The K&N 69-6034TS is a Typhoon cold-air intake kit built around a mandrel-bent aluminum tube and an oversized, oiled cotton-gauze filter. The manufacturer positions it as a replacement for the factory air filter and intake tube, and it says the setup is meant to raise horsepower and torque. Its reasoning is that cooler intake air improves combustion efficiency, which is the main airflow case for swapping out the stock airbox. Because the filter is washable and reusable, you avoid repeatedly buying disposable paper elements. For a 2.5L turbo Mazda 6 owner searching for a Mazda 6 2.5T cold air intake or a Typhoon intake for the 2.5L turbo, the kit pairs a free-flowing tube with a reusable filter.
The manufacturer estimates a gain of 10.8 HP at 4510 RPM and 11.2 lb-ft of torque, and notes that real-world results vary by application. Buyers should know the kit is not legal for sale or use in California on pollution-controlled vehicles, and some model years may be CARB-legal, so check the CARB status for your specific application. Fitment details also vary: the manufacturer's product page lists 2018-2022 Mazda 6 L4-2.5L F/I, while its 2018-2019 materials reference the Mazda 6 and CX-9 2.5L. Confirm your year with the manufacturer before ordering.

Yes. The manufacturer says the system is engineered to use the factory mounting points and the factory mass air sensor, so the sensor is moved to the new tube rather than replaced.
The manufacturer says installation typically takes 90 minutes or less with simple hand tools. Expect common tools such as a ratchet with extension, 10mm and 14mm sockets, screwdrivers, and pliers. Disconnect the negative battery cable first, then unplug the mass airflow sensor and the vent lines before loosening the clamps and removing the stock tube and upper airbox. Owner accounts point to the sensor and vacuum-line disconnects as the slowest, most fiddly steps, so label each connector before removing it. Check for vacuum leaks and warning lights after the first start.
