Banks Power Ram-Air Intake - LMM

In 2007, General Motors unveiled the GM Duramax LMM turbo-diesel V8, a new version of its predecessor, the LBZ Duramax. While not the most powerful Duramax engine with only 365 horsepower and 660 lb-ft of torque, the LMM's performance can be enhanced with select upgrades. One such upgrade is a quality cold air intake, which is affordable, easy to install, and highly beneficial.

By installing a Banks Power Cold Air Intake on your LMM 6.6, you can expect a noticeable increase in horsepower and torque, as well as a boost in internal airflow, which enhances turbo efficiency. Additionally, you can anticipate improvements in gas mileage, acceleration, and turbo responsiveness. Whether you're just starting out with modifications or have a highly modified 6.6 LMM in need of increased airflow, a Banks Power GM 6.6 Duramax intake is an excellent choice.

Since its founding in 1958, Banks Power has been a leader in the industry, renowned for its cutting-edge technology and innovative solutions that improve engine efficiency, increase power, and reduce emissions. Banks Power intakes are crafted with a blend of advanced product design, premium build materials, and meticulous airflow testing, making them the ideal option for achieving exceptional performance without breaking the bank. 

In addition to the impressive performance benefits that Banks Power's 6.6 LMM Duramax Intake offers, they are also known for their fantastic customer support with all Banks Power intakes coming with a lifetime warranty. Continue scrolling down for more details on the many benefits, features, and adjustable options available with the GM LMM Banks Power Cold Air Intake.

(2007-2010) GM 6.6 LMM Duramax Banks Power Cold Air Intake Benefits:

• Gain up to 15 hp & 25 lb-ft of torque
• Up to 47% increase in airflow over stock intake
• Quicker throttle response
• Flexible bellows elbow to accommodate engine movement 
• Improved turbo responsiveness
• Colder intake air temperatures
• 1-2 MPG Improvement
• Washable oiled filter/Disposable dry filter
• High-quality polyurethane and silicone construction

As shown above, the 6.6 LMM Banks Power Intake comes with tons of awesome benefits and features. The Banks Power Ram Air LMM intake is designed to draw in cool air from the bottom part of the passenger fender. This is a significant improvement over the factory airbox design, which pulls in warm air from the engine bay. The revised intake design not only lowers intake air temperatures but also gives the incoming air a more direct path to the turbo inlet. In combination, the higher amount of denser, cooler air results in significant power gains for your LMM Duramax 6.6. The Banks Power LMM intake also utilizes an integrated box seal that keeps out engine bay heat. Its high-quality polyurethane and silicone construction enables the intake to withstand temperatures of over 400 degrees without cracking or breaking. 

Banks Power Ram Air 6.6 Duramax LMM Filter Options

The Banks Power 6.6 LMM Intake can be ordered with two filter options: oiled cleanable cotton or dry. In terms of any performance differences, both filters will perform very similarly. Due to the fact that oiled filters have slightly larger pores, they typically keep out around 98% of incoming debris compared to 99% filtration for dry filters. The larger pores of an oiled filter are said to improve GM LMM airflow by a bit more over the dry filter option. Ultimately, you won't be able to tell while driving.

The main difference between oiled and dry filters is upkeep. Oiled filters are reusable while dry filters are disposable. Oiled filters can be cleaned with air filter cleaner and then rinsed off with cold water. Oil then needs to be reapplied to the filter after cleaning.
