Product Reviews

Review part 33-2428

Easy to install. Haven't noticed more power.
Peter Coffee, Walnut Creek, California

Filter installed with ease, had to have special screw driver to undo screws holding the cover. All seems fine, have the same type filter in my 1995 Yukon and it is still clean. Great product. Also have your Oil Filter in the Yukon and have used them for years.
David Schweitzer, Costa Mesa, California

Got it fast. Not the first time buying from this site. I totally recommend.

Got it fast. Love it.

Great product. Drives better and better consumption of fuel.
Pedro Verdejo, Florida

Perfect fit, ran a K&N in my 2006 BMW 530i. (3L - 6 cylinder). Put 334,010 miles on the car and still got 31+ mpg highway. Motor was strong; transmission was starting to go. Will see if I can do better this time in 2011 BMW 535i. Turbo 3L - 6 cylinder.
Ivan Smith, Trussville, Alabama

Well worth the effort and price to get this filter - there's a noticeable increase in HP immediately.
