Title: Hard to Find Better
Review: I use the K&N oil filter on my 2007 Ford Focus along with Castrol Edge and have found the combination of both, increased my mpg, little pricy but have an oil change every 5k miles instead of 3k miles as recommended by local mechanics, to off set the price. Purchase the K&N through Amazon and find they offer the BEST price and free delivery with over $25 purchase.
