    Increased Performance. The K&N Series 77 High-Flow Performance Cold Air Intake system is compatible with your 2003 to 2008 Dodge RAM, equipped with a 5.7L engine. You'll enjoy increased horsepower. This is a replacement for the restrictive factory air filter and intake housing. This system has been designed to enhance throttle response and engine sound. Another benefit is better fuel economy due to the increased airflow into the engine.

    No Tuning Required. This exclusively designed cold air intake system does not require tuning. Your RAM will have higher-caliber performance without the need to reprogram your truck's computer. The high-quality factory tuning will provide heightened power in your truck.

    Series 77 Air Filter. This oversized, cone-shaped filter will last up 100,000 miles before it will need to be serviced, depending on driving conditions. You can simply wash and reuse this filter though the lifetime of your RAM. The heat shield and chrome-topped, high-flow filter are installed in the prior air box space.

    Distinctive Design. This mandrel-bent aluminum tube air induction system was designed to replace the air intake housing and restrictive factory air filter. It dramatically decreases the intake restriction to efficiently straighten and smooth air flow. Due to this advanced engineering, your truck's engine can intake a larger amount of air compared to the factory air filter assembly. Your truck will experience improved acceleration and power in the engine's RPM range because of this heightened air flow. The free flowing aluminum tubing has a distinctive chrome-like finish that adds to the durability factor. As air is pushed into the engine's throttle body, your truck will have power gains. The intake tube works well with the air temperature sensor and crank case vent hose.

    Basic Installation. Installation is easy and can be finished in under 90 minutes. The system is mounted on existing factory mounting points. Common tools like a ratchet set and screwdriver are used. The kit includes all required parts and installation directions.

    Limited Warranty. K&N offers a Million Mile Limited Warranty. The cold air intake system performs well up to 100,000 miles before service is needed, depending on driving conditions.

    CARB Certified. The CARB EO Number for the K&N Series 77 Cold Air Intake system is D-269-37. It is street legal in all US states.

    Application. The K&N Series 77 High-Flow Performance Cold Air Intake system was designed to fit the 2003-2008 Dodge RAM equipped with 5.7L engine.

    Technical Note. The K&N Cold Air Intake is not designed for vehicles equipped with a Body Lift.
