"I have used K&N filters in all of the cars I've owned for over 10yrs. They are high quality and give a long service life with cleaning and re-oil every 25,000 miles. I can't say I can feel any power gains compared to factory OEM filter. You may see 3-4 HP over OEM filters which is very minimal. I don't trust most of the open cold air intakes available and prefer using factory air box." —Tim S from Nixa, MO bought a K&N Air Filters for a 2013 Ford Focus.

Ford Man

This is my sixth K&N filter I have purchased. It was a Christmas present for my son so just installed it yesterday. Past results have increased mileage so expect the same.

Excellent performer.
