The K&N 57 Series Generation II Air Intake 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.
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 57 Series Generation II Air Intake 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.271.42 343.31

Installation was pretty easy, product looks great, gained HP, torque, and best of all 2-3 MPG... but threw a check engine light for the mass airflow sensor, truck still runs great though. Waiting on K&N to figure out a fix for it.Was this review helpful for you?

I recorded everything and received everything on time, at the same time, I even got my cold air intake in quicker than they listed it would be there. Everything was right. Easy installment and a happy customer. And customer service was great. Thank you CARiD, and I'm not any competitor or work for CARiD who write dumb stuff just to confuse people. This was my genuine experience.Was this review helpful for you? YesNo(4.5)APPEARANCEEASE OF INSTALLATIONPRICE/VALUEQUALITY2004 Dodge Ram2004 Dodge Ram

Everything went as I hoped for. Easy installation with no issues. Truck sounds exactly the same except for when you step on it, it sounds awesome. I am yet to find out if it improves on my gas mileage. Recommended.Was this review helpful for you?

I was extremely impressed with this product. It only took about an hour to install on my 2011 Ram 1500. The difference it made was very noticeable. The sound coming from the engine is a lot more deep and throaty sounding. Especially from 2000 rpm to 3500 rpm. The throttle is much responsive with this kit and the look and sound overall was amazing. I would highly recommend this kit.Was this review helpful for you?

I absolutely love my K&N cold air intake. Install took me about 3 hours because I had never done anything like it before but I didn't run into any problems. It looks great, sounds amazing, gave my truck a deeper sound, it feels faster, better response and in one day I gained about two mpg. I probably will gain more after a couple weeks.Was this review helpful for you? YesNo(5)APPEARANCEEASE OF INSTALLATIONPRICE/VALUEQUALITY
