K&N Performance Air Intake Adds Performance & Horsepower to Your Harley®

57-1126P intake parts

The sum of the parts on the 57-1126P intake is performance and style

K&N offers a full spectrum of filter and intake options for the iconic Harley-Davidson® Sportster. If you want to make both a performance and style statement, the K&N 57-1126P intake warrants serious consideration. Most importantly, the intake will significantly boost the horsepower and torque of your V-twin. The welcome byproduct is that it will also boost the cool factor of your Sporty.

First things first. Performance is king in the motorcycling world, and the K&N 57-1126P intake delivers it in spades. By simply bolting the intake to a stock 2009 1200cc Sportster, K&N’s dynamometer showed an estimated increase of over 8.5 horsepower. K&N does not deal in idle claims, so the dyno chart is included in a link right on the 57-1126P product page.

Everything needed to install the 57-1126P on your Harley is in the box

When you click on the proof, you’ll see that the horsepower gains are consistently higher than the stock numbers across the entire RPM range. This is important to note since many other performance modifications result in horsepower gains only at the highest RPMs and sacrifice rideablilty in the midrange. The K&N 57-1126P puts the power where you’ll feel and use it.

While you are on the dynamometer chart page, you should also note that the torque increase is nearly 7 foot pounds. Again, that is useable torque that peaks at a riding sweet spot of about 3800 RPM. That is the range that will make passing minivans and pulling through corners much more exhilarating. All of this performance becomes an even more visceral experience with the throaty intake sound that the 57-1126P emits.

Installation is straightforward and easily completed in 90 minutes

The 57-1126P intake could not be much easier to install. In fact, the process is typically completed from start to finish in less than 90 minutes. The result is a spectacular display of the unit’s polished aluminum intake tube capped off by the instantly recognizable K&N filter element. The unit offers up effective filtration with its layers of oiled cotton gauze media. Of course, another benefit is that the filter is also fully washable and reusable for the life of your motorcycle. All that is needed is one of K&N's convenient filter recharge kits. And if polished isn't the look for you, K&N also offers the 57-1126 in a flat black look.

The K&N 57-1126P is proudly made in the USA and the intake is street legal in all 50 states. It is covered by K&N’s industry-leading million mile limited warranty. If your Harley is listed below, the 57-1126P is for you. For every other vehicle in your personal stable, consult K&N’s online vehicle application tool to find the filtration solution that suits your needs.
