Your truck’s air intake system is as important as its fuel system. A severe air intake issue will cause similar performance drops, starting problems, and fuel inefficiency as a fuel system problem. So you should make sure your vehicle is breathing properly with quality parts from Norcal Diesel Performance. While the system may seem simple at first, plenty of parts are involved between the air outside and the vehicle’s turbocharger. This includes the intake, boost tubes, resonators (and resonator plugs, and arguably most importantly -- an intercooler. Because intercoolers work by chilling air before it gets to your vehicle’s turbocharger, a good one can help boost performance in other circumstances, too. Working in a hot climate? An intercooler can make a difference. Working at altitude? Again, as the air entering the turbocharger will be denser after going through an intercooler, this single part can mitigate any performance losses your vehicle usually experiences when working higher up. If you shop with Norcal Diesel Performance, several air intake options are available for your Chevy/GMC truck. These parts come from reputable suppliers like Mishimoto, BD Diesel, and S&B Filters.
