The K&N 69-4524TS is a Typhoon-series cold air intake for the 1.4L four-cylinder Chevrolet Sonic. It is a free-flowing, mandrel-bent aluminum tube air induction system. It replaces the factory filter and airbox housing with a silver powder-coat tube and a red oiled cotton-gauze filter. The manufacturer says the tube smooths and straightens incoming airflow so the engine can draw in more air than the stock setup allows.
Against stock, the manufacturer publishes an estimated 7.05 HP gain at 5,474 RPM, taken from a dyno chart on a 2012 Sonic 1.4L, plus an estimated 7.9 lb-ft torque gain. Treat both as estimates, not guarantees. Compared with a generic filter swap, the kit's value is in its service life: the manufacturer says the filter only requires cleaning every 100,000 miles under normal highway driving conditions. The manufacturer also lists a 10-year/million-mile limited warranty and states the kit will not void the vehicle warranty. Sonic 1.4L owners searching for a washable 1.4 turbo intake upgrade should confirm their model year against the manufacturer's application list before ordering.
The manufacturer lists the kit for the Chevrolet Sonic L4-1.4L fuel-injected engine from 2012 through 2020. Confirm your exact year and trim against the manufacturer's vehicle applications list before ordering.
No. The manufacturer states the kit is not legal for sale or use in California on any pollution-controlled motor vehicle.
Yes. The manufacturer says the intake tube accommodates the factory mass air sensor, so the sensor stays in service.
The manufacturer lists a typical installation time of 60 to 90 minutes using existing factory mounting points and simple hand tools: a wrench, extension, flat-blade screwdriver, and Allen wrench. The heat shield installs into the space the old airbox occupied. Owner reviews on the manufacturer's site advise bolting the L-bracket that attaches to the engine mount first, because the mount bolt is hard to reach once the heat shield is in place. One owner of a hatchback model reported adapting the bracket to fit, so check your body style before starting.
