After two years of ridiculously hard riding, rev-limiter burnouts, and repeated wheelies we thought we had our 1200 Sportsters at their peak performance. After several referrals to change our Screamin' Eagle Performance Filters out for K&N Charger Intakes, we finally gave in. First impression was that the K&N Charger system looked very cool and added to the performance look of the bikes. We were worried that aside from its good looks the protruding tube and filter might get in the way of our riding maneuvers.

The installation was very simple and only required some very basic tools and very little mechanical knowledge. Everything fit perfectly and had great finishes that matched the bikes factory equipment.

After installation we noticed that the tube/filter does not protrude out from the motorcycle near as much as we thought and fits the profile of the bikes perfectly.

On the first ride we could tell an immediate difference in initial throttle response and torque off the line. Continuously pushing the motor at extreme temps through burnouts or into wheelies generally produced less and less throttle response/power as the bikes reached maximum operating temps with Screamin' Eagle intakes. The K&N Charger Intakes have eliminated those effects and power loss felt at max operating temp giving us longer intervals to perform our v-twin motorcycle exhibitions!

We ride and push our bikes beyond the limits that most riders will ever face on the road. Don't let inferior performance products keep you from enjoying the throttle response and power you deserve from your motorcycle! I know we won't...K&N for life!

I have used K&N products for several years as a ship's engineer. I am now retired and still own the 1988 Harley Davidson FLST I bought new in '87. I also am still using one of the first Screamin Eagle CV carbs. No one makes the correct air filter, so I went back home to K&N for a universal filter that I knew would not only deliver the air flow necessary but would look good as well.

I installed the RF-1020 on my new (at the time) 2005 F-350 Harley Davidson Edition with the 6.0 diesel. The fuel mileage went up by 1.5 miles per gallon after installing the kit. Now with 352,500 miles on the truck it averages 19 MPG on the highway and still has the original RF-1020 on it. I clean and oil the filter regularly and I expect it to last forever. The chrome cover fell off the filter almost immediately but that didn't seem to make difference in performance. Thank you for a great product!
