Wehrli 4" Intake Kit – 100333

Fits 2003–2007 Ford F-250 / F-350 with 6.0L Powerstroke

Unleash airflow and performance from your 6.0L Powerstroke with the Wehrli 100333 4" Intake Kit. Designed to maximize intake efficiency, this kit replaces the restrictive factory intake system with a high-flow 4" mandrel-bent aluminum tube and a large reusable filter. Whether you're towing, daily driving, or running a tuned truck, this intake improves turbo spool, throttle response, and engine efficiency—all while delivering a clean, upgraded look under the hood.
