Personally, I stick with the OEM parts but that's just me.....changed the ones in my '87, last month and put the OEM's in there as well as the '95.

"Thanks for the input, I had bad luck with the bosch platinum 4's" ...ive never used the +4s...just the "regular" bosch platinums.....had em in my 90....my 91 (which was a 351w motor) and in my 88 town car,all had a msd streetfire coil and ford racing wires,never had any problems with this setup
What do you guys think, Am i oging down a bad path here?[/QUOTE]Comment

I tried the Bosch Platinums in my VW Beetle and my s10. Ran worse in both. Went back to Bosch Super in the VW and I actually had US Autolite in the Chevy. Boring old Motorcraft copper plugs work really good in a 302.86 Lincoln Town Car (Galactica).

its takes more "energy" to fire a platinum plug than it does to fire a copper plug,hence the addition of a "hotter" coil....without a hotter coil,the platinum plug will not fire properly(low spark)therefore not burning the fuel as efficiently,resulting in worse fuel mileage and other driveabilty issuesComment

The platum electrods will burn hotter which can cause issues in older engines not set up for them. Some get away with it some dont.
Personally I was running Bosh super + copper at one point. the next set purchased they changed to being coated with plat retinum. Noticed indications on the porcillen of begining of preignition so dumped them for something else.
Others have gone to the new platum plugs at the shop next door and have had issues on older engines. Mabe some of it could be tuned out backing off timing or something. Another thing you might be supprised even with high end plugs after a couple months how much better your vehicle might run with new plugsScars are tatoos of the fearlessComment

True but I think its retnum (sp) hence iridium as Bosh calls it is a mix that allows platnum to fire at lesser voltage.Originally posted by t65neon5 View PostScars are tatoos of the fearlessComment
