No-Toil - SFK15043 - Super-Flo Air Filter Kit KTM 125 250 SX EXC XC-F 1998-2007

Breathe Easy. Ride Hard.
The SFK15043 Super-Flo Air Filter Kit is a complete, high-performance replacement for your OEM KTM filter and cage assembly. Whether you’re ripping a KTM 125 SX through tight corners or pushing a KTM 250 XC-F across the desert, this kit gives your bike the airflow it’s been begging for.

You get a super-strong, high-density polymer filter cage—with no backfire screen—to maximize air intake and performance. Air in means power out. And unlike stock, you’re getting a top-quality, 2-stage, flame-resistant foam air filter that’s specially treated so it won’t hold a flame. Sparks? Heat? No problem—this filter won’t burn.

To top it off, we ditch that boring OEM filter cage screw for the all-new No-Toil “Filter Cage Screw Thingy.” It’s grippy, ergonomic, and delivers maximum holding power so your filter stays put—no more fumbling in the pits.

This dual-stage foam filter is built to handle dirt, dust, and track abuse while letting your motor breathe at full capacity. If you’re serious about KTM performance and reliability, this is the upgrade your bike deserves.
