Built as a drop-in replacement for the factory glove-box cabin filter, the K&N VF2056 is a non-woven synthetic filter that you clean and reinstall rather than throw away. Engineered to be washable, reusable, and durable, this cabin filter is designed to last for the entire lifespan of your vehicle. Over a disposable filter, the payoff is fewer replacements and a cleaner cabin air supply. The manufacturer also markets increased airflow to improve heating and cooling efficiency, which helps the HVAC system work harder on hot days.
Searches for a Mazda 3 2.2L cabin air filter, a reusable glove box cabin filter, or a washable K&N cabin filter for a Mazda 3 usually lead to this part number. Before you buy, confirm that your engine and model year match the fitment list, since the manufacturer's listings show the VF2056 across several Mazda 3 engines. Installation is a glove-box job rather than a tool-heavy one. Typically installs in less than five minutes with no tools required, according to the manufacturer, and the cleaning routine is refreshing your K&N cabin air filter every 12 months, or 12,000 miles, using the K&N Refresher kit pt.# 99-6000.
The manufacturer recommends refreshing the filter every 12 months or 12,000 miles, and it points to the K&N Refresher kit (pt. 99-6000), which includes its own instructions.
The manufacturer lists a No-Hassle Lifetime Limited warranty for this filter.
The manufacturer's product page confirms fitment for the 2018 Mazda 3 2.2L L4 Diesel. The manufacturer's Mazda 3 category also lists the VF2056 for other 2018 engines, and fitment for other model years varies by source. Confirm your engine code and model year with the manufacturer before ordering.
This is a beginner-friendly job. Per the manufacturer's install sheet, you open the glove box, unclip its damper (shock) arm, and press the sides of the box inward to reach the cabin filter housing. Unclip and remove the dirty filter, then vacuum out debris from the housing before fitting the new one. The filter goes in with its locking feature facing down and seated in the housing's locking slot. Reverse the steps to close everything up, then clean a spot on the housing and apply the K&N Stop Decal so the next person knows the filter is reusable. Expect the job to take only a few minutes with no tools, but do not force the tray tabs, since K&N's install sheets for related cabin filters warn that they can break.
