K&N Air Intake Adds Estimated 15 Horsepower to 2017 6.2L Duramax
- 12 Feb 2018
But despite this increase in power, there’s still room for improvement. Take the K&N 77-3101KP high-flow performance air intake system. It’s been designed to improve airflow into the engine, which will add an additional estimated 15.22 horsepower and 32.99 lb-ft of torque at the drive wheels. The LP5 Duramax is a significant upgrade from the previous version. Still a 90-degree V8, the cast-iron engine block features induction-hardened cylinder walls for durability. A forged steel crankshaft rides in five cross-bolted main bearing caps, with powdered metal alloy connecting rods with larger journals. The high-pressure, common-rail direct-injection system has an increased capacity, while the electronically-controlled, variable-geometry turbocharger operates at a higher boost pressure. One drawback of turbocharged engines is that the process of compressing the intake air heats it up considerably, as a function of how much the turbocharger pressurizes the incoming air. Internal combustion engines work best with cool intake air, so an intercooler is typically installed between the turbocharger and the intake ports. A K&N Performance Intake System features a heat shield that helps protect the cool incoming air from being affected by high underhood temperatures. This assists your engine’s intercooler, as it delivers cooler air to the turbocharger, the output of which is lower in temperature, supplementing the drop in intake temperature the intercooler is designed to deliver.
The free-flowing K&N air intake tube significantly reduces restriction to incoming airflow over the stock tract, as well as calms power-robbing turbulence. Air passes through an aerodynamically-verified polished aluminum intake tube directly into the engine’s throttle body. The intake tube accommodates the factory mass air sensor, fuel pressure hose, and crankcase vent hose. Once you’ve installed your K&N cold air intake system, you’ve eliminated the need to buy another air filter for the life of your 2017 Chevy or GMC LP5 Duramax Diesel. The only maintenance is a simple service you can do yourself. At intervals of up to 100,000 miles, depending on your driving conditions, use a K&N 99-5050 Air Filter Cleaning Kit to clean and re-oil your air filter. Not accounting for the time for the filter to dry completely before installation, the entire process should take less than 30 minutes.
You can order the filter simply by clicking on the part number 33-3064 as well as order the Air Filter Cleaning Kit 99-5050.
