What, nobody likes old-school Champion coppers? I've been running the same set for about 5 years now in the 454. I pulled em out a couple months ago and gave em a good scrub with the wire brush and tossed em back in again. No problems/wear/etc.

Runs like a champ!

A friend of mine runs the E3 things in his big block donkey he likes them but it’s a ford so who knows lol

Autolite or delco. Whichever is on sale. As far as having a longer electrode, seems the longer ones would produce a tad more compression because it makes the combustion chamber smaller. Just my thinking.

I tried them once didn't do a damn thing different than the NGK's except take my money, they're just a gimmick IMO...

Oh yea. Maybe boosted I could see but N/A not so much. I ran dual tip Bosch in my Audi on 25-30 psi of boost it made more power on the awd chassis dyno with them in it

Yeah maybe boosted, I'll have to ask a friend of mine if he tried them, he's got a 600+ with a 1471 and a hat dynoed at 1325hp..

Nice. The NHRA guys brag them up but they use them once but then again they are boosted and shoot liquid fuel from the pipes lol and I guess the stay lit.

Well, maybe they are good in that environment who knows, my friend runs gas and it's in his family day cruiser and it just runs all day long, different world there.

I've never tried bosch platinums in a SBC, but I did run them in the last car that I ever owned... 1997 dodge stratus 4 door. bought it wrecked, had a buddy that does autobody do most of the work fixing it, and then drove it for like 8 years.... managed to put on about 130k miles in those 8 years... averaged about 35 mpg with the best I ever saw for a tank being 46.7 mpg. When I finally sold the car I got $500 and it had around 210k on it. Never had a problem running those bosch platinums. It also had a cold air intake and straight pipe exhaust with an annoying ass fart can on the back... it was awesome... I miss that car

Have them stock in my Corolla 130k miles and climbing, this is where I think the iridium is a benefit.

Put bosch plat. in a v6 camaro I had back in the day, first time I ever saw a efi car cough,pop and stumble. Replaced them with standard delco car ran fine.
