Frequently Asked Questions
Q: Does this intake require a custom tune? A: No. This is a true bolt-on upgrade for the 7.3L Powerstroke. No ECU tuning is required to realize performance gains.
Q: Will this fit my early 1998 F-350? A: Only if your 1998 truck was manufactured after December 7, 1998. Early 1998 models use a different MAF sensor bracket and are not compatible.
Q: How do I clean the dry filter? A: Use low-pressure compressed air or mild soap and water. Allow to fully dry, then reinstall. No re-oiling is needed or recommended.
Q: Does it include all installation hardware? A: Yes — all clamps, brackets, heat shield, and hardware are included. No extra parts are required.
Q: Will this improve my towing performance? A: Yes. The increased airflow and reduced restriction help maintain power under load, improving throttle response when towing heavy trailers.
