2021+F-150/Raptor 3.5L aFe Rapid Induction Intake w/ Pro DRY S Filter

Large Three Layer Performance Air Filter:
This intake system features dual 8” tall conical air filters with three layers of oil-free synthetic media and requires no oil during maintenance to provide maximum convenience. Its progressive layering provides great filtration efficiency and dust holding capacity. This media is best suited for street and light off-road use. Pro DRY S filters are easily recharged with aFe's POWER CLEANER.

Mandrel-Bent Tubing:
Dual one-piece 3-1/2" mandrel-bent wrinkle-black powder-coated aluminum intake tubes direct unrestricted airflow from the massive filters to the turbos for more horsepower and torque.

Top Mounted Heat Shield Design:
aFe developed this lightweight aluminum wrinkle-black powder-coated heat shield to snap onto the top of the lower half of the factory airbox to provide a hassle-free installation utilizing factory mounting locations.

Aluminum Cover:
A wrinkle-black powder-coated aluminum cover is used to finish off this intake and add a sense of style to your engine bay.

Premium Hardware:
Premium hardware and clamps are used to securely mount the high flow air filters and the intake tubes.

Increased Airflow and Lower Intake Air Temperature:

Cold Air Intakes draw a larger volume of cool air from outside the engine bay compared to stock intakes. They are especially beneficial for turbocharged engines for two primary reasons: increased volume of air at intake and decreased intake air temperature.

Increased Air Flow:

The turbocharger's ability to "boost" is dependent on airflow from the intake. With increased air flow, the turbocharger can compress more air into the engine (as long as the air is cool). This results in higher boost pressure, enhancing power output and overall engine performance. A steady and ample supply of air to the turbocharger also allows it to spool up faster and deliver boost more quickly.

Decreased Intake Air Temperature:

Turbochargers have to work harder to compress hot air than cold air, impacting turbocharger efficiency. When intake air temperatures are lower, the turbocharger can compress more air into the engine, resulting in higher boost pressure and increased power output.

High intake air temperatures can also increase the risk of detonation (knocking), which can damage the engine. To prevent damage, the engine management system may reduce boost pressure or adjust the ignition timing, leading to a decrease in performance.

While some benefits of an upgraded intake can be observed on a stock tune, maximizing these benefits is achieved through custom tuning.
