Product Details

57i Series Generation II Induction Kit by K&N®. This kit improves airflow into your engine. It includes a K&N air filter and a custom designed air intake tube. The K&N filter increases the airflow and the intake tube smoothes that airflow into the engine. The result is more horsepower and torque, and better acceleration you can feel.

The K&N 57i Series Generation II Induction Kit improves intake airflow from the air filter all the way to the throttle body. The system starts with the world famous K&N high flow air filter. K&N uses the largest conical shaped air filter that will fit in the engine compartment. The large increase in filter area over the stock airbox filter results in a huge increase in airflow and a greater capacity to capture and hold dirt.

The filter is attached to a precision molded intake tube that connects the filter to the throttle body. The tube is precisely designed to reduce turbulence and accelerate airflow into the engine. The rotationally molded intake tube is made from interlaced high density Polyethylene, reducing intake air temperature from similar metal tubes. Intake air temperature is further reduced by a heat shield that isolates the filter from the engine compartment. The reduction in air intake temperatures results in a cooler, denser air intake charge and even more horsepower. Some applications may also include an additional flex tube for cold air applications.

K&N uses a dynamometer to design its air intake kits to make the most horsepower possible. But their power figures aren't based on just one vehicle, but rather an average of runs by a number of vehicles. This means repeatable numbers and horsepower claims you can count on.

Every 57i Series Generation II Induction Kit comes complete with everything necessary for installation, including comprehensive installation instructions. All adapters are manufactured from high quality materials such as steel, aluminum, silicon or reinforced nylon, to ensure long life. The K&N filter can go up to 100,000 miles before cleaning is required. And the K&N air filter is guaranteed for one million miles.

Intake
Sounds great. However, can’t tell if there was a power gain. Too many greats in the A class to tell. But it does sound much more aggressive.

Dude. This CAI is legit. I'm no mechanic and I installed the 77 series on my '13 F-150 5.0 in a little over an hour, and that was being really careful and double checking Everything. If I had to do the same install again I'd have it done in under 30 minutes. Can't say much yet about increased power cuz I only drove it 10 minutes to make sure it ran. Sound Roar Sounds like a giant taking a *** off something. I run Flowmaster 40 single in dual out with resonater delete and the Coyote sounded great before but now you don't hear just the exhaust, you hear the V-8 Engine. A lot more muscle car feel just with this install. Worth every penny.

Awesome!
The hubby loves it. Definitely quicker get up, I’m not sure about loudness due to having a flowmaster exhaust already installed. Installing was quick and easy. I definitely recommend purchasing this cold air intake!

Cold Air Intake Install
This was a quick and easy change from stock to new cold air intake. The instructions were on point.

Fantastic!
This is the first time I have bought a full K&N intake kit. I've usually just replaced the filter with the stock intake system. Yes, I've noticed a difference here and there. It may not be horsepower gain, but there was definitely an increase in throttle response. I have a 5th Gen Camaro SS. After installing this intake system, my goodness, what a difference. Throttle response has increased. Horsepower gain, well I can't determine that, however, I'll take K&N's word for it as they claim an almost 20 horsepower increase. Toruque, again, I can't prove how much it has increased, however, I for sure can feel the increase. To me, the best part is the engine noise. The engine is stock. With this system in place at high RPMs, you can hear that sweet 6.2L engine in all its naturally aspirated glory coming from the engine bay inside the car. It's amazing. This intake system is well worth the money and has now put an even bigger smile on my face.

Fits Easily and Sounds Great
Fits easily and sounds nice and loud in my 2003 ram 1500, only issue with this filter is that you have to drill a hole into the new filter tube for the o2 sensor. Other than that its very basic and easy to install
