K&N 57i Series Induction Kits are specifically designed for each different vehicle and will free your car from the size restriction that comes with the factory air box. These economical kits can take a variety of different forms based on vehicle characteristics and available space under the hood. Each kit is designed to provide power throughout the RPM range. The extra surface area of these open-air air filters provide even more airflow at lower restriction than a K&N O/E replacement filter which is always limited to the size of the factory air box. The larger air filter also captures and holds more dirt increasing its service life before a cleaning is required (up to 100,000 miles). The filter is either directly attached to the engine carburetor or throttle body or indirectly through a tube assembly running from the filter to the engine. All adapters are made from high quality materials such as steel, aluminum, silicon or reinforced nylon to ensure long life. 57i Intakes are not legal for use in California and other US States adopting California emission standards.

Customer Feedback

My expectations were very high given my previous experience with other K&N filters installed in my other vehicles. Excellent product that lives up to its promise of increased acceleration & overall improvement in power. Very fast delivery of item too. I received much sooner than expected in double box. Installed in a new 2015 Toyota 4Runner Trail making an excellent vehicle even better if that's even possible Hats off to the folks @ K&N

Since I replaced the stock Toyota air filter with the K &N filter I've seen a slight difference in fuel mileage and horse power. Slight but noticeable.

2014 toyota tacoma 2.7l / 5-speed (Brand Name) exhaust & K&N Intake No. 77-9026KP Has an amazing sound at WOT At hi-way speeds, it feels like I don't have to press the throttle down as hard when driving up and down hills. Maybe slight improvement in fuel economy? I've also been thinking of wrapping the intake pipe with an exhaust wrap for an additional heat barrier, but it might be over kill?
