The K&N E-1986 is a round, reusable High-Flow replacement element made from layered, oiled cotton gauze. It is sized to sit in the factory airbox of the 4.8L and 6.0L V8 Chevrolet Express van, and the manufacturer rates its filtration at up to 99% efficiency. It arrives pre-oiled, so it can go straight into the airbox.
The case for paying more than a disposable paper element rests on lifespan. The manufacturer designs this filter to stay in service for the life of the vehicle, with a cleaning interval of about every 75,000 miles under normal highway driving, and it carries the No-Hassle Lifetime Limited Warranty. The manufacturer also compares the cost of repeatedly buying disposable filters against one washable element over 200,000 miles of highway driving. For a buyer who keeps a work van on the road for years, that trade-off is the real value, along with the airflow benefit the manufacturer attributes to its oiled cotton design.
The manufacturer lists this element for 2008-2017 Express Van 4.8L/6.0L models. Fitment charts elsewhere show wider Express 2500/3500 and GMC Savana coverage, so confirm your exact model year and engine with the manufacturer before ordering. Searchers looking for a K&N E-1986 4.8L 6.0L Express van air filter, a washable high-flow drop-in for a 2008-2017 Chevy Express, or a V8 Express cold-air-style filter swap will find this part relevant. The installation is a drop-in airbox swap that follows the manufacturer's installation instruction sheet.
The manufacturer lists it for Chevrolet Express Van 4.8L/6.0L models from 2008 to 2017. Other fitment charts show different year and model coverage, and those details vary, so confirm your VIN and engine with the manufacturer before buying.
According to the manufacturer, the element needs cleaning about every 75,000 miles under normal highway driving.
The manufacturer states the filter is pre-oiled and ready to drop into the factory airbox. The manufacturer also specifies a re-oiling amount of 2.95 oz (87 ml) for future servicing.
The manufacturer designs this element to install easily into the factory airbox, so the job is a filter swap rather than a modification. The manufacturer publishes an installation instruction sheet for this part, and that sheet should be followed for the exact procedure. Before closing the airbox, confirm the element sits fully seated and the lid seals evenly. Tools, torque values, and any airbox-specific steps were not confirmed in this research, so check the instruction sheet before starting.
