    Review & Install Video

    This is K&N Series 57 FIPK Intake with a Drop-in Air Filter, and it's basically a form of an aftermarket cold air intake, but it reuses stock air box from the 2015 and newer GT Mustang. This intake does not require a tune, and it's a good way to keep the cost down, since this is a no-tune required upgrade, and it reuses a stock air box, so it's a lot less expensive than your other options. And since this is no-tune required, it means that you can purchase this now and install it for a better performance and better looks under the hood and add a tune later on to really reap the benefits. The install for this is gonna be easy. It's a one outta three wrenches in the difficulty meter. You can plan on spending about an hour to get this installed.So the good thing about a no-tune required intake is obvious, it doesn't require a tune. So you get the benefits of a cold air intake, the sound and the looks, without having to pay for a tune as well. But just because this intake doesn't require a tune doesn't mean that you can't pair it with a tune. In fact, you get the most performance benefits from the intake when you do pair it with a tune. Without a tune, you're looking at gaining a couple of horsepower. And we're gonna put the car in the dyno in a minute and test this intake with a tune so you guys can see the power potential here.The K&N is gonna come with a few pieces. You'll have everything here that you need for the install. You have your air filter, your inlet tube, clamps, an adapter for the filter, and a coupler for the filter as well. And it's gonna come with all the necessary hardware that you need to get this intake installed. You are gonna reuse your stock air box, which means at the end of the day that you have the performance benefits of the factory setup: the enclosed air box and the direct cold air feed in the grille from outside of the car. And the new K&N filter will help you get around the restrictions of the stock paper filter, so you reuse what's good here and upgrade where the factory setup is lacking.Taking a look at some of the components of the intake, the air filter is an oiled reusable filter, and it's made from layers of cotton gauze and screens that are epoxy-coated for durability and filtration. The oil is used to treat the cotton gauze to give it a tackiness and give it the filtration abilities that it needs. What's nice about a reusable filter is that you can clean the filter when it's dirty and reinstall it, and you don't have to worry about having to purchase a new filter every time. The intake tube is a black plastic tube, and this, plus the fact that you reuse the stock air box, is gonna be the biggest differentiator between this K&N intake and the Series 69. The Series 69 has a polished aluminum intake tube, and that's gonna look totally different in the engine bay. As far as price goes, since this doesn't include an air box like a traditional aftermarket cold air intake would, it's a more budget-friendly option. You can expect to pay close to $170 for this intake, which is less expensive than any other cold air intake option currently.When it comes to the install, you're looking at an easy install and a one outta three wrenches in the difficulty meter. You can plan on spending an hour here, and you'll need a basic socket set and a flat head for the push pins. Like I mentioned earlier, the intake will come with all of the items that you need to complete the install. You don't need to remove the factory air box to install this intake since you'll be reusing it. You just need to remove your intake tube, disconnect any connections to the tube, and loosen the clamps. Swap out that tube for your new K&N inlet tube and reconnect your old connections. Next you'll need to swap out your factory air filter. Just open the box and replace the paper filter with the K&N filter. Now that we have this intake installed, let's get this car in the dyno and compare some numbers. We spun the car in the dyno before the intake was installed, and we saw numbers of 382 horsepower and 359 foot-pounds of torque with the stock intake and no tune on the car. After the intake was installed and a Bama tune uploaded, we saw numbers of 407 horsepower and 387 foot-pounds of torque. Makes for a peak gain of 25 horsepower and 28 foot-pounds of torque. And like usual, peak gains are always nice to know, but what's really important are the curve gains. The curve gains are the gains that you're gonna notice in your daily driving. You're looking at 33 horsepower at 5,100 rpm and 38 foot-pounds of torque at 4,300 rpm. That's gonna do it for this review of the K&N Series 57 FIPK Modular Intake Tube with a Drop-In Air Filter for the 2015 and newer GT. You can always check it out more online right here at

    I already have the K N drop-in air filter. Can I just buy the intake tube without the filter?


    • We do apologize but the K&N Series 57 FIPK Modular Intake Tube w/ Drop-In Air Filter for the 15-17 GT will not be able to be separated from the full kit. We will only be able to offer this cold air intake including the drop in filter.

    Is this competible to 2018 Mustang GT?


    • The K&N Series 57 FIPK Modular Intake Tube is designed to work with the 15-17 GT models only and will not fit a 2018 GT.

    397710 do you know what the diameter is on the Intake tune for this item


    • The K&N Series 57 FIPK Modular Intake Tube will have a different diameter depending on where the measurement is taken, as this is tapered. The minimum reading will be approximately 4". No tuning changes should be made to accommodate for this intake, as this is installed after the MAF, all intake air has already been measured by the MAF, and changes will cause issues with the air/fuel ratio.

    is it a requirement to block off the sound tube or will everything connect to intake tube?


    • The K&N Series 57 FIPK Modular Intake Tube w/ Drop-In Air Filter will come with a cap to block the sound drum in the sound tube - the intake will not have a provision for the sound tube.


    Helpful (0)

    Does this also include the pieces for the sound tube delete or would I have to order that kit as well? Thanks!


    • The K&N Series 57 FIPK Modular Intake Tube w/ Drop-In Air Filter will include the sound tube delete block off which you will not need to purchase the additional kit from this cold air intake.

      Great easy modification.

      Received item on scheduled date. KandN kit made of durable material and had all parts needed for easy installment. Must have mod for someone not willing to add a lot of horsepower and have to tune. Easy to install especially since I am disabled 71 yrs young. Car breathes much better and has quicker throttle response. Installed it last night and have had a chance to see if it has improved my mileage. Have had KandN on every vehicle I have owned.

      Simple add on but big impact

      Was a simple add on but directly can feel the engine breath smoother and was a perfect completion to my exhaust system as I didn’t want a full air intake change.

      Its ok

      Recently installed the kit. Tube seems to fit well. Filter however is questionable. Seems like the filter housing lid does not latch very tightly. I'm a little concerned there may be air leaking past the lid which means dirt may get past the filter.

      K N intake

      Best intake ever without breaking the bank. Had only one minor issue with the ford performance oil catch can that had previously installed, nothing major, just a hose that needed to be re-routed.

      Great value

      Although my car already had a quality tune I could feel a big difference in throttle response in normal driving mode. I can definitely tell the difference . Gained 2 mph on highway too. I'm happy for what I paid for this product!

      Glad I Went With This Kit

      I have had this intake kit installed on my 2017 GT for a little over a month now. It was easy to install, looks great and is less than half the cost of most other CAI kits. I drove with just this mod for about a week a I could definitely tell a difference over the stock tube and filter. On just daily driver mode I could tell a big difference in throttle response and acceleration, it almost felt like driving in Sport mode with the stock tube and filter. Gas mileage is the same over stock and I'm sure would be better if not for this mod and the cat-back system I installed, I enjoy the new performance and sound to much. If you're like me and don't want to worry about messing with tuning (until needed with a SC kit installed) and want more performance at a cost effective price, I would highly recommend buying this kit. Between this air kit and my cat-back system I spent about $825 and have a very big performance gain over stock.

      Easy Install, WAY Better Than Stock!!

      The good: Looks great, gets rid of the intake tube silencer, easy to install IF....(see below). The bad: If you have the Ford Performance Passenger side oil/air separator, the included air hose fitting is 180 degrees so it faces the oil/air separator and will kink the hose if you install it straight. You will have to get creative and route the hose in a "U" shape to clear. Other than that it's great!
