Show original supplier description
The 2JR Racing Hi-Power Intake Plenum Full Kit is engineered to significantly enhance the performance of Gen1 QR25s engines. Constructed from Billet Aluminum with a recommended 76mm throttle body adapter, this plenum offers an 18% increase in plenum volume for optimal performance. It is suitable for both naturally aspirated (low and high compression) and forced induction applications, handling up to 20psi. Users can expect quicker throttle response, improved driveability, and substantial horsepower increases, with claims of over 28whp in the midrange. Installation is straightforward and does not require a tune. The kit includes a new high-capacity fuel rail and all necessary hardware for a complete installation. It fits all Gen1 QR25s engines, with the specific exclusion of the Frontier model. Optional components like the 2JR 1-piece Moto-style cold air intake are also available.
