17-19 Ford 6.7L Powerstroke K&N Air Filter Foam Insert

Fits: 2017-2019 Ford 6.7L Powerstroke 

The K&N 85-2003 Air Filter Foam Insert replaces the OEM foam block found in the factory airbox of your 2017-2019 Ford 6.7L Powerstroke. The OEM foam block presses against the air box window but is glued to the factory air filter, making it unusable when replacing the factory filter with a high flow drop-in K&N Filter. The 85-2003 comes pre-cut and ready to install for a perfect factory fit and finish.
