The air box is connected to the throttle by the air boot. The typical boot is inefficient in routing the air stream as it snakes around the frame and shock before reaching the throttle valve. The irregular shape of the boot produces unsteady and erratic air flow - turbulence. The result is compromised power delivery.
The FMF SNAP™ divides the air passage within the boot into quadrants to increase air velocity by directing the air stream and reducing turbulence.
With improved air flow to the throttle valve, you will experience crisper and immediate throttle response, as well as a boost in the low to mid-range torque.
Installing the SNAP™ is as easy as installing an air filter in most cases and requires no jetting or fuel changes. Drop it in the air boot and feel an immediate difference at the first crack of the throttle with a healthier pull off the bottom. The FMF SNAP™ is bolt on performance!

Over the decades, we’ve seen an amazing transformation in the world of motorcycles and ATVs. The progression of the technology is one of the challenges that keeps us going. FMF was there in the days when the singleshock and watercooled engines were huge innovations and we’re glad to be here now for the aluminum chassis and electronic fuel injection. Our goal will never change – take the most advanced machinery to its limit by building the world’s best performing exhausts. And its a fact, we build every exhaust by hand from start to finish right here in the U.S.
At the end of the day, there is always one major force keeping us motivated–throwing a leg over the bike and heading for the trails or the track. The biggest reward for us is knowing we’re helping our customers get the most out of their riding experience. We still ride every chance we get so we never forget why we got into this business in the first place.
