Banks Power Ram-Air Intake - LLY

The 6.6L Duramax turbo-diesel engine continued to gain popularity with the release of the 2004-2005 GM LLY, which was an improved version of the earlier LLY Duramax. The LLY boasted 310 horsepower and 605 lb/ft of torque, a significant increase in power. While the LLY certainly provides respectable performance, many LLY owners are looking to boost their engine's performance further. One cost-effective and straightforward way to achieve this is through bolt-on modifications, with a cold air intake being a particularly appealing option. A Chevy LLY Cold Air Intake is an excellent choice for those looking to increase power and torque without breaking the bank or spending an excessive amount of time on installation.

Not only will a Banks Power Ram Air LLY Duramax Cold Air Intake give your 6.6 a few more ponies and a significant amount more torque, but it will also increase internal airflow, improving turbo efficiency. In addition to those benefits, you can also expect marginally better gas mileage, better acceleration, and improved turbo responsiveness. Ultimately, a GM 6.6 LLY Duramax intake is a fantastic first mod if you are just getting started or a great finishing touch for a highly modified 6.6 that would benefit from higher airflow.

(2004-2005) GM 6.6 LLY Duramax Banks Power Cold Air Intake Benefits:

• Gain up to 15 hp & 25 lb-ft of torque
• Up to 57% 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 LLY Banks Power Intake comes with tons of awesome benefits and features. The Banks Power Ram Air LLY 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 LLY Duramax 6.6. The Banks Power LLY 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 LLY Filter Options

The Banks Power 6.6 LLY 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 LLY 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.
