Never content to rest on their laurels, our good amigos at K&N have come up with a brand-new, power-boosting air intake setup just for you. The new High-Flow air intake system for 2007-08 GM Duramax 6.6L diesels is said to provide close to 20 additional horsepower. The K&N system replaces the factory intake assembly with an all-new design. It’s said to increase airflow and dirt-catching capacity, it comes with a million-mile limited warranty, and it never needs replacing. You can install it in your own driveway in 90 minutes or less, and you can find out all about it at www.knfilters.com or by calling 800/868-3333. Happy filtration!
