3 1/2" Turbo Intake Horn for the 2017-2019 L5P Duramax with factory style Turbo. The OEM plastic intake horn is 2.4" diameter and we experienced a 25HP Gain with our 3.5" Horn when used with a Max Effort Tune. Tuning not required, this horn will work plug and play tuners or OEM calibration.

-NO Tuning required, bolt on!
-Will fit with OEM or any aftermarket intake kit.
-DOES NOT have provision for the OEM PCV Line. A PCV Reroute kit must but purchased or sourced separately. If you do not already have your PCV Rerouted it is recommended to purchase WCF100470 which is horn and pcv reroute combined.
-Will fit on stock truck no other modifications or upgrades necessary!

Purchased from: Wehrli Custom Fabrication

Wehrli has a diagram of their intake horn diameter compared to the stock one on the L5P posted, but until you take the stock piece off, you really can't appreciate how much it chokes down. Access during install is a little difficult, but Wehrli's fit and finish is perfect.
