Air Intake 99-03 Ford F250 7.3L Oiled

The Air Intake 99-03 Ford F250 7.3L Oiled is a closed-box cold air induction system engineered for 1999–2003 Ford F-250 and full-size SUV platforms equipped with the legendary 7.3L PowerStroke diesel engine. Designed for mechanics and truck owners seeking measurable intake efficiency gains, this system replaces restrictive factory intake pathways with a larger diameter tube and strategically positioned filter housing to draw cooler ambient air directly into the combustion chamber. Whether you're running stock power or building a modified diesel, a quality cold air intake addresses one of the most fundamental bottlenecks in naturally aspirated engine breathing.

This kit features a durable plastic construction finished in matte black, paired with a reusable oiled cotton filter element that captures particulate while maintaining low restriction across the RPM band. The oiled media design—commonly found in high-flow applications—traps dust and contaminants while preserving airflow superior to paper filters, making it ideal for daily driving and light off-road use. The closed-box design isolates the filter from engine bay heat, maintaining cooler intake temperatures and optimizing volumetric efficiency. Installation is straightforward for anyone with basic mechanical knowledge, utilizing existing engine bay mounting points and factory ducting passages where possible.

This intake system is ideal for F-250 owners who want responsive throttle feel and modest power gains without complicated tuning or expensive modifications. The reusable filter element reduces long-term maintenance costs compared to disposable paper alternatives, requiring periodic cleaning rather than replacement. Compatible exclusively with 1999–2003 Ford F-250 and full-size SUV models powered by the 7.3L PowerStroke engine, this kit integrates cleanly with stock manifold geometry and sensors. Weighing approximately 15 pounds, installation requires no permanent modifications to your truck's factory systems.
