2017-2019 L5P Duramax Intake

Built to order — not a shelf part Current build & coat time: 7–14 business days Every Felder Kustom Fabrication part is fabricated after your order is placed, so lead times run longer than off-the-shelf parts. Lead time varies with our current build queue — contact us before ordering if you need an exact date. The FKF 2017-2019 L5P Duramax 4" Intake is a complete cold air intake kit built around mandrel-bent aluminum tubing and a CNC router-cut aluminum airbox. It runs one of the largest filters offered in an L5P intake — an 11" dry filter — and everything needed for the install is in the box.

We also use a 5"-to-4" adapter boot where the intake meets the airbox. That creates rigidity and acts as a cushion, which keeps your powder coating from wearing at the airbox seam.
