Replacing the restrictive, stock airbox on your 07.5-10 LMM Duramax is probably the easiest upgrade you can do to increase power, throttle response, and fuel economy. Why is the stock airbox so restrictive you may ask? The physical size and media of the air filter limits the amount of airflow that can physically move through it and to the turbo.
Blackhawk Induction air intake systems feature an oil-free synthetic filter media, black powder-coated aluminum intake tube, and all-black components. The layered DRYFLOW synthetic filter provides increased airflow and exceptional engine protection without requiring oil, and a steel heat shield helps protect intake air from the high temperatures of your engine bay. The system can typically be installed in less than 90 minutes.
