Review on Engine Air Filter Washable Reusable Replacement Parts in Filters by Tim Crowder

I've been using K&N air filters for years and love how they save me money. When my daughter asked what service her 2013 Toyota Corolla needed, one of the things I suggested was a K&N air filter. She asked what was so good about a filter. I said it could improve fuel economy by 10-15% or acceleration depending on how she drives her Corolla. She wanted to know how long it would take. I said I wasn't sure but I had a K&N air filter in my 2002 Ford E-150 for over 13 years and over 230,000 miles. Then I read that others have lasted up to 3 million miles so I can't tell you exactly how the filter will last. A month later and now on the holidays, the whole family around my daughter noticed that their car is working very well now.
