The Injen IS1900BLK is a short ram cold air intake built for the 1995-1996 Nissan 240SX with the 2.4L L4 engine, which is the KA24DE. Injen forms its intake tube from mandrel-bent T6-6061 aluminum to keep airflow smooth, and it pairs the tube with a SuperNano-Web dry filter that adds filter surface area. The kit sits in the factory airbox location under the hood, and the black powder-coat finish keeps the engine bay looking close to stock.
Buyers typically compare this kit against a generic eBay intake or a plain drop-in filter. The manufacturer lists CARB Executive Order D-476-2, which matters for owners in California and anywhere emissions paperwork is checked. Injen also states the kit maintains air-fuel ratios with no additional tuning, so you can skip a remap, and it carries a limited lifetime warranty. Owners on user forums report modest gains, with many noticing the change mainly in throttle response and intake sound, so treat this as a sound-and-breathing upgrade rather than a large power jump. Installing this 240SX short ram intake keeps the car legal and avoids the water-ingestion risk of relocating the intake, and the optional hydroshield adds protection for splash and puddle driving.
The manufacturer states the intake provides power gains while maintaining air-fuel ratios with no additional tuning.
The manufacturer lists it as a direct fit for the 1995-1996 Nissan 240SX with the L4-2.4L engine. Confirm your specific engine code before ordering.
The manufacturer lists replacement filter part number X-1014-BB for this Injen intake system.
The manufacturer lists optional hydroshield part numbers 1033BLK (black) and 1033RED (red) for this system.
This is a bolt-on, no-tune swap, so the main job is removing the factory airbox and intake tube, fitting the Injen tube and filter, and reconnecting the sensor and vacuum hoses. Per the manufacturer, no tuning is needed afterward. Owners on user forums warn that clamps on intake plumbing can work loose, so use good clamps and recheck every connection after your first drive. Use the hydroshield if you drive through standing water, since a short ram draws air from low in the engine bay. Exact tool and time requirements were not confirmed in research, so review the manufacturer's install sheet before starting.
