Description
Improves Horsepower. The K&N "Fuel Injection Performance Kit" (FIPK for short) Air Intake Kit completely replaces your stock 1999-2004 3.8L & 3.9L V6 Mustang's restrictive stock factory air box and paper filter. This FIPK Cold Air Intake features a high flow K&N filter assembly and intake tube for a noticeable increase in horsepower and acceleration, all while still providing excellent filtration.

Filters Harmful Contaminants. The supplied K&N Filter successfully filter's 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.

Straight Forward Installation. With commonly available basic hand tools, the K&N FIPK CAI requires no extra modifications for a simple, straight forward installation.

Application. This K&N FIPK Cold Air Intake is specifically designed for use on 1999-2004 3.8L and 3.9L V6 Mustangs.

  • This K&N Cold Air Intake does not require a tune for installation. That said, you'd obtain maximum gains by combining the CAI with a custom tune.

    A cold air intake is a easy way to get a decent amount of horsepower, but there is far too many to choose from. I used to have BBK and it was alright. After putting this on you can tell where your money goes. K&N is the best. Gave me more response and slightly more pull.

    Well Worth It

    I have a 40th Aniv. Mustang V6, so naturally I wanted a V8 and figured this would help me on my way to getting close. It deff added a big increase of horsepower and my car sounds much deeper. The whistle of course is always a nice touch too. Only problem i have with it is that it makes the car really jumpy at times when you let off the gas and stay at an inbetween speed. But overall well worth it and a great part to choose. Thanks AM.

    High quality intake

    Wow, how cool! Fits my 2001 V6 like a glove. I noticed a slight gain in power, nothing too big. You can hear a sucking sound inside the car when you step on the gas, but the sound is nothing to rave about. BUT, hard revs in neutral produce a very cool sound, similar to a turbo. A little expensive, but you pay for a good product. K&N says it's a 6.something HP gain. So four stars for price/HP ratio.

    K&N CAI for 99-04 V6

    I've had the CAI on my 2004 3.9L V6 since Sept 2009. I noticed an immediant difference in response, sound, and efficency. I went from 27mpg to 29mpg.

    worth the money

    i took a while to decide on and intake, but ended up going for the K&N. so glad i did, when you make quick shifts and floor it at high revs you can really hear it suck in the cold air in and whistle. Install was relatively easy, took me 2 hours but i didn't want to mess anything up. Don't waste your time with the others, just go for the best.

    It works

    Bought this for my 04 Mustang. I run the 3.9L/238, not the 3.8L you comminly see. Took bout an hour and ahalf. Definately see a difference. Enigine sounds more like a v-8 and will get up and go. The only thing is this is built with tight tollerances.

    Not CARB Legal for 3.9L

    I had to remove mine after trying to get it to pass CA smog. The guy insisted that even though the 3.8L and 3.9L are almost identical, and they have the same part number stock exhaust manifold part numbers, that because K&N did not certify it for the 3.9L it was not legal. CA Stangs BE FOREWARNED. Other than that, it fit well, was easy to install and produced descent gains.
