Product Details

This is a K&N tapered conical air filter specifically made for your 1986-1989 Honda TRX250R. It's designed to replace your stock filter, giving you better airflow which can lead to improved horsepower and acceleration, especially important when you're out riding in dusty conditions or at higher altitudes. Clean carburetion is key, and this filter helps ensure that.

K&N uses multiple layers of woven cotton gauze media for excellent filtration, trapping dirt and debris while letting plenty of air through. This means you get a large filtration area, so it can go longer between cleanings. Plus, it's washable and reusable, so you can clean it, re-oil it, and put it right back in. It's built to fit directly into your OEM air box with a specific sealing bead, so you know it's going to fit right without any fuss. You generally won't need to make any changes to your fuel system to see the performance benefits.

This filter is a solid option for anyone who rides their TRX250R in demanding off-road environments. It's pre-oiled and ready to go, so you can get it installed and back on the trail quickly.
