Okay well basically after searching the better part of an hour through the forums about Irridiums and Bosch 4s, I think that of the two the irridiums seem to be better, and have had a better success rate. Obviously, I'm not going to believe the success rate is about 1 in 2 for irridiums so I'm just going to assume it's about 1 in 4. I have a pair of Champion double plats for replacement but I also was thinking of picking up the irridiums and see if I get a hit.
My question is for those who have got a dead on hit, is there anything NOW that you regret or that has gone wrong since you've got them to work flawlessly? Notice any misfiring or anything of that nature? And I guess did you install in any different way deviating from the 'how-to' already posted? Thanks for reading and responding
