hey, has anybody ever used the denoso iridium spark plugs, and do theay make a big difference?

 

if your not running boost or nos i don't think it makes a significant difference.

Would it make a difference running NOS. I cant really understand how the spark plugs would make a bigger difference running NOS over stock.

 

running the "correct" plug could make a big difference safety wize.

BTW tt.net had a thread on one guy who switched to these plugs on his TT300z. Seemed to like them. But again that's on a turbo.

 

ok your going to get into a pissing match about this now too??
if you run NOS the cyl/combustion chamber pressure will increase. the increase pressure *may* blow out the spark. the denso iridium plug have a very small center and that exposes the mixture to more of the spark. the iridium is also supposely more conductive. also it depends on how much nos your running...lower shots should be ok..higher shot would require a little better conductor.
i bet u want to see a dyno chart or something now right? no i don't have one..but if u don't believe and don't feel like taking advice then that's fine. i really don't give 2 $hits. this petty bickering gotta go. i'm sick of this BS. if you want to put 200shot of nos into your car then fine..go do it. if u want to run 1 wiper..fine go do it. if u want to run 20 inch rims..fine go do it. no one is stopping you. if you feel like running slick tires on the street..go ahead and do it. i'm not going to stop you..i don't even care...but if u go and tell another BBS member to do something that you think it's cool you should also let the person know the pros and cons of it and not becasue it look good.

well it just happens I have one ;p take a look, i was just debating if it was worth like a few hundred for the preformance.

note the car that was dynoed had a bunch of other mods, and it was a honda. not sure if ti'll make a diff on the max?

 

well looks like it makes some power. so it's up to you if you decide if u want to throw down the $$ for them.

dan has a good point. if you do a % difference calculation on the two HP#. It comes to ~5%. also note that the atmospheric pressure and temperature are not the same for the two runs. This results in different quanities of air via density differences. If you do the calcuations to correct for this it drops the difference to ~3% wich is within the acceptable degree of error for a dynometer.


personaly i'd rather **** my money away on another tank of gas....

 

How ya been? I finally got my fog lamps on my car, K&N air filter, and my subs in the back. I forgot to ask you at the max meet in Long Isl. what sparkies you'd suggest to use. Which do you use? Thanks!
