ISO 5011 Filtration Testing.
A mountain of dust and our 1/2 million dollar lab is how far we've gone to make sure your engine is protected. 99.44% efficient @ 653 CFM (ISO Coarse Dust). 48.39% more airflow than the stock intake!
Fits better than stock.
An integrated tab makes for a seamless, single bolt attachment, to the frame of your Duramax just as done by the stock air box. Most installs take about 30 minutes.
Huge secondary intlet.
Airflow with options.
When its cool out, feed your engine more air through the air box's secondary opening. Just in case the thought of all that extra cold air makes you shiver, a plug is provided to seal off the extra inlet.
Avoid check engine lights.
We designed this kit to avoid check engine lights with a properly mapped Mass Air Sensor. This is where we run away from the competition. Vehicles are becoming more complex. S&B devotes a huge amount of resources to engineer intakes that will allow your engine to run properly with the stock calibration or with enhanced tuning.
Quality Down to the Last Screw.
