Racing down that long black line at Bonneville is dirty business. It’s also one of the most mechanically challenging forms of motorsport there is. Scorching temperatures, a mountain-high elevation and the grit and grime of the salt itself all conspire to play havoc with the best-laid plans of man and machine. Racing at Bonneville isn’t easy. Setting and holding records there is even tougher. And more often than not, those Bonneville racers and record holders challenging and beating all of this rely on K&N, and have for years.
     Denis Manning’s record-setting BUB Enterprises #7 streamliner, the fastest motorcycle on the planet, uses K&N filters. K&N is the overwhelming choice at Bonneville, fit to everything from the smallest 50cc machines right up to the hard chargers and their blistering 300-plus mph speeds. And every one of those K&N filters used at Bonneville is the exact same K&N filter that’s sitting on your parts shelf right now. K&N performance, filtration and enhanced flow is the same for everyone across the board. Bonneville racers and street riders alike get the same thing, and those K&N Filters perform equally well streaking down that black line at Bonneville or cruising over the blacktop on Main Street, U.S.A.
     Deceptively simple in appearance, a K&N Filter is actually a pretty complicated and sophisticated performance part. Made right in Riverside, California, each filter undergoes more development and testing than you could imagine before it’s released for sale. The size of the filter elements, even the number of pleats for the multiple layers of specially impregnated cotton gauze that’s used, is all carefully planned, studied, tested and re-tested until it’s right. And even in these days of robotics and hands-off manufacturing K&N still employs a sizeable workforce whose job it is to hand-count each pleat in a new production run of filters making sure that every K&N Filter put in a box is exactly the same as the one originally approved in the K&N test lab. No exceptions. And everyone, racers and street riders alike, gets the same thing. No exceptions there, either, and none needed.
     There isn’t a V-twin built–stock Harley, Big Dog, AIH, or an all-out custom–that can’t have one of those K&Ns filtering its air and oil. And those K&N Performance Oil Filters are every bit the equal of the High Flow Air Filters. A K&N Oil Filter is “race spec,” providing 20- to 30-percent more filtration than an OE-replacement. They use a special resin-impregnated Synthetic Media for improved filtration, better flow and less pressure drop and that Synthetic Media won’t break down filtering synthetic oils. There’s a heavy-duty steel body for a higher burst point, there are pressure relief and anti drain-back valves and K&N has even included a handy 17mm hex nut right on the end for easy installations and removals. That nut is cross-drilled for safety wiring and K&N pre-lubes the base gasket for a leak-free seal.
     And all of this is available to everyone–Bonneville racers and street riders alike. It’s available directly through Drag Specialties and it’s all in the FatBook so take a look. The fastest guys on Earth do.
