Special Notes: Do NOT over oil your air filter after cleaning it.

When restoring your air filter with K&N Power Kleen the best way to do this is to allow your air filter to fully dry before using the K&N Air Filter Oil. However, don't be overzealous when using the K&N air filter oil. Over oiling your air filter may cause MAP sensor dysfunction. Purchasing a second air filter is a great way to know you have one ready for use at all times.

Performance Chevy and GMC Duramax K&N Air Intake Kits

K&N is a pioneer manufacture in the diesel aftermarket performance cold air intake system arena. Their filters were created for dirty dusty on and off-road environment where engines are always requiring maximum horsepower and enhanced acceleration meanwhile keeping the turbocharger protected and spooling rightfully at all times. K&N cold air intake systems offered for diesel applications help provide an increase of horsepower. They verify their horsepower output numbers with their 5 in-house dynamometers. No intake is sold unless it is increasing horsepower and efficiency. K&N prides their product on diesel air intakes systems that put out verifiable increases in performance.

The K&N 77 Series Performance Air Intake Kit replaces the restrictive factory air filter and air intake housing on the Chevy and GMC Duramax Diesel truck. The air intake kits are designed to dramatically reduce intake restriction as they increase smooth and straighten air flow. This allows the Powerstroke 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 Chevy and GMC Duramax air intake comes with a K&N high-flow air filter and a heat shield 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 air filter restriction gauge. The oversized conical air filter can be used for up to thousands of 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 only tools needed are a screwdriver and several wrenches. Similar to the 57 Series FIPK filters, the K&N 77 Series Performance Air Intake Kit filters come with K&N's Million Mile Limited Warranty however some are NOT street legal in all 50 US States.

K&N 77 Series Performance Air Intake Kit Eliminate Air Restriction

The K&N 77 Series Performance Air Intake Kits are built for many different vehicles and represent a dramatic improvement over a K&N original equipment (OE) replacement filter alone; they use only non-metallic rotationally molded tubes that can reduce air temperature and decrease intake sound over a metal tube. Restriction can exist between an air filter and the engine reducing the benefit of a K&N Air Filter. The weakest link in the airflow process robs a vehicle of its natural horsepower. Often that weak point is the factory air path leading to the Engine. K&N air intake systems virtually eliminate air path restriction by replacing the air filter and the entire air path to the engine. The aerodynamically engineered tube drives a massive amount of air into an engine, which translates into power.

The Chevy and GMC Duramax performance air intake kits are truly state-of-the-art. Starting with the largest conical shaped high-flow air filter that will fit into the engine compartment while using factory holes and mounting points, this extra filter size provides even more airflow at lower restriction than a standard K&N OE replacement filter that is limited to the size of the factory air box. The oversized air filter also captures and holds more dirt increasing the service life before a cleaning is required. When possible, 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. Attached to the filter is a rotationally molded tube made from interlaced High Density Polyethylene which allows the precise shape of the tube to reduce turbulence and accelerate airflow into the engine giving birth to why some tubes have unique shapes that are specifically engineered for each application. Finally the tube is connected to the engine with adapters made from high strength materials such as silicon and reinforced nylon and ensures long life. Put all this together and you have the best high-flow intake system available today.
