The model featured comes with a dry extendable filter, which performs better in dusty conditions. That’s because you can clean it using pressurized air — something not possible with cotton filters.
CARB exempt
The kit comes with a large intake and a transparent lid to inspect the filter’s condition. The large airbox houses the filter. There’s also the option of going for the cotton cleanable filter, which improves the airflow even further (link to that is mentioned below). The kit is compatible with the 2015 – 2017 Ford F-150 and F-150 Raptor trucks with the 3.5 EcoBoost. It’s also CARB-exempt, so if you’re looking at using it in California, you won’t run into legal troubles.
What do we think of it?
In addition to what we’ve discussed earlier, the filter is made in a way to avoid check engine lights. The installation is said to be easy, taking up to 60 minutes for a complete installation. Check with the seller about the warranty because the Amazon listing lacks that information. As for the product itself, users have mentioned that the turbo spools quicker and the truck feels more responsive.

- Not much difference from stock in terms of sound

Like most K&N filters, it’s backed by a 10-year/million-mile warranty. The filter requires cleaning after up to 100,000 miles of highway use, which is also a big positive. And it can be installed in about 1.5 hours.
CARB exempt on most
As mentioned above, the compatibility includes the 3.5 EcoBoost engined Ford Flex, Explorer, and Taurus SHO. These vehicles need to be made with the model years 2011 – 2018 (Taurus SHO), 2013 – 2019 (Ford Explorer), and Ford Flex (2014 – 2019). The kit is said to add about 12.12 hp, but there’s a small caveat, its CARB status is not valid for use on all vehicles. The 2017 – 2019 Ford Explorer isn’t CARB exempt, according to the K&N data. But we’d suggest you check about that and the compatibility by dropping the seller a message.
What do we think of it?
The K&N Cold Air intake kit does a lot of things well. It adds power, sounds better, and since it’s CARB exempt (for most cases), it can be legally used in all US states as well. The installation is easy and it looks good when installed as well.

Cotton filter
Compatible with the 2015 – 2019 Ford F-150 trucks equipped with 3.5 EcoBoost, the filter kit includes the necessary hardware for a factory-like fitment. The filter itself is washable and reusable (cotton). The 2-piece heat shield keeps the heat out whereas the stainless steel clamps hold the filter in place.
What do we think of it?
There is a substantial cost advantage with the filter, but before going forward, you should check with the seller about compatibility and warranty (no info available on the latter). Users have appreciated that the filter works well. Spectre mentions to disconnect and reconnect the battery after installing the filter so that the ECU can recalibrate and doesn’t throw error codes at you. Some users have pointed out that quality can improve.
Pros

Another all-rounder (Oiled): aFe Power Magnum Force Cold Air Intake
- Outflows the factory intake by up to 70%
- 5-Layer progressively finer oiled, washable cotton gauze media allows maximum airflow for maximum power
- Powder-Coated one piece heat shield utilizes stock mounting locations
- Plastic cad designed, dyno-tuned, roto-molded intake tube
- This product is 50-state legal (CARB E.O Number D-550-28)
aFe produces quality intakes, and the Magnum Force Cold Air intake is no exception. It’s made for 2012 – 2014 Ford F-150 3.5 EcoBoost, comes with an oiled washable filter (cotton) and requires no drilling/cutting on factory components for installation. The filter is accompanied by a high-quality plastic intake tube, a top-mounted heat shield, and the necessary hardware.
Improved performance
The CARB-exempt intake improves the airflow and therefore the overall performance of the EcoBoost engine. Note that while aFe maintains that the filter is CARB-exempt, the Amazon listing says otherwise, so it’s a good idea to check with them to be sure. Another thing that you should confirm with the seller is the product warranty. aFe says air intakes have a warranty of two years, but since the listing has no information, you should confirm with the seller.
What do we think of it?
Users have appreciated the cold air intake’s overall quality and fit. The installation is easy, and there’s some perceivable gain in power as well. As mentioned above, check with the seller about CARB status for your truck and the warranty.
Pros
- Easy to install
- CARB exempt
Cons
- Limited info
