04.5-05 GM 6.6L LLY Duramax Banks Ram-Air Intake System With Dry Filter

Fits: 2004.5-2005 GM 6.6L LLY Duramax

This Banks Power 42135-D Ram Air Intake System with Dry Filter for your 2004.5-2005 GM 6.6L LLY Duramax comes with astonishing best gains in airflow, air density and power. Its large dry synthetic air filter requires fewer cleanings than competitive filters (stock's small paper filter is not reusable). With its giant 7-1/8 outlet, streamlined components and enclosed cold-air box that keeps hot engine air out of the intake, the Ram-Air flows up to 57% better than stock and up to 23% better than others for greater power (up to +39hp and +69 lb-ft more than a tuner alone), improved mileage and less black smoke. (An indicator of unburned fuel, black smoke is power you can see but not use!!)  And these unique 4-1/2" bellows accommodate engine movement, which prevents component damage and prolongs service life. Designed to not cause fault or error codes.
