I was wondering if anyone has tried out the Bosch Platinum +4 spark plugs on the older 92-96 F150s? I have heard that they didnt run very good on these models. Anyone got any info...

 

IMO Platinum spark plugs are a waste of money. I just go for regular motorcraft spark plugs.

 

Bosch Plats (in my experience) are good for 4 cylinders and maybe some 6's, but don't do the job on V-8's. BP's just don't have a long life span nor do they offer any mileage perks.

 

i have always used champien in my fords and alot off good mecanics have told me nothing works as good as a champien in fords....

 

I have yet to have a problem with AutoLites, still made in the USA
http://www.autolite.com/ I've been using them in everything but the lawn mowers.

 

bosh is crap for spark plugs, use motorcraft in your ford!

autlites are good too.

 

"The Autolite team manufactures Autolite® branded spark plugs and ignition wire sets, and provides plugs to leading Original Equipment Manufacturers like Ford Motor Company and General Motors." (Autolite website)
Sounds to me like its OEM

 

Bosch plugs DO NOT run well in Fords. The best plugs you can use are Motorcraft double platinum!!

 

I've used Bosch platinums in both my '93 5.0 F150 & an '86 Mustang SVO. Both ran poorly with them. I've had the best luck with Autolite Double Platinum.
