99.9% Filtration Efficiency. Royal Purple Extended Life Oil Filters use a 100% synthetic micro-glass screen-backed media for superior particle removal with a 99.9% filtration efficiency at 25 microns all while not sacrificing flow.

Anti-drain Back Valve. Royal Purple filters feature a unique silicone anti-drain back valve that prevents dry starts by eliminating oil drain back during shutdown. Silicone outlasts and outperforms standard nitrile rubber in both extreme hot and cold oil.

Superior Construction. Royal Purple Filter housings have a much thicker shell wall for additional strength to provide security against a puncture from road debris. Along with a heavy duty rubber base gasket and steel back-plate to ensure against leaks, this oil filter endures a much higher burst strength than standard conventional filters.

Application. This Royal Purple Extended Life Oil Filter is specially designed for use on the 1996-2010 GT, 1996-2004 SVT Cobra, 2005-2010 V6 and the 2007-2014 Shelby GT500.

    I wouldnt! RP Wont back it!

    I wouldnt touch this with your car! Only Motorcraft Filter or Ford Racing Filter!! plus they are better! I Ran Mobil 1 in all my cars and never had any problems... The one time I change because of reviews and claims of hp boost, I put Royal purple in my 05 Roush with 30k mi..... well I got blow by and lost 2qrts of oil which 'burned' up (How? who knows because Royal Purple.. shouldnt burn up esp on 30k mi motor) but I have no leaks and I had full oil! but loosing those 2qrts and the blow by caused me to drop 3 cyl!! from loosing 2qrts of Royal purple! I would never ever recommend or use their products again! $8k later for a new motor! Royal purple makes all these claims but they wont back it up I had to pay for my own motor! I would never ever use Royal Purple again! For Oil: Mobil1!! or AMSOIL (if u have$) for oil filter: Motorcraft or Ford Racing on cars other then ford I use K&N.

    Royal Purple exceeds OEM

    With the anti-drain back valve it eliminates dry starting your engine when serious damage could occur. Using a standard filter without this feature could actually void your warranty should you develop cam phaser or bearing problems (thanks FoMoCo). All comparisons point to the Riyal Purple filter being better than the competition in every aspect. This filter far exceeds OEM & I've switched to using them on all my vehicles where applicable. Thanks to American Muscle for providing them along with great prices & fast shipping.

    Nice price and quick shipping

    I ordered (2) of these filters for my 2006 Mustang GT on a Saturday and received them on Tuesday. The filters are nicely priced and when installed with 5W20 Royal Purple Motor Oil, lets you extend the time between oil changes.

    Royal purple = best

    Not much can be reviewed with an oil filter, but the fitment was perfect and it is not leaking any oil out from the seal. Easy installment , have used this in the past and seemed to increase oil life . I would and have told a friend about it. AM good service and free shipping can't beat that.

    The best

    I know most people just pop in their oil filter and forget about it until it needs changed, but this filter never caused me any worries or problems and that makes me happy.

    Great product

    Seems at least as good or better then k&n that costs $5 more or any other filter I have ran. I have run royal purple for 4 or 5 years now in my 96 GT and over a year now in my 2000 gt show car.I was happy to see they came out with a filter and at a great price now that I have put some miles on my 96 and I am very happy with new filter. I am going to be buying another one for the show car when I change the oil.
