Features & Details

  • Filters Out 99.9% of Harmful Contaminants
  • 100% Synthetic Micro-Glass Media
  • Silicone Anti-Drain Back Valve
  • Thicker Canister for Extra Strength
  • Royal Purple Part# 20-400
  • Fits 1994 to 2004 V6 Mustangs
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 1994 to 2004 V6 model Mustang.

          Fits right on. Great Construction Quality.

          Not much else to say, its an oil filter. It fit right on snug. From what I can tell so far in my first use of this type of filter, it's doing its job.

          Thumb's Up for RP

          Read all positive reviews on various websites about this filter! Should be able to accommodate my once-a-year OCI with the Mustang. Thicker canister shell, silicone ADV, and glass media---a super deal for the price! Thanks, AM!

          Royal Purple Oil Filter

          Great product, took me 20 minutes to change my oil and I could immediately tell a big difference. Would never go back to any other brand.

          Necessary Upgrade

          Back in the day, Royal Purple was known for additives and being the top in their field. Now, the same applies to their maintenance fluid. Cold starts are much easier on my Mustang and it runs like a mean machine from start to finish.

          Great Oil Filter

          It's a great oil filter when paired with royal purple oil, I automatically noticed the difference when I ran my car with it. It just gives you the confidence that your car is running on a great quality oil with a great quality filter

          One of the best filters money can buy

          These filters are truly excellent, I talked to a Royal Purple representative on the phone to get all the filtration data for the filter before buying it and the high filtration efficiency at particle sizes of 15, 10, and 5 microns are a big selling point for this filter. I have oil analyses preformed on my used motor oil and I found that with these filters I have been able to extend my filter change intervals significantly. I normally changed my filter at 4K and my oil at 8K with other premium filters, but with these filters I'm able to run one filter for the full 8,000miles when running Royal Purple motor oil.
