I just bought some NGK iridium IX spark plugs for my GSR n/a. People on other forum told me that these spark plugs aren't good for the vtec motor(performance-wise) Do to the low heat.

Can someone tell me which spark plugs are good, I have been told NGK laser platinums are good for my n/a GSR. Any other comments on that or other suggestion on the SP that I have already bought. Don't want to install them if they're gonna grain on my performance.

 

NGK copper all the way baby

 

one spark plug makes no better power then the other as far as good brands in the same heat range go. The only way to upgrade on the plug is to replace a worn plug. I hear that you get better response by lining up the spark plug to make the gap face the intake. This kinda makes sense seeing that the gas doesnt have to find the spark so to speak. I have never tried it, but I will one day.

 

Index your spark plugs - this is an age old trick that is good for about 1 extra pony. The idea here is to "aim" the open end of the spark plug terminal (the gap) towards the intake side of the head. In order to accomplish this, simply mark on the plug a small line to indicate where this gap is, and install the plug as normal.

Try to line up the line with the intake side as best as you can. It may require buying 2 sets of spark plugs in order to do this, but hopefully you'll be able to do this the first time. Be careful with aluminum heads not to over tighten, as that could lead to a costly repair.

There are some other "tricks" as well, but I'm not sure about what you'll really gain from them, but hey, like it says it costs "practically nothing".

 

yeah it's a little hard to do on a honda/acura. you would have to mark your socket I think to know for sure. It's more of a V8 racer trick. They also make washers in different sizes to help you index the plugs. (think about it, they all won't be tight right when the electrode is facing the intake side of the chamber).

Anyway's, I wouldn't run anything but stock in a GSR, the factory put the best plug in your car already.

 

I would disagree with the factory put the best plug in it there, any more than I would say they put the best available OEM tire on it. They use platinum plugs to extend the maint interval, and long wearing, sorry ass all season radials instead of a performance tire. I don't know if it is better, but in theory, a copper electrode would work better than platinum, and is way cheaper. I know the cheaper gets srt of canceled out by more frequent changes, but it seems to run better, which also does not mean a lot either, my 2 cents

 

most OEM spark plug wires good!!

 

I don't agree, I think NGK is one of the best plugs around. The tires the GSR came with are good tires for the car's performance. It's not an NSX or something. Michy's are good and the tires that came on the GSR/SI are pretty soft for a all season tire. Mine only lasted about 20k with regular rotations and I'm not a tire spinner. Sure it sucks on wet surfaces but it's made to drive in different conditions. If it was more high end it would have high end tires. Sure copper in theory might work better but it doesn't last like platinum and ppl aren't willing to pay for plugs every 30k anymore.

 

Dude, people are lazy. Michelins are good tires, but those oem ones suck ass, they are not good for anything. NGK's are what I run

 

Yeah the OEM ones aren't that great but better than the firestones that come on the dx, ha ha
