2026 Toyota 4Runner Performance Air Intake Kits

“Momentum’s unique filter-to-housing interface was built to feature the largest air filter possible. This 8″” tall 360-degree radial flow air filter features a 4″” flange and our oil-free Pro DRY S media with three layers of synthetic media for maximum convenience. Its progressive layering provides great filtration efficiency and dust holding capacity, while not requiring the use of oils. This media is best suited for street use. Its inverted top makes for more filter surface area, resulting in longer service intervals, while reinforced metal provides maximum strength to prevent filter collapse. The smooth one-piece sealed housing, constructed of heat-resistant cross-linked polyethylene (XLPE), features our patent-pending filter-to-housing interface. Its innovative design minimizes the total number of parts, making for an easy installation. A clear sight window allows for hassle-free filter inspection, without having to disassemble your system. The housing connects to the factory air inlet duct but also captures air from the opening in the fender to provide more immediate cool air to the engine. This system features high quality, computer-designed, dyno-tuned intake tubes to achieve maximum power gains while maintaining a perfect fit. Their XLPE material is heat soak resistant and extremely durable. To maximize the amount of air going to this air intake system, aFe POWER D.A.S. 50-70119S is available and sold separately. The Dynamic Air Scoop will replace the factory air inlet duct and provide more cold air to the air intake system directly from the front of the vehicle. Stainless-steel clamps and silicone coupler are included for strength and durability. Momentum GT intakes are designed with fewer parts for a fast and easy installation.”

Spectre air intake systems are designed to get more horsepower and torque from your vehicle while working to protect your engine from harmful debris. This air intake comes with a red Spectre reusable low restriction air filter, high quality polished aluminum tubing and a black powder coated heat shield (where applicable) to help prevent engine air from entering the intake inlet. Spectre air intakes come with the necessary boots, clamps and hardware for an OE fit and finish.

The K&N DRYFLOW Air Intake System replaces your vehicle’s restrictive factory air filter and air intake housing. K&N intakes are designed to dramatically reduce intake restriction as they smooth and straighten air flow. This allows your vehicle’s engine to inhale a larger amount of air than the factory air filter assembly. More air means more usable power and acceleration throughout the engine’s RPM range. The DRYFLOW Air Intake System features an oil-free synthetic filter media providing increased airflow and exceptional engine protection without requiring oil. This allows cooler, denser air to be directed through a custom intake tube into the engine’s throttle body for a guaranteed power gain. The system can typically be installed in less than 60 minutes.

The K&N 57-9006 FIPK air intake system replaces your vehicle’s restrictive factory air filter and air intake housing. K&N intakes are designed to dramatically reduce intake restriction as they smooth and straighten air flow. This allows your engine to inhale a larger amount of air than the factory air filter assembly. More air means more usable power and acceleration throughout the engine’s RPM range. The 57-9006 air intake comes with a chrome topped K&N high-flow air filter that installs into the previous air box space. Air is directed through an aerodynamically engineered intake tube into the engine’s throttle body for a guaranteed power gain. The tube accommodates the factory mass air sensor and an engine vent line. The oversized air filter can be used for up to 100,000 miles before servicing is needed depending on driving conditions. This air intake is relatively easy to install usually in 60 minutes or less using the existing factory mounting points. The tools needed are a screwdriver, socket set and several wrenches.

The K&N 57-9008 FIPK air intake system replaces the restrictive factory air filter and air intake housing in some Toyota 4 Runner and Pickup models. K&N intakes are designed to dramatically reduce intake restriction as they smooth and straighten air flow. This allows your engine to inhale a larger amount of air than the factory air filter assembly. More air means more usable power and acceleration throughout the engine’s RPM range. The 57-9008 air intake comes with a chrome topped K&N high-flow air filter that installs onto the factory mass air sensor and directs air into the engine’s throttle body for a guaranteed power gain. The oversized cone shaped air filter can be used for up to 100,000 miles before servicing is needed depending on driving conditions. This air intake is relatively easy to install usually in 60 minutes or less using existing factory mounting points requiring commonly available tools to do the job. K&N 57 Series FIPK’s are street legal in all 50 US states and come with K&N’s No-Hassle Lifetime Limited Warranty.

A high-density polyethylene (HDPE) rotationally-molded tube helps increase the volume of airflow to your engine, and provides a guaranteed increase in horsepower and torque. These systems are paired with a washable, reusable High-Flow Air Filter featuring oiled cotton filter media. The oversized, conical design allows you to go up to 100,000 miles between filter services under normal highway driving conditions. A custom heat shield helps protect intake air from the high temperature of your engine bay, and the entire system can typically be installed in less than 60 minutes.

“Momentum’s unique filter-to-housing interface was built to feature the largest air filter possible.
