Chevrolet Duramax Diesel Intake

Marked by a dramatic hood scoop, the 2017 Chevrolet Duramax now features a patented air intake system that drives cool, dry air into the engine for sustained performance and cooler engine temperatures. This of course means better performance when towing heavy loads, working under less then desirable working conditions or quite simply, real world driving.

The all new air intake system provides 60 percent more air to the Duramax diesel engine from an inlet at the front of the hood, keeping the air to the engine very close to the outside ambient temperature and much cooler than the air under the hood.

Obviously cooler air means a better running engine, especially in conditions where the engine and transmission temperatures can quickly rise. There is also a ram air effect from the incoming air that at highway speeds can help pack more cool air into the engine, much like what you would see on the older classic muscle cars of yesterday.

“The 2017 Silverado HD was engineered to provide maximum utility for our customers in even the most extreme situations,” said Eric Stanczak, chief engineer, Silverado HD. “While developing this all-new induction system, we considered our customers towing a maximum-weight trailer through the Eisenhower Tunnel on a hot, rainy summer day.”

A brief example of how it works, the air charge enters an expansion chamber containing a sharp 180 degree turn on it’s way to the filter housing. That creates a velocity change that causes humidity to mist or form larger, heavier droplets that are flung centrifugally against the outside wall of the housing. The collected water drains through a valve, while the air charge continues on to the filter housing and into the engine.

Testing was spared no expense as Chevrolet wanted to make sure the effectiveness of the system was proven in real world driving conditions the truck would see everyday. from misty rains to monsoon type downpours; from powdery snow to wind driven ice pellets; from desert dust to arctic cold, the results delivered maximum engine performance and that is just how we like it.
