The K&N 57-3095 is a 57 Series FIPK cold air intake for the Chevrolet Colorado L4-2.8L DSL diesel, covering 2016-2019 model years. Its black roto-molded high-density polyethylene tube helps increase the volume of airflow to your engine, and the kit pairs it with a washable filter. The filter uses oiled cotton filter media and sits inside a custom heat shield meant to keep intake air away from engine bay heat.
The manufacturer positions the system as a full replacement for the factory filter and intake tube, and markets it as guaranteed to increase horsepower and torque. The reusable filter is a practical reason to buy it over a disposable replacement, since you clean it rather than repurchasing it. Owners on user forums are divided, though. Some argue that oiled filters on a turbocharged diesel can let oil migrate into the intake and foul the mass airflow sensor, while others report that the stock intake flows enough air that an aftermarket intake is pretty much null. Weigh the stated gains against those concerns before you buy.
Yes. The manufacturer's install sheet has you remove the mass air sensor from the factory housing and mount it in the K&N adapter, using the gasket the kit provides.
The manufacturer describes the filter as washable and reusable, so it is cleaned rather than replaced. Follow the manufacturer's cleaning guidance and oil recommendations.
User forums have raised this concern. Some owners worry that oil from an oiled filter can travel into the intake on a turbocharged diesel and affect the mass airflow sensor, so it is worth weighing before purchase.
The manufacturer states the system is typically installed in under an hour. Start by turning off the ignition and disconnecting the negative battery cable. Disconnecting the battery erases stored settings, so write down radio presets first, since some radios require an anti-theft code after reconnection. Transfer the mass air sensor to the K&N adapter with the provided gasket, fit the heat shield, and connect the intake tube to the throttle body with the supplied coupler. The manufacturer's instructions warn that skipping the provided hardware can cause installation problems, so use only the included fasteners and clamps. Check the EVAP and crankcase vent connections before you start, since the general K&N guide calls for disconnecting them from the intake and valve cover.
