Product Details

57i Series Induction Kit by K&N®. This induction kit is an easy and inexpensive way to increase airflow into your engine. It replaces your restrictive factory airbox with a free flowing K&N air filter. Increasing airflow will make more horsepower and torque, resulting in better acceleration.

Your OEM air induction system is a compromise between induction noise considerations, underhood space limitations and engine airflow requirements. Replacing that system is an easy way to improve engine performance. Increasing the airflow and air volume into your engine will result in more horsepower and torque and possibly more miles per gallon.

The heart of the 57i Series Induction Kit is the world famous K&N air filter. The kit includes the largest air filter possible for the application, much larger than the size restricted filter that came in the factory airbox. The K&N air filter's increased surface area provides less restriction and more airflow, while capturing and holding more dirt. Depending upon the application, the filter is either directly attached to the throttle body or indirectly attached with a flexible tube.

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 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.

Not The Best
For the price and for what it is its basically a setup created in a garage to create better air flow of course but with the least amount of mechanic work possible. You could literally make a better intake for cheaper. Sure it sounds better but it's not the craftsmanship I'd expect for 200 bucks.

Great Filter Kit For A Classic Saab
The filter and house are both quality items. Installation on my 1988 Saab 900 was fairly simple after I figured out the instructions, which included a diagram that was a bit confusing.

Nice Filter
This K&N filter is pretty good, specially for this motor. It took like 2 hours but not hard just going step by step instructions. And guess what, it works great. I've noticed immediately an increase in throttle response and it actually feels like it gained a couple horses too. Overall, I'm extremely pleased with the results. Best bang for buck deal specialy for my 07 Civic 1.8L.

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!

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.
