Performance Short Ram Air Intake System for 2002–2006 Nissan Sentra – 2.5L Response & Sound

This performance short ram system is engineered to maximize the Nissan Sentra’s intake velocity. By replacing the restrictive factory air box with a mandrel-bent aluminum induction path, this kit allows the 2.5L 4-cylinder engine to draw in a larger volume of oxygen-rich air with significantly less effort. The result is a more energetic combustion cycle, providing crisper throttle sensitivity and more fluid acceleration, perfectly complementing the nimble handling and sporty character of the B15 chassis.

Made specifically for the QR25DE powertrain, this upgrade unlocks hidden efficiency while maintaining the reliable daily drivability of your Sentra. In addition to the performance boost, it grants your engine a deeper, more aggressive roar under load, while the black powder-coated finish and matching black cone filter ensure the engine bay looks clean and purpose-built for the track or the street.

Key Features & Performance Benefits

• Mandrel-Bent Induction: Features a smooth aluminum intake tube to eliminate turbulence and satisfy the engine’s demand for air.
  

• Instant Throttle Feedback: Removes the "laggy" feeling of the stock intake for more immediate power delivery and sharper revs throughout the power band.
