From the first time I drove my 2002 GMC Envoy after installing the K&N Air Filter, I felt smoother, faster acceleration and after the third tank of gas, I see visible increase in fuel economy of about 1-3 miles/gallon. Was it worth the cost of the new filter-absolutely!! K&N makes great products. Go for it!
