Construction & Design

The throttle body and adapter are expertly crafted from premium 6061-T6 billet aluminum, known for its excellent strength-to-weight ratio and long-lasting durability. Precision CNC machining guarantees a flawless fit and finish, ensuring reliable performance and longevity under demanding conditions. The innovative serrated and swirl design inside the throttle body promotes intake air turbulence, which improves fuel atomization and combustion efficiency. This engineering results in a more complete combustion cycle, translating to enhanced horsepower, torque, and throttle response.

Performance & Sound

By increasing the throttle body diameter from the stock 80mm to 90mm, this kit allows a greater volume of air to enter the engine, supporting higher power output and quicker throttle response. The improved airflow and combustion efficiency contribute to smoother engine operation and a more responsive driving experience. While the primary focus is on performance gains, the enhanced airflow can also subtly enrich the engine’s induction sound, adding to the overall driving excitement.
