The AEM 21-767C Performance Cold Air Intake System produces horsepower and torque gains by replacing your vehicle’s restrictive factory air filter and air intake housing. This air intake system was designed, tuned and dyno-tested to fit specific Ford Explorer models. Air enters the system through an oversized AEM Dryflow synthetic washable air filter for outstanding air flow, filtration and performance. The air filter is placed into the original air box space and is protected by a heat shield which is designed to reduce intake air temperature and increase horsepower. The air intake tube is constructed from mandrel-bent aluminum featuring a durable gunmetal gray powder coated finish. This air intake system was developed to accommodate the engine’s factory emissions control devices including the mass air flow sensor and engine vent line. The tapered cylinder shaped AEM Dryflow air filter is made from an oil-free, synthetic filter media that can be used for up to 100,000 miles before cleaning is needed (depending on driving conditions). The air intake system is easy to install with commonly available tools and it is backed by AEM's Lifetime Limited Warranty. Some AEM air intakes are not legal for sale or use in California and other states adopting California emission standards, while others are 50 state legal.

I put this CAI on my 2016 Ford Explorer XLT. The installation was smooth as when installed a (Brand Replacement) CAI on my F-150. The only hang up I had was getting the heat shield to fit into the stock grommets, the heat shield slightly set upon the transmission fluid reservoir; but with some force it fit snug. It seems like the bottom left corner of the heat shield could have been cut at an angle for a slightly better fit. Nonetheless this CAI is AWESOME! First, the SOUND is tough, particularly at high rpms. Second, the LOOK of the heat shield and tube in the engine bay, looks like it is meant to be there unlike the (Brand Replacement) CAI. Third, the POWER gain is noticible; when you lay into the throttle it accelerates quicker, and pushes you back in your seat a little more. It's hard for me to trust the dynocharts for any CAI, there just are too many variables at play to know what will happen in your application. I do know that more air equals more power. And this CAI brings in the air. Therefore, I wouldn't dwell to long on (Brand Replacement) alleged 13 HP gain. I can't prove it's erroneous, but it seems a bit far fetched. Thus, if you are looking for a CAI that looks SLEEK, sounds FIERCE, and TRULY increases your Explorer's power then go AEM and buy this awesome CAI.
