3-Inch Cold Air Intake System for 2.5L QR25 Engine

The 2JR 04-06 CAI is a high-performance cold air intake system engineered to deliver maximum horsepower for your 2004-2006 Sentra B15 2.5L and Altima models. This intake is designed to optimize the QR25 engine's performance by promoting velocity and ensuring a smooth airflow path to the throttle body. It boasts a seamless, mandrel-bent 3-inch piping construction with an integrated MAF housing, featuring precise MAF spacing to prevent air disturbances and maintain optimal performance. Constructed with high-polished piping and a dry hi-flow filter, this intake system also offers a unique design that hides the MAF sensor on the backside. It utilizes only one coupler at the throttle body, simplifying the installation and contributing to a clean look. The design has been tested to fit around the stock battery, and it can be modified by the owner into a short-ram setup if desired. This intake is claimed to produce over 8 hp more than a Nismo Cold Air intake and over 15 hp more than the stock airbox, with detailed dyno charts available for comparison. It is also noted as being suitable for supercharged or turbocharged applications. The package includes the seamless high-polished piping with MAF housing, a dry hi-flow filter, a coupler assembly with clamps, a VC to CAI hose, and a securing bushing with hardware.
