i just wanted to know or inform anyone out there of the bosch 4 prong spark plugs. i wanted to see if the 4 prong spark plugs made a difference in acceleration time (not necessarily horsepower). since it was 4 prong i had the idea it would give a better spark but i kind of came on the discovery that it may actually rob your power. how i feel this is that my mom has a 96' civic dx and she had traditional ngk spark plugs. now with my car being new and having a little bit more power i was wondering why her car would get up and go while mine took a while to even start its acceleration climb. (added note: i have an injen cold air intake while her car has no mods at all.) now the funny thing is when i put the 4 prong spark plugs in her car, her car began to "drag" and didn't just get up and go like it used to. so beware of the 4 rpong spark plugs. just wanted to know btw if anyone had an idea of which spark plug would actually give a true boost- even better then stock; and more likely to add horsepower if any at all.

well, it's all a matter of opinion. Some people will tell u that spark plugs don't affect performance, acceleration or gas milage whatsoever. Others will tell you that they feel a difference. In my opinion, I could feel a slight difference and a up in gas milage when I changed to iridiums ... but that's also just my opinion.

yeah i switched from the factory DENSO plugs to NGK R's and i noticed a little difference in 1st but only in the initial acceleration through about 3000rpm

so hypnotic where can i actually find these ngk r's and how did you hear about them? what mods do you have on your engine because ive looked around on the ngk's and one site actually dogged them out.
i saw a pair of IX iridiums from ngk direct but i dont know if the R's would be better? anyone have an opinon (more importantly fact) on this one?

....and they say to really use the R's is when you are using more of a racing application (duh) but otherwise dont use. now ill be running everythign stock except for the cold air until i get some more bread (money) so i dont want anythign to go a little wrong like knocking or anythign else that sucks. anyway someone let me know please
