Increase the performance of your Harley V-Twin with a K&N 57-1122P performance intake system

In the 1890s, bicycle racing was all the rage. The more 'inventive' cyclists started fitting their bikes with crude internal combustion engines, in the vain attempt to gain a little more speed. Most of these early "motorized bicycles" proved quite unreliable, but the idea still managed to catch on. By the turn of the century, many leading bicycle manufacturers were making variations of the motor bike, which inspired two guys named William Harley and Arthur Davidson to build one of their own. Their first motorcycle was completed in 1903, and it featured a 3-hp engine with a leather belt driving the rear wheel. The top speed was around 45-50 mph, but you can bet that was a harrowing experience. Fast forward a century, and your 2008-2011 Harley Davidson Twin Cam 96 V-Twin, 2009-2014 Harley Davidson Twin Cam 103 V-Twin, and 2008 Harley Davidson Twin Cam 110 can manage that speed without breaking a sweat. But if you want your modern Hawg to get up there even faster, then you're going to need a K&N 57-1122P performance intake.

The Harley V-Twin in your bike, makes power just like the first Harley did back in 1903: gas mixes with air inside the cylinders, then a spark plug triggers the detonation. If you add more oxygen to the mix, the explosion will be a lot stronger, which will send more energy (horsepower/torque) through the crankshaft and out to the back wheel. To increase the oxygen level, you need to get more cold air into the engine. The stock Harley intake utilizes a thick paper air filter, hidden behind a decorative chrome cover. This forces the air through a small opening behind the cover then through all of the dirt that has collected on the surface of the filter. By the time it reaches the engine, the air has become warm and turbulent, which significantly reduces its oxygen content and potency. The K&N 57-1122P performance intake on the other hand, virtually eliminates these airflow restrictions, so your V-Twin can live up to its potential.

The heart of the K&N 57-1122P performance intake system is the oversized K&N performance air filter. It's made from multiple layers of cotton gauze and treated with a special red oil that causes the web of cotton fibers to become sticky and attract dirt. Airborne contaminants then stay trapped inside the filter where they can't impede airflow (depending on road conditions, the filter won't need to be cleaned for up to 100,000 miles). The additional air collected by the filter then gets sent directly to the motor through a mandrel-bent aluminum intake tube. This polished K&N intake tube not only looks great, but it helps the cold air to maintain velocity as it reaches the cylinders.

Thanks to this innovative design, the 50-state legal K&N 57-1122P cold air intake provides faster throttle response and an even better engine sound. Dyno testing on a 2008 Harley Electra Glide Classic 96ci also revealed an estimated increase of 12.92 horsepower and 14.71 lb-ft of torque.

With great looks and even better performance, the K&N 57-1122P performance intake system can give your hawg some real grunt. It's also backed by the K&N 10-Year/Million Mile Limited Warranty, so you can rest assured that it will perform for a very long time.
