    • When you bolt on a K&N 57i Performance Induction Kit, you will see immediate results. The K&N 57 Series Air Intake replaces the restrictive factory air box with High-Flow air intake technology and a larger air filter, allowing more horsepower-boosting cold air flow to your engine. It will feel like a whole new beast is lurking under your hood.

    The K&N 57i Performance Air Intake is designed specifically for your vehicle based on your engine's characteristics and the available space under the hood. This careful custom tuning gives you increased power throughout the entire RPM range. Plus, the larger air filter on the K&N 57 Series captures and holds more dirt than the stock filter, making it last up to 100,000 miles before cleaning. Cleaner air means better performance from your engine, as well as a longer lifespan overall. Plus, the K&N Air Filter is washable and reusable for the life of your vehicle.

    Each K&N 57i Performance Induction Kit includes all the high-quality adaptors and mounting hardware you need for simple, bolt-on installation, and is backed by a 10-Year/Million-Mile Warranty.

    A definite improvement, mileage better and definitely a much more responsive when accelerating or stomping the pedal while cruising! Installation was easy, but the parts supplied were kind of cheesey. Namely the metal u-shaped bracket, it only provided support and the tube rattled around in it, not a good fit. easy fix with some cheap foam weatherstripping for screen doors, but still, expected a bit more from K&N.

    Not bad on install, instructions vary from yr to yr I understand that. I guess it has helped fuel economy, hard to say on performance due to the August heat.

    The product came in very quickly. Everything was present as stated in the description. After installing the product in my 1999 Toyota Corolla, I noticed a significant difference in the performance. My acceleration and torque was improved, as well as the sound. I would highly recommend this product to anyone who wants a noticeable upgrade for an affordable price!

    Does not seem to be improving my performance. I still do not know that i have all the pieces (i.e., other factors in place). This was just one step for me.

    This kit works beautifully in my 1.8L 2007 Toyota corolla. Not only does it sound good but it also helps the acceleration.

    I just got my new 57I Intake installed on my Ford Focus. It sounds much louder, and noticeably faster out of the block. Not too bad to install, I'd say it took about an hour. It's maybe not as flashy as some of the other intakes, but K&N makes a great quality product.
