2017-2019 Duramax Intercooler Guard Bumper Insert (L5P-EXT-A191)

Fits:

The front end of your L5P does a lot more than just look good. Behind that bumper sits your intercooler, and it does not take much for rocks, road debris, ice, bugs, or highway junk to start beating it up. This Dirty Diesel Intercooler Guard Bumper Insert gives your 2017-2019 Duramax a clean, finished look while adding a layer of protection where your truck actually needs it.

Designed to fit the factory bumper opening on 2017-2019 Silverado and Sierra 2500/3500 Duramax trucks, this insert helps shield the intercooler area without killing the airflow your truck relies on. Whether your L5P is a daily driver, tow rig, work truck, or something that spends more time getting dirty than sitting pretty, this is a simple upgrade that makes sense.
