Anyone run these plugs? My 350 is supposed to have a few hp upgrades and I was wondering if I should run these or just the stock AC delcos.

No no no no no no bad no. :doah:

You want stock type plugs with normal electrodes. The fancy platinum-tipped snake-tongued spark plugs exist only to separate money from your wallet and more often than not run worse than stock.

(Mind you, years ago I had a beater whose #3 cylinder was so leaky that a regular plug would foul in a few days. The Splitfire was the only plug that could burn through the oil and stay firing. In that case it was worth it ... but the motor eventually imploded and I threw the car out.)

what they ^^^ all said.. leave the snake oil for 2 $ hooker night..
 
I have redone so many customer done gm tune up jobs cause of skip in motor with fresh bosch plugs.

tell them every time if my ACdelco plugs don't fix it you don't pay .

fyi I get paid everytime :D

I even tried splitfire in a 96 vortec 350 I had and skipped under load at highway speed. pulled them with under 100 miles on them and ACdelco back in and 100% fine .

only thing a splitfire did any good for me on back in the day was my 87 Suzuki lt500r QUADZILLA atv . different story now with race gas and jetted in 100% and hp goodys . but it now runs $10.00 each ngk iridium plug and no problems since them $$ plugs .
 
yup, installed 3 set's of MR43T's today as a matter of fact...


I swear, I must install about 800 a yr easy.... :haha:
