Built for performance and show utilizing the highest quality components, the K&N 77 Series High-Flow Performance Air Intake is a free-flowing mandrel-bent aluminum tube induction system designed for Trucks and Sport Utility Vehicles. 77-Series air intakes come with K&N's Million Mile Limited Warranty. K&N intake systems replace your vehicle's restrictive factory air filter and air intake housing. K&N intakes are designed to dramatically reduce intake restriction as they smooth and straighten air flow. This allows your vehicle's engine to inhale a larger amount of air than the OEM air filter assembly. More air means more usable power and acceleration throughout the engine's RPM range. The filters on these kits are washable and reusable. Most of our intake kits are relatively easy to install using tools commonly available (see installation instructions). This 77 Series Air Intake cannot be sold in California. It is not legal for use in California or other states adopting California emission standards. Check the K&N catalog or website vehicle parts search for specific CARB status.

Outstanding product and customer service! Once I installed the new air filter into my Chrysler minivan, I could definitely tell that the engine was running stronger. This was sort of a confirmation because I had purchased a K & N filter earlier for my Toyota Tacoma and was (am) very happy with the increased performance. I told my brother in law about the filter and he bought one for each of his two vehicles as well. Great job folks and best wishes for continued success!

Based on a long history of using K&N, I replaced my son's Toyota Tacoma air filter. It was very easy. I am less than a month on the new air filter so can't comment yet on how well it is working.

WOW...what a difference having replaced the stock Toyota air filters with K&N replacements. I used the plural because the Lexus LS460 has 2 separate air filters. The car is an absolute BEAST having easily raised the horsepower to over 400+ while maintaining similar fuel economy. I'll probably get better MPG when I stop stomping on it just to feel the POWER! Replace the stock chip and void the warranty...absolutely no way. But changing the air filters (and NOT VOIDING the warranty) seemed way too easy. I was so impressed I bought new filters for my wife's GS460 and our Toyota Tacoma 4.0 V6. Both have dramatic increases in power and fuel economy albeit, she's having problems with not stomping on it as well. Who ever came up with this idea for passenger vehicles kudos! Can you do the same thing for HVAC units? I want to feel the polar blast save energy and make my wife a human pop sickle! With GREAT admiration....
