Panel Filters

Panel Filters: the direct-fit upgrade for your factory airbox

A panel filter drops straight into your existing airbox in place of the paper element the car left the factory with. Same shape, same mounting, but built to be cleaned and re-oiled and reused instead of thrown away every service. The job it does is simple: catch dirt before it reaches the intake tract while letting the engine draw the air it needs. If you want a cleaner-flowing filter without cutting into your intake or fabricating anything, panel filters are the easiest swap in the Air Intakes section - no tools beyond what opens the airbox lid.

What we stock

There are 118 panel filters here from 6 brands: BMC leads the range with 71 options, K&N Engineering has 31, HKS 10, plus Perrin Performance, Spectre and Alta. Current pricing on what is in stock runs from $64 to $1,097, so there is a wide spread between a straightforward replacement element and a high-end race unit like the HKS RS for the RB26DETT or the HKS RS for the Z33 VQ35DE.

Fitment data is attached to 108 of these filters, spanning model years 1990 to 2024. Top makes covered include Porsche, BMW, Ford, Honda, Audi, Mercedes, Toyota, Jaguar, Chevrolet, Ferrari, Nissan, Lamborghini, Cadillac and Alfa Romeo. Common vehicles in the range are the Porsche 911, Porsche Macan, Jaguar F-Type, Ford Mustang, Alfa Romeo Giulia, Toyota Tundra, Honda CR-V and BMW M4. Concrete examples: the K&N panel filter for 09-12 BMW X5/X6 4.4L V8, the K&N element for the 17-18 Alfa Romeo Giulia 2.9L V6, and BMC units for the 2019+ BMW X3 M / X4 M and 17+ Porsche Cayenne III 4.0L V8.

How to choose

Start with your vehicle - a panel filter has to match your airbox exactly, so the make, model, year and engine decide it more than brand preference. Within the fits-your-car set, the trade-off is mostly price and pedigree. BMC and K&N cover the bulk of everyday cars and SUVs at the lower and middle of the range, while the HKS RS units sit at the top and target specific performance engines. If you would rather keep the maintenance simple, remember these are reusable and cleanable, unlike disposable paper. Match confirmed fitment first, then pick the brand and price that suit you.

What else you need

A panel filter keeps your stock airbox. If you want more, step up to Cold Air Intakes or a full Cold Air Intake Kit. For related filter options, browse Drop In Filters, Replacement Air Filters and Air Filter Elements. If you run boost, look at Intercoolers to keep charge temps down.
