The K&N 77-1533KP high-flow performance air intake system is a free-flowing, mandrel-bent aluminum tube air induction system designed to fit some Dodge Ram 1500, 2500 and 3500 Pickup models. The restrictive factory air filter and air intake housing on your vehicle are replaced by this K&N air intake system which is designed to dramatically reduce air flow restriction as it smoothes and straightens air flow. The improved air flow allows your engine to inhale a larger amount of air than it would from the stock air intake. More air means more usable power and acceleration throughout your engine’s RPM range. The 77-1533KP air intake comes with a chrome topped K&N high-flow air filter and a heat shield that installs into the previous air box space. Air is directed through the intake tube into the engine’s throttle body for a guaranteed power gain. The intake tube has an attractive chrome-like finish that's made to last and it accommodates the factory air temperature sensor and crank case vent hose. 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 90 minutes or less using existing factory mounting points. The tools needed are a screwdriver and ratchet set. Some K&N 77 series air intakes are not legal for sale or use in California and other states adopting California emission standards while others are CARB exempt and 50 state legal. Check the K&N catalog or website for vehicle applications and specific CARB status for each vehicle and air intake.
K&N High-Flow Cold Air Intakes are state-of-the-art. They begin with the largest conical air filter that can fit into the engine compartment while still using factory holes/mounts. This extra filter size provides even more airflow at lower restriction than a K&N OE Replacement Filter because the standard filter is limited to the size of the factory air box. The oversized air filter also captures and holds more dirt, extending the service life before cleaning is required. The filter is isolated from high engine temperature by a heat shield designed to lower the temperature of the air entering the engine, which increases horsepower. The filter is then attached to a high-density polyethylene tube. The molding process allows tubes to be precisely formed in order to reduce turbulence and accelerate airflow into the engine. This is why some tubes have unique shapes; they're engineered specifically for each application. Finally, the tube connects to the engine with adapters made from high-strength silicon & reinforced nylon to ensure long life.
