Improves Horsepower. Now you can improve your 2013-2014 Shelby GT500 Mustangs performance with a K&N Drop-in Replacement Air Filter. Simply replace your stock restrictive paper air filter with a new high flow K&N air filter and feel an increase in horsepower and acceleration while still providing excellent filtration.

Filters out harmful contaminants. The K&N Drop-in Air Filter filter's out harmful contaminants with it's unique layered design. K&N Air Filters are made up of layers of specially treated cotton gauze that are sandwiched between two epoxy-coated aluminum wire screens for durability. K&N uses a specially formulated grade of oil to treat the cotton gauze layers which causes a tackiness throughout the cotton's microscopic strands creating a powerful filtering media that ensures engine protection.

Reusable Filter. K&N designed their high flow drop-in replacement air filters to be reusable. That means there is no need to buy a new filter every few thousand miles, you can just clean the filter, re-oil it, and save money with a K&N Filter Recharge Kit.

Drop-In Replacement. K&N designed this Air filter to be a direct drop-in replacement for the stock 2013-2014 Shelby GT500 Mustangs air box, with no cutting or trimming required.

I see that this is listed specifically for the 13-14 GT500. On the K N website, it says this part (MPN# E-1993) will fit 10-14 GT500. Can anyone confirm this will fit the 2010?


  • According to K&N's website, this will fit the 2010 GT500 model Mustang. As long as you have a cold air intake that fits the GT500 model, this should be able to work as it is a replacement filter only. For further information please contact K&N for exact fitment.

Does this product come with cleaning instructions and what type of oil to use or not to use?


  • Yes, the cleaning instructions will be included in the box and are also available through k and n directly, you would want to use the k and n air filter cleaner and air filter oil.

Hello, My '14' Shelby GT500 is totally stock and I would like to keep my factory stock tune for now. I was thinking about purchasing this k n drop in filter and the Ford Racing resonator delete tube as a combo. Is custom tuning required? Or would they both work fine with the stock factory tune? Thank you and Im a big fan of


  • The Filter and the Ford Performance Resonator Eliminator Kit (10-14 GT500), item # 50269, ( will not require a new tune. Though, if you do any more modifications to the car, I highly suggest a tuner. Once you start changing the air flow of the vehicle, you will want to get a new tune to accommodate these changes.

    Works as described

    Very easy to install. looks to be much more free flowing that the OEM filter. This removes the wire screen that is inside of the OEM filter.

    K N air filter Ruby red Eleonor louvers

    The KandN filter is what I needed to replace the original one. I got it re-tuned and i gained 30 HP so I'm at 691 HP. I wanted the Eleonor look on my GT 500 and it looks great. It was easy to install and it's the same original color, ruby red metallic. AM is the best !! Keep up the good work !!

    Much improved acceleration on my 2014 Shelby GT500!

    Debated for a while between "Dry vs. Oil". I have used k and n in all my previous cars with never an issue. I purchased the drop in air filter and ford racing resonator delete tube at the same time. No dyno but I felt a BIG difference in acceleration and blower whine compared to stock set up. Fast shipping and excellent service by American muscle!
