Description
Improves Horsepower. Now you can improve your 1996-2004 GT/Cobra, 03-04 Mach 1 and 01 Bullitt Mustang's 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 filters out harmful contaminants with its 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.

Drop-In Replacement. K&N designed this Air filter to be a direct drop-in replacement for the stock 96-04 GT/Cobra, 03-04 Mach 1 & 01 Bullitt Mustang's air box, with no cutting or trimming required.

I recommend this if you are on a budget

I recently replaced the stock filter with this drop-in unit from K&N and have noticed a sizable difference in throttle response and exhaust tone. I recommend if you are on a budget.

So how exactly is this a drop in filter? Does this fit in your factory ford factory air box or does this attach on its own like a cold air intake..? I'm just curious if it does go in the air box how does it attach and will it stay in place?

  • It does go in the existing air box as a direct replacement for your disposable filters that you origionaly used. It clips in place with the same tension bracket that held the disposable filter in place. This is a good reusable filter if you want to just replace that. I used one in my 2001 GT for almost 5 years, it's a good product that I suggest to any Mustang owner who cherrishes their pony. If you're looking at this as a performance upgrade however, I strongly urge you to invest a little more and get a true cold air intake such as the BBK one ( http://www.americanmuscle.com/bbk-coldair-intake-96-04gt.html ) or something comparable. I can feel a definite increase in performance since the change and it was easy to install. You still get the reuable cloth filter, but moving the air intake to your fenderwell makes a noticable diffrence. On top of that, the chrome finish or one of the others with a matt black look awesome under the hood. You can see mine if you look at the customer photos and find the yellow Mustang. I installed it in the parking lot at work on my lunch break! Easy peasy!

Is it washable and reusable?

Dman3551 Year: 2001 Model: GT

  • Yes, you can get the recharge kits at most auto supply shops. You may also want to get a second filter that you can clean and have ready to change out to shorten your down time when you service your pony. Enjoy your new filter, I know your pony will.

    Great product!

    Great product, Better flow then original paper filter... And my ride breathes a little easier now. If your on a budget like me and can't afford to spend 200 bucks on a cold air intake. This is the next best thing.

    Don't bother with a CAI

    Don't bother with a CAI, this is the same thing for $150 less and less chrome. It may not look as nice, but if you remove the stock filter and the stock restrictor, you have the same exact thing as a CAI. And K&N is the best.

    Boosted K&N filter upgrade

    For my Tork Tech Terminator project I used a bone stock 03 Cobra intake, including paper filter. Made 405hp/404tq. Swapped out for this drop in filter while still on the dyno, and made 412hp/408tq. Not bad for such a cheap upgrade.

    K&N

    I recently purchased an almost stock 2000 GT. Was not happy with how it sounded, responded when I stepped on the gas. After looking at the old paper filter I realized the problem. It was disgusting(dirty). Put in this K&N filter in 10 minutes. My GT sounded like I put new exhaust on it. Very responsive when I step on the gas. Highly recommend this product.
