapter Harnesses for easy adaptation onto any Honda K-series engine.

Each injector set also 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.
