Anyone used "Exotic" sparking plugs?

I went through the "General" and the "Performance" forums and could not find anything, so throwing out to the Crew. What luck has anyone had with new construction sparking plugs like the Bosch Platinum? I know a lot of American metal doesn't like them.
Thanks, Grumppa

I tried the Bosch plugs and found no real difference in driving. I used copper anti seize compound on the threads and turned them in by hand with a piece of 3/8" rubber hose till they started to seat before putting a socket on them. They were quite expensive as I recall.

I have run AC Delco Rapid fires and the Bosch Platinum +4's, the AC's were good for low end and mid range performance where the +4's were better for Mid to high range. Both improved my gas mileage but the +4's were a little better overall. Copper and platinum in a standard plug you will not see much difference but the platinum will last twice to 3 times as long. I will be trying out the E3's this summer as I have heard from some of the performance guys I know they work real well and seem to help with fuel mileage as well.

Thanks for the info Guys. I was just cruising the 'NET the other night and got into a spark plug string of "go-to"s. Made me look here on Mighty to see what there was.
No, platinum pluggies are not cheap, but if they do not give performance problems they last forever. I have had a string of Dakotas... two took them OK, and one just would NOT be happy with them installed. I hear similar tales from folks who own Chevy and Ford iron.
I do not think the Iridium plugs are worth the price over the platinum, and I learned about the "Gimmick" plugs when I was a stupid young s__t (as opposed to a stupid old s__t now-a-days)!! Grumppa

Been running NGK for years, never a problem, long lasting

I'm using Iridium's in the Turbo setup, but this is racing only.

Well Dodge is weird and I have found the same problems with them. The only plug that seems to work right is the copper Champions. Never had any problems with any other manufacturer.

I have run many different types of plugs in Geronimo over the years, the bosch fouled out almost immediately, even with a MSD 5 ignition system and Blaster coil. Right now I am running NGK platinums with a set of Nology wires and an MSD blaster coil - runs great

NGKs ftw. All mitsu's seem to love them.

All japanese vehicles run best with NGKs - don't know why.

Most newer stuff with COP ignition run NGKs, even chrysler products do like the V6 chargers. Nissan used them for years and if you put non NGKs it would miss like crazy. However their newer engines are running Bosch 14mm thin tall plugs with coils half the size of old ones.

The fancier plugs with more expensive metals, like Iridium, make more of a difference on higher compression, higher performance motors, like most newer motors. Lower compression truck motors, like the 2.6, won't see much difference. NGK's are magic and work great.

It seems that one of the biggest benefits of the platinum and iridium plugs is that they last a very long time and never need gap adjustments. With conventional plugs the performance and fuel economy drops off as the gap increases due to erosion of the electrodes. With the platinum plugs you will get longer consistent performance. There may be a savings in the long run if they outlast conventional plugs, say 3-1.
