This is my second filter. I ran the first one in my 2110 Tundra from the day I bought it in 2010. I got better gas mileage and more power, I'm sold on this product. I took my truck in to my mechanic to get some work done and for some reason this time he noticed the K&N air filter this time and threw it out and when I picked up my truck he told me to never use one of these again, it would ruin the sensors inside the air flow duct. I told him it had been in there 7 years and never had any problem, worked great. Well, got my truck home and I pondered this for a couple of months and called K&N customer service and voiced my concerns about what I was told, and because I had bought my wife a new Corolla in 2013 and put a K&N air filter in her car when we first got it home. They were very helpful and very knowledgeable, and set my mind at ease. Point of the story, best air filters, bar none, on the market today. Very happy customer, and one for life. Thanks for great customer service and a great product
