They are trash, IMO. Never use them in your 5.0 or you will miss like a mofo.longfellowdeeds said:are bosch platnium +4 spark plugs any good??? they are quite pricey... and how do they compare to iridium?? thanks in advance!
I was being a little facetious -- Bosch makes more than just sparkplugs, and a number of parts on our cars. For example, the ABS. They're a pretty big company, I'll grant you that their spark plugs are garbage though.madams74 said:No it isnt. This company plays to the tune of ripping off the customers by making false claims. They abuse their name and allow people who are ignorant believe they are buying a superior product. This is abuse.

Not to mention if the spark has choose between 4 electrodes to arc to then there's got to be some hesitation in it's quest to find the "path of least resistance" and some cross-arcing going on in there and that's gotta make the spark less powerful and cause some kind of resistance I would think.Speed_Demon1965 said:Bosch plugs suck. 4 electrode posts...please. The spark is going to go the only ONE post at a time so what's the point of 4 of them? About as bad as "splitfire" plugs. I would use a good set of Autolites or use some Iridiums. Iridiums may not do much for a stock engine, but their life is much higher than standard copper plugs.
