I am looking into headers for my 96 F250 351w. The Edelbrock headers (6649) that I am looking at state for 88-96 F250 351w without A.I.R. I am not familiar with air injection. How can I tell if my truck has air injection or not? What should I see or not see under the hood? Any help is greatly appreciated.

Thanks,

Kevin

you should find an air pump mounted near the alternator it will have multiple rubber hoses with valves that have vacuum lines connected to them
