K&N Engineering

What are the best K&N intake and filter upgrades for my car? It depends on how far you want to go. A K&N drop-in replacement filter is the easiest win: it slots into your factory airbox in minutes with zero modifications. A K&N Typhoon performance intake system goes further, replacing the stock intake tract with larger-diameter tubing and a cone filter for a deeper intake note. Whichever route you take, choose the part engineered for your exact year, make, and model.

K&N Engineering has been building high-flow air filtration since the 1960s, and its two best-known lines are here. Drop-in panel filters, like the 33-5064 that covers applications from the 22-25 WRX to the 17-22 Impreza and 19-23 Forester, install with no cutting or tuning. Typhoon intake systems, such as the 2.4L kit for the 22-26 BRZ/GR86 and the boxed cold-air kit for the 23+ GR Corolla, replace the full intake path for a bigger breathing improvement. Every K&N filter uses washable, reusable oiled cotton gauze.

Popular picks from this collection include the K&N 2.4L Typhoon intake for 22-26 BRZ/GR86, the K&N drop-in panel filter for multiple Subaru applications, the boxed Typhoon cold-air kit for the GR Corolla, and the K&N intake for the Civic Type R and Integra Type S.

Can I wash and reuse a K&N filter?

Yes. K&N filters are cleaned with filter cleaner, rinsed, re-oiled, and put back into service — one reason owners choose them over disposable paper filters.

Does a drop-in filter require a tune?

No. A drop-in panel filter works with your factory intake and engine calibration — it is a maintenance-grade upgrade, not a power mod that needs ECU changes.

What is the difference between a drop-in filter and a Typhoon intake?

A drop-in filter replaces only the filter element inside your stock airbox. A Typhoon system replaces the intake tract itself — tubing, box, and filter — for a larger improvement in airflow and a more noticeable intake sound.
