    Filters out harmful contaminants. The supplied K&N Filter successfully 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.

        3 Top Rated Questions

        Will it fit with a Steeda 3point strut tower brace?

        • We have not used the K&N FIPK Cold Air Intake (03-04 Mach 1) with the Steeda three point strut tower brace. I do not believe they will work together just by looking at where the intake sits at the mounting points of the strut tower brace.

        Does this fit an aftermarket throttle body?

        • The K&N FIPK Cold Air Intake will fit all aftermarket throttle bodies for the the 03-04 Mach 1.

            The KandN Cold Air Intake matched up perfect. Plus intake did not delete Ram air duct. The power gain is immediate I was able to tell a difference. Nice!

            So far so good

            Looks good, hoping for a little less restriction out of this. Hose clamps could be a bit larger for install. Only bad part is the connection between the new housing and the shaker tube. It looks weak and does not install too easy. I left the MAS screen out for install. Also someone said the shaker intake air is not filtered by this set up?? It definitely is.

            Worst mod I've purchased

            Car will constantly die after poping it in neutral above 50mph, so much for spending 300$

            Shaker Filter?

            This took a complete day. All the K and N rubber connections should be set in the sun and get your soapy water ready. The fit and finish for the shaker is a mess. Hole not matching factor hose very well. There are tacky gaps, but with this system air is unfiltered to the shaker. Yep. While your in this deep clean your MAS and throttle body.

            Mach 1 K N CAI

            I am very pleased with the research kandn did with their cold air intake for the 03-04 Mach1. Compared to others, the KandN kit fit perfectly with no rubbing or clearance issues. I'm happy that they have a bracket to support the air filter end of the intake, they actually provide you with dyno proven numbers specifically for the Mach1, and the shaker hook-up lines up great to their metal air filter shield, not a flimsy $0.10 plastic one. Looks great, sounds great, and you feel a difference in the higher rpm range. Best quality and performance for the price.

            Great product!

            Looks great. Cleans up the engine bay nicely. Seems to have helped my gas mileage and gotta love the sucking sound. Only complaint was the hose clamp that connects the tube to the mass air is to small. I could only get it to grab one tooth and it stripped it out. Had a bigger one laying around and it worked fine. Is it that big of a deal to just put slightly larger ones in the kit?

            Great product

            I am very satisfied with this product. Fit and finish was excellant except one part. The ram air connection fit was off. I spent less that an hour installing the main components but several hours trying to hook up the ram air to the filter housing. Was not able to get a good fit without some "customizing" .

            And must have on the mach

            Looks outstanding. It actually surprised me that the kit had a new filter cover. Fitment was kinda hard due to short hose clamps. An extra half inch would have been nice but it work with some elbow grease and screw driver. As soon as I started the car I heard a difference in exhaust. I even heard the filter ducking air. GREAT PRODUCT.

            Awesome Product!!!!

            Make sure to leave MAF screen in when installing or you will be taking it all back out... Performance may gain a little due to the larger filter but really cleans up the engine compartment and looks great. Would highly recomend..

            K&N RAI

            I really like this. Super easy to install, looks great under the hood, and you can really here this baby suck when you get on the throttle. With an exhaust and Bama Performance tune, you will really feel the difference. I highly recommend getting this over the JLT RAI, This is a one piece, where the JLT is not. I feel like the JLT is cheaply made and the K&N also seems to fit better (no scraping the hood). Two thumbs up.

            I have a 2003 Mach 1 and this sounds so nice it sucks air really hard to where you can hear it! The hp gain really isn't that noticeable due to other upgrades but I'm sure it works just fine by itself

            Quality for your money

            Installation time was around 2 hours and I am only a novice when it comes to automotive mechanics. Anyone shouldn't have any trouble installing this kit at home with minimal tools. Fitment was good and the install was smooth. Marginal power gains were noticed but I have yet to get the car tuned so the power gains will increase with a tune I'm sure. The only issue I have had is when I'm going between 50-65 mph in 5th gear and put the car in neutral the engine rpms drop down below 500 and sometimes the engine will even stall. Im not positive it is the kit however the car did not do that until after the kit was installed. Maybe with a tune this will not occur. Definitely a good choice for 03-04 machs. They just need to come out with a chrome version now!

            Good intake, but a couple problems

            pros: nice gain of power, mpg, and liked the sound. Cons: had some trouble getting it to fit, and if i put my car in to neutral while coasting down a hill it sometimes causes my car to stall. ovarall it was good for the price, and it leaves the shaker hood funcitional.

            I have this on my 04 Mach1. It installed easily in less than 30 minutes and works well. I noticed a power difference over stock with it and it helped out my fuel mileage a little too.
