The K&N 69-4537TS Typhoon cold air intake is an aluminum tube air induction system with an oversized air filter, built for the 1.4L turbocharged four-cylinder in the Chevrolet Cruze. Its mandrel-bent, silver-finished tube takes the place of the factory air box and intake tube, so the engine breathes through a smoother, less restrictive path. The listing is titled as a short ram intake, which matches the Typhoon design.
Compared with a stock setup or a cheaper universal tube, this kit is a complete replacement rather than a partial swap. The manufacturer describes the system as guaranteed to increase horsepower and torque, with an estimated gain of 6.36 HP @ 5347 RPM and about 6 lb-ft of torque. Its washable oiled cotton filter is rated by the manufacturer for cleaning every 100,000 miles under normal highway driving conditions, and the warranty is a No-Hassle Lifetime Limited. Owners searching for a 2017 2018 Cruze 1.4T cold air intake or a Typhoon intake upgrade get a reusable, bolt-in solution with an hour-long install.
The manufacturer lists RU-4730 as the replacement filter for this system. The included oiled cotton filter is meant to be cleaned and re-oiled rather than replaced on a routine basis.
The manufacturer states the filter only needs cleaning about every 100,000 miles under normal highway driving conditions. Harsher or dustier driving may call for more frequent service.
The manufacturer lists a CARB Executive Order number (D-269-81) for this system. Details on street legality vary across sources, so confirm the current status with the manufacturer before buying for a California or other CARB-state vehicle.
The manufacturer's install sheet lists a typical installation time of 60 minutes or less with simple hand tools, and the kit uses the factory mounting points. Per the install sheet, the tools needed are a flat-blade screwdriver, a ratchet with an extension, and a 10mm socket, with a T25 Torx noted on some versions. Start by disconnecting the negative battery cable, but write down radio presets and anti-theft codes first, since disconnecting the battery erases stored memory. Use only the hardware supplied in the kit; the manufacturer warns that skipping the provided hardware can damage the intake tube, throttle body, or engine. After installation, start the engine in park with the parking brake set and listen for air leaks, then recheck clamps and connections after a road test.
