The K&N 69-6035TC is a 69 Series Typhoon cold-air intake built around a mandrel-bent aluminum tube with a gunmetal gray finish. It pairs that tube with a washable, reusable oiled cotton filter, which the manufacturer lists as the RU-5176 replacement. The manufacturer's estimate is roughly 8.33 HP at 5487 RPM and about 6.5 lb-ft of torque. Those are estimates, not guaranteed dyno results, and published figures for this kit vary, so confirm current numbers with the manufacturer. Compared with a restrictive factory airbox and tube, a smoother aluminum intake path and a high-flow cotton element are a practical upgrade for a 2.5L L4 Mazda 3 driver who wants better throttle response and a more audible induction note without replacing disposable filters.
This is a fuel-injected 2.5L L4 application. The manufacturer's listing for this part names the 2019-2020 Mazda 3, and year coverage differs across sources, so check your model year before ordering. Keep in mind that the manufacturer states this intake is not legal for sale or use in California on any pollution-controlled motor vehicle.

The kit ships with three stainless steel worm-gear clamps and one coupler, and the manufacturer describes the installation as straightforward. Check the included hardware against the instructions before you start, and plan to use a dry filter care routine so the cotton element stays effective.
