The K&N 33-5065 is a reusable panel-style replacement for the factory paper filter in the 6.6L V8 turbo-diesel Silverado 2500HD. Its multiple layers of premium cotton gauze treated with a specially-designed tacking agent form the filter media, and K&N's oiled, layered cotton design is meant to balance higher airflow against contaminant capture. Choose it over stock if you want a filter you can clean and reuse instead of replacing a disposable one at every service. The manufacturer backs it with a No-Hassle Lifetime Limited Warranty, and it only needs cleaning every 75,000 miles under normal highway driving conditions, per the manufacturer's listing.
For a 2017 2500HD owner searching for a 6.6L diesel drop-in air filter, this K&N is fitted to the factory air box, so no cutting or bracketry is needed. The manufacturer lists it for the 2017-2019 CHEVY SILVERADO 2500 HD V8-6.6L DSL, although one K&N regional site lists only 2017-2018, so confirm your VIN before ordering. Cleaning and re-oiling are the main maintenance tasks: the manufacturer specifies 4.5 oz (133 ml) of filter oil for re-oiling, and the filter's exterior measures roughly 11 by 11 inches. Owners searching for a washable diesel air filter, a reusable 6.6L Duramax replacement, or a lifetime-warranty K&N drop-in will find this model's specs and install approach straightforward.
The manufacturer lists fitment for 2017-2019 Chevrolet Silverado 2500HD trucks with the 6.6L V8 diesel. A K&N regional site lists only 2017-2018, so the manufacturer should be contacted to confirm coverage for a 2019 truck.
The manufacturer states the filter needs cleaning about every 75,000 miles under normal highway driving. Owner-reported intervals on user forums vary, and details differ across sources, so confirm the schedule with the manufacturer if you drive in dusty or severe conditions.
The manufacturer offers a No-Hassle Lifetime Limited Warranty on this filter. Limitations apply, so review the manufacturer's warranty terms before relying on coverage.
This is a drop-in swap. The manufacturer designs the filter to fit directly into the factory air box, so you remove the stock filter and seat the K&N in its place. The manufacturer's installation instruction sheet for this part is the authoritative reference for steps, tools, and any seal or orientation notes, and I could not retrieve its full contents during research, so review it before starting. Clean the air box interior of loose dust before installing the new filter so no debris enters the intake. Re-oil the filter as directed by the manufacturer's care guidance when you clean it.
