New K&N Replacement Air Filter for 2017 6.6L Duramax LP5 Chevy and GMC 2500 & 3500

K&N replacement filters are designed to increase power without causing addtional engine wear

K&N has developed a replacement air filter for Silverados and Sierras powered by the new LP5 Duramax

Both the 2017 Chevrolet Silverado and GMC Sierra 2500 and 3500 are powered by the latest generation 6.6L Duramax Diesel LP5 engine. Introduced in the 2017 model year, it is the most powerful diesel engine GM has yet produced, with output of 445 horsepower @ 2,800 rpm and earth-moving torque of 910 lb-ft @ 1,600 rpm.

But despite this increase in power, there’s still room for improvement. Take the K&N 33-5065 replacement air filter. Not only has it been designed to improve airflow into the engine, but with its million-mile design, will keep numerous disposable air filters out of landfills for years to come.

The LP5 Duramax is a significant departure from its immediate predecessor. While still a 90-degree V8, the cast-iron engine block features induction-hardened cylinder walls. As far as the rotating assembly is concerned, a forged steel crankshaft rides on five cross-bolted main bearing caps, powdered metal alloy connecting rods with larger journals, and cast aluminum “remelted” pistons have all been made more robust. The high-pressure, common-rail direct-injection fueling system can feed even more fuel than in the past, while the electronically-controlled, variable-geometry turbocharger operates at a higher boost pressure.

The way to achieve increased horsepower and torque in a turbocharged diesel engine is to deliver more air to the intake. The electronics will feed fuel into the cylinder to match the detected temperature and volume of the intake flow. The greater volume of cooler air that can be fed into the cylinder will result in a greater volume of fuel being injected, delivering the sought-after increase in power.

Dirt and dust are no match for K&N's championship-winning air filters

Preventing engine damage while off-road racing prompted the development of the first K&N filter

K&N replacement air filters have been designed to increase airflow into the engine. The key is that K&N replacement air filters are manufactured from multiple layers of oiled extra-fine weave grade cotton filter media originally developed for off-road racing competitors to keep damaging dirt out of their engines while providing improved airflow.

In its filters, K&N incorporates three well-proven scientific principles to effectively trap harmful dirt and dust. One is interception, another is impaction, and the third is diffusion. The first traps large particles as they first enter the filter, the next two capture smaller particles by different means. The result is a high degree of filtration without the risk of clogging inherent in a paper filter.

Oiled cotton has been selected as it offers less resistance than traditional filters. Each design is verified through K&N’s in-house ISO 5011 compliant filtration testing lab, which ensures that your K&N filter provides high airflow without putting engine protection at risk.

And once you’ve installed your K&N 33-5065 replacement air filter you’ve eliminated the need to buy another air filter for the life of your covered 2017 Chevy or GMC LP5 Duramax Diesel. The only maintenance is a simple service you can do yourself.

The K&N Replacement Filter is engineered to fit perfectly in the original factory airbox

At intervals of around 50,000 miles, depending on your driving conditions, use a K&N 99-5000 air filter cleaning kit to clean and re-oil your air filter.

The process cleans the filter bringing it back to a like-new level of performance and ready for another 50,000 miles of driving. Your one K&N air filter is designed to last for the lifetime of your vehicle, which K&N guarantees will perform for up to 10 years or 1,000,000 miles without requiring replacement.
