Can anyone please tell me the correct gapping for the spark plugs for a 91 Ford F250 5.8 ltr.

I believe it is .042"-.046" , but check the emissions sticker under the hood to be sure.

Also, a lot of the folks who know about this don't frequent the "New Member Introductions" forum. If you post in the "Small Block V8 (221, 260, 289, 5.0/302, 5.8/351W)" or "1987 - 1996 F150 & Larger F-Series Trucks" forums you'll find folks who know for sure.

Welcome aboard!
