Spark plug Horsepower comparison
Just found this very informative dyno comparison of various spark plugs. Includes NGK laser platinums, V-power, G-power, and Iridium IX. As far as performance is concerned the ranking would be:
1. Iridium IX 2. Laser Platinums 3. V-power/ G-power http://www.sparkplugs.com/sparkplug4...fid=0&KID=3095http://www.sparkplugs.com/glossaryImages/499.jpg |
thank you man. good find. 35$ for NGK Iridium IX on ebay!
|
I"ve heard and read that using anything outside of the recommendation for 'stock' purposes are a complete waste and can fudge the engine up.
|
Dude whatever, a racing strip pwns the HP given by spark plugs. 25 WHP baby! :yeahright

That was very interesting. I have the Iridium IX and have been loving it. Glad to see they are the most consistent out of any of the plugs.
Nice find on the chart, but I would like to see the same chart with the VQ engine. |

I just did a recent tune-up and I was using the Iridium IX and I also felt some difference. I lost some low end and had better mid range and high end power. The car also warmed up In less than a minute cause they are so aggresive with the heat. I know that Iridium Is a quality type of metal that excepts high excessive heat and The car feels more torquey.

Meh, i noticed no difference when i went from iridium to platinum. Anyone heard of the "Placebo Effect" I think thats mostly what you guys feel, because personally my butt dyno is pretty in-sensitive, i barely noticed a difference when i got my y-pipe, although i noticed it a bit when i took it off.

i use NGK iridiums and works great wouldnt change them

When i put on my coppers i noticed about a 100hp increase. I could now spin the tires through all 5 gears. I also get about 50mpg now. What i really noticed is that i could stop faster and corner better.
Bottom line, no one can tell the difference between those SP's. Somebody should do the pepsi challenge, but with spark plugs. |

What I meant was that the car ran much smoother and the throttle response seemed to be better. Than again, the plugs I removed were Densos and they were pretty fouled. You definitely won't feel any change in power from using different spark plugs. |

Another idiot adding crap posts to threads. Good job buddy. Aren't you supposed to be doing your homework or something little one?:laugh:

Comparing a boosted application to an NA app is apples to oranges. Even then, less than 2% difference = FTL
So I'm with 'the little one' on this one. :rolleyes: |

You agree with him that a racing stripe increases power by 25whp? You guys should get together and play some Pokemon, or whatever else you little ones like to play :laugh:

Crappy post for a crappy thread.

lol not much help for us NA but its good to know, those NGK Iridium are freakishly consistent, I think they would be the best investment, im surprised at the Denso Iridiums performance thought they would be identical to the NGK and I would never buy those pulstar plugs anyway
|
Less than 2% gain :spit: I gain more w/ a GAB.

You might want to take a look at this thread? http://forums.maxima.org/showthread....light=dyno+gab By the way, butchering your air box is not a smart thing to do. Our stock intake is superior to any after market intake. Also, 2% gain is excellent for $30. Then again your talking about ghetto air boxes. lol:laugh:

I've dynoed my own gab and have gained 9 whp with, as well as 3 other members as well. 0$ for 9whp gain, seems like a no brainer.
Another item, right now I am a supporting stock airbox member, BUT, I'm not saying it gives you the most power, I'm just the one who is trying to gain the most with it by modifying as much as I can in between. I have seen the stock A33 airbox support as much as 230 whp, and the stock cat-back support up to 247whp, so I am pioneering my way to see if I can at least fit somewhere in between that. Also, this convo is not 4th gen specific, but it has more to do with Maximas than this thread does. |

Someone wasted a lot of time, A LOT.

Man this thread only promotes the ricer effect. you know what I mean the "I put an intake on my car Civic and "added" 20HP it is so fast now!!!!" sure some different spark plugs work better than others but unless you have a miss fire or something of the sort you will most likely not feel a difference. the charts showed a 1HP gain. if you can feel that you are somethin else. |

Way to go jumping at people's throats and name calling because they disagreed with what you posted, which isn't even something that you did yourself. That is the best way to gain credibility in anything you do, so please continue. |

Looks like someone sneezed when they had the crayon on the paper... I apologize ahead of time if I'm wrong, but I've never seem anything like that before. I'm also having a hard time believing that a GAB adds 9whp. All the posts that I have read about GABs seems to indicate that its not a good idea. |

Whats up with the loop in the graph between 4500-4750?

That loop can be seen in all auto dynos, it's the LUTC. A34's have a LOT more issues with that than I do. At the time I was a rookie in the dyno game and didn't let it shift correctly. That is irrelevant since the dynos were done all after another and actually show a change in power with solely the GAB. Read the entire thread and see what and how I compared the items.

i would definately run the stock oem NGK plugs. theyre expensive but also have longevity on their side

and Nmex, it seems like there might be a fan club on the rise!:bowdown1: :laugh: |
It’s SR’s fanclub, I just live in it and keep gaining everytime I dyno. :ben:
