The K&N 33-5027 is a panel-style, washable High-Flow engine air filter built on oiled cotton gauze media, sized to replace the factory element in the 1.5L L4 airbox of the 2015 Honda Fit. The manufacturer describes it as designed for high air flow while maintaining filtration levels critical to long engine life. Because the element can be cleaned and re-oiled with a K&N Recharger kit, a buyer who would otherwise keep replacing paper filters can reuse it, and the manufacturer backs it with a lifetime limited warranty. Real-world gains are debated, though. One owner on a user forum reported that a K&N drop-in filter offered no performance benefit over stock. Other owners described a noticeable change in throttle response, so set expectations for an airflow and reusability upgrade rather than a guaranteed horsepower gain.
Fitment and installation are where this part is simplest. The manufacturer states the filter fits into the stock air box of 1.5L DOHC i-VTEC models without modifications. Expect a quick swap: the manufacturer says owners can install a washable K&N filter in about five minutes. Search terms this part typically targets include 2015 Honda Fit 1.5L reusable drop-in air filter, GK Fit i-VTEC intake filter, and K&N 33-5027 cleaning and re-oiling.
The manufacturer lists it for the 2015–2020 Honda Fit with the 1.5L L4 engine. Some other listings show 2014–2019 applications and also include the HR-V, so confirm your application with the manufacturer's part lookup before ordering.
The manufacturer states that K&N drop-in replacement filters typically need servicing once every 50,000 miles under normal highway driving conditions.
Yes. The manufacturer says these High-Flow filters can be cleaned and re-oiled with a K&N Recharger kit as often as reasonably necessary.
This is a beginner-level swap with no tools needed for the filter itself. Open the airbox, lift out the stock filter, wipe the sealing surfaces clean, and seat the K&N panel with its tabs and engraving oriented as the airbox allows. The manufacturer's install hints note that some K&N filters go into the lid first, so hold the filter in place with your fingers while reseating the lid. Disconnecting the intake tube from the airbox lid can make the lid easier to maneuver. Clip pressure will feel firmer than with a stock foam-sealed element, so if the airbox flexes or the lid will not seat, stop and recheck alignment to avoid cracking the housing.
