The K&N 69-1503TS is a Typhoon-series complete cold-air intake for the 2.4L four-cylinder in the Acura ILX. A custom heat shield or air box helps protect intake air from the high temperature of your engine bay, and the kit replaces the factory air filter and intake tube. It pairs a mandrel-bent aluminum tube with a large conical filter. Stock intake parts restrict airflow, so this kit is a full replacement, not just a filter swap.
The manufacturer lists an estimated gain of 6.37 HP @ 6069 RPM, backed by a dyno chart and a horsepower guarantee. Its filter can be washed and reused, and the manufacturer says a filter can go up to 100,000 miles between filter services under normal highway driving conditions. Owners on user forums are less certain about real-world results. One AcuraZine member reported that the K&N Typhoon intake reduced horsepower over a stock air box. Treat the 6.37 HP figure as a dyno estimate, not a promise. Also note that California Restricted · Not legal for sale or use in California.
The manufacturer's product listing names the 2016–2017 ILX with the 2.4L engine. Some third-party listings show wider year ranges, but I could not confirm those with the manufacturer. Check the fitment with the manufacturer before you buy for a later model year.
The manufacturer describes the filter as washable, reusable and says it can go up to 100,000 miles between services under normal highway driving. Harsh or dusty conditions will shorten that interval.
No. The manufacturer marks this kit as not legal for sale or use in California, so it is not suitable for California-registered vehicles.
Owners on user forums report mixed results. One member who compared the Typhoon to a stock airbox said it reduced power, so the manufacturer's 6.37 HP dyno figure should be viewed as an estimate.
The manufacturer rates installation time at 60–90 minutes and lists a wrench, an extension, a flat-blade screwdriver, and an Allen wrench as the tools needed. Because the kit replaces the factory filter and intake tube, expect to remove the stock intake components and reuse the factory mounting points. Keep the heat shield in place, since the manufacturer says it protects intake air from engine bay heat. Before starting, review the manufacturer's installation PDF for this part number, especially for battery disconnection and mass airflow sensor steps. Those steps were not confirmed in this research.
