"this filter is the best. there are similar types out there & they may cost less; but, K&N does the job and never needs replacing - basically. for that reason, even if you were to buy stock filters you'd probably spend the same over the life of the car/truck - although the time saved shifts the scale to K&N." —Richard J from Hartsdale, NY bought a K&N Air Filters for a 2003 Toyota Corolla.
"great product, with superfast delivery. You can definately notice air flow difference and increase in hp." —Timothy R from Clearwater, FL bought a K&N Air Filters for a 2003 Toyota Corolla.
