Improve Horsepower. A K&N 57 Series FIPK Replacement Intake Tube and Filter Kit will improve the airflow into your Mustang's engine for more power and better gas mileage all while filtering out harmful power robbing particles. This K&N kit replaces your 5.0L Mustangs restrictive stock intake tubing and paper filter element while retaining the factory air box for impressive HP and TQ gains.

No Tune Required. Unlike other Cold Air Intakes on the market for the 5.0L V8 Mustangs the K&N CAI does not require a computer re-tune. The engineers at K&N designed, tuned, and dyno-tested this cold air intake to improve your Pony's power using the stock tune.

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. 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.

Washable, Reusable Filter. K&N designed their high flow 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.

Straight Forward Installation. The K&N FIPK Cold Air Intake Kit is designed to install easily with just basic hand tools. No extra modifications or special tools are required for proper installation. All necessary parts and instructions are included.

Recommended Upgrade. Even though a re-tune is not required for operation, AmericanMuscle recommends a custom tune with a Mustang Handheld Tuner to reprogram the vehicles computer (ECU) to get the best performance possible out of this cold air intake.

CARB Certified. Best of all this K&N 57 Series FIPK Cold Air Intake is 50-state smog legal under Carb EO# D-269-48.

Application. This K&N Series 57 FIPK Modular Intake Tube with a Drop-In Air Filter is specifically designed to fit the 2011 to 2014 GT Mustangs equipped with the 4 valve 5.0L V8 Coyote engine and does not require re-tuning the vehicles computer for operation.

Hello, i was thinking of gettig this with either the Airraid or the C L body spacer. Will that fit together and not be an issue?

will the intake tube have connections for the factory sensors? I am not worried about the sound tube connections.


  • Yes, this Intake tube has ports for the factory sensors.

Which, in your opinion, is the better modular intake tube. The K N or the Airaid product.


  • Both the K&N and Airaid will offer superior airflow. They are both going to be an upgrade from stock and offer a larger tubing size. Though, if you are looking for a new filter as well, the K&N already comes with one where as the Airaid Modular Intake Tube (11-14 GT), item # 383968, ( simply comes with the tube itself.

    Great CARB legal upgrade!

    This is a great upgrade if you're trying to keep your car smog legal in California. Installation was a breeze, although it would be nice if KandN included a firewall plug to eliminate the ridiculous "sound tube" contraption entirely. They do include a cap for the plunger near the fender, which I did not use because I removed the entire system. I had to purchase the firewall plug separately. Performance wise, I'm sure it freed up a few horses on its own. What surprised me the most was the sound difference, even without the sound tube. This added a nice growl that I wasn't expecting out of anything other than an open cone filter type intake. Perhaps it is due to the absence of the "growth" on the underside of the factory intake tube that is probably there to quiet down the motor to begin with (why Ford, why?). Whatever the case, I'm very happy with this part and I can't wait to see how much more power I can get out of this car while staying CARB legal.

    Perfect fit

    I live in California so ordering an air intake was quite challenging. I purchased this air intake and being optimistic, I was very pleased with it. Car idles smooth and has improved get up and go. It goes with the stock air box and easy to install. Great price as well for just about the same horsepower gains.

    This CAI is all that KandN said it would be. Moderate HP and TQ gains, but most impressive is the gain in mileage. I like the way it cleans up the engine bay by removing the totally unnecessary sound tube. This is a nice piece of engineering!

    Cold Air intake from K N

    This was very easy to install. The instructions were very easy to follow.No modification to the car was needed. It arrived in less than a week. Simple hand tools are all that are required to install and a little of your time. Yet another GREAT product from KandN!

    Great quick bolt on for more throttle response.

    This is a very good first upgrade. And you do not have to tune your car to feel the difference. Throttle response is much better. Engine has quicker pickup. Did not notice any sound change, though their might be a little. I plan on doing a tune when the powertrain warranty is up. This item uses the factory air box so you do not have to worry about water leaking thru the hood vents like on the open element air intakes. Very easy to install.

    Worthwhile mod

    I will get right to it, yes this intake did make my 2014 GT more responsive, and the "seat of the pants" dyno confirms it ! I would do this again ! Now lets get to the rest: Easy to install, I like that it reuses the factory air box. No loud intake sound, I like that too Looks also factory, another plus. I only have one suggestion for KandN, why not include a firewall plug so that all of the sound tube can be deleted instead of half of it ? I sent a note to KandN about that.

    K N kit for 2011 5.0

    Intake fit perfectly into stock configuration. All parts needed to install were included. Small change in exhaust tone. Volume of exhaust unaffected.
