Show original supplier description
The 2JR Hi-Power Intake Plenum is engineered to significantly boost performance for Gen1 QR25 engines, excluding the Frontier. This intake plenum boasts custom CNC milled throttle plates and machined, decked head surfaces to achieve maximum power gains. This enhancement leads to substantial mid-range power increases and improved top-end performance, resulting in quicker throttle response and better overall driveability for both naturally aspirated and forced induction setups (up to 20psi). Installation is straightforward, as the kit includes a new high-capacity fuel rail and all necessary hardware for a complete setup. Notably, no ECU fault codes or issues are expected, and no tune is required. This makes it a convenient upgrade for street and track applications. This product is designed to fit all Gen1 QR25 engines, with the specific exclusion of the Frontier model.
