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....

Seems good to me (or I wouldn't have bought it), but I cant tell how much power improvement I'm getting (partly because it's a new car and I don't have much experience with it prior to getting the K&N filter).

For the past 18 years I have used K&N air filters in all my vehicles. Currently, I own a 2010 Acura RL in which I installed the correct corresponding K&N filter two years ago. Recently I purchased a 2010 pre-owned Lexus LS 460 and on November 20, 2013 I had two K&N filters intalled in this vehicle. As with past vehicles, I am looking forward to better performance and improved gas mileage in these two vehicles. SGFrederick
