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.

Works just as promised.

I've been using K&N filters on my motorcycles, cars, and trucks for years. They always help the engine breathe more efficiently and give me slightly better gas mileage. They're easy to clean when needed and last the life of whatever vehicle or bike I put them on. Don't mess around - these filters are superior to anything else out there.
