I honestly feel that spark plugs are a personal preference decision, I personally have never bought plugs for any of my vehicles that didn't t work, generally speaking the pricier plugs usually last longer than the cheaper ones I feel.Alright so here's the update... DEFINITELY had a vacuum leak... Found a FEW cracked hoses, bad couplings and replaced the pcv valve and gromet while I was at it. They were really loose and cheap so I figured why not. After all that my check engine light came back on, shaking persisted so I got it on a reader and found that cyl 8 was misfiring. Changed out the spark plug and all better now. I'm going to do the rest; coil packs look ok and I'm short on money so I'll leave those alone. One more question if anyone wants to weigh in: I bought motorcraft plugs, as that's what I was told was used in my vehicle and in fords commonly; but a "car-guy" friend suggested Bosch Platinum +2 plugs. I've found both for around the same cost... Any suggestions/pros/cons either way?? Thanks for all the help so far, you guys have gotten me a long ways
I work for a parts store an me their best brand is ngk iridium, I got 8 plugs for free so I decided to use them, they retail for 9$ each and they have been in for over a year and my truck runs beautifully, we have -40-45°c winters with the windchill and +30+35°c summers with the humidex, and I just finished driving 5000kms across the country plugs are still perfect, trucks runs so nice I can't even hear it running it's so smooth and quiet.
If OEM are available then buy them but if you're on a budget you should be OK with a cheaper plug, I'm sure it will be better than keeping your old plugs. I realize everyone is pro motorcraft for obvious reasons I just felt I'd give my perspective on it also. Best of luck
