Your engine works by combining air and fuel and then igniting that mixture. Just as fuel has to take a particular route from the fuel tank into the engine, the air your vehicle needs is fed in a certain way, too. It all starts at the cold air Intake.
Norcal Diesel Performance offers parts like the S&B Filters Cold Air Intake Kit (Dry Disposable Filter) 75-5105D can house other parts like the air filter. They’re usually found outside of the main engine bay, as engine bays tend to be hot. Proper placement allows an air intake to draw colder, denser air into the vehicle’s engine.
Air intakes tend to last a very long time, and are only usually replaced in certain circumstances. If your air intake is damaged, you should replace it. Air leaking directly from the intake isn’t making it to the engine any time soon. Similarly, a cold air intake upgrade is a good way to boost vehicle performance on a budget.
