HKS Iridium Spark Plugs <--- what gapping should i install them at??
JDM Integra 1998 GS-R Transmission

i searched but did not find much about the kind of spark plugs i have.. unless its all the same??

 

.030" unless you still have misfire and in that case, go in .002" increments until you eliminate it.

I wouldn't use those spark plugs if I were you, though.

why not use those spark plugs?? sport car motion says i should do .025.. .002 incremets as in .032, .034. or the opposite. .028, .026

 

I wouldn't trust iridium in a boosted motor, but that is just me. They will hold up fine, but they are really overpriced and the small piece of iridium on the electrode could melt off into the combustion chamber causing a mess.

I mean keep closing the gap down from .030" in .002" increments. It all really depends on the setup and .030" on your setup should be fine.

Iridium is something like 6 times harder and has a melting point some 1200* higher than platinum. If you reach the point to melt an iridium spark plug you probably melted your piston long before that. Iridium plugs are fine for boost(unlike platinum). They last 4-5 times longer than copper and require less energy to make more spark. Real platinum plugs are the ones that are over priced. And besides you talk about melting pieces flying into your engine? What do you think copper does? That's why they don't last nearly as long. Little burning pieces of copper are flying around inside your engine. That doesn't seem harmful but some how a spark plug that doesn't do that does? If you are going to say get copper plugs then at least tell a truthful reason to.

Like I change my plugs every 10k anyways and iridiums aren't worth the money. In that case you would be correct. But saying they are overpriced hunks of garbage that don't work. Hmmm I wonder why cars have a service interval of 100,000 miles now when it used to be 15,000 just a few years ago and 30k with the advent of platinum plugs.

I don't use iridium plugs. But I change my plugs more often than I need to. But I know for longevity purposes iridiums are way better and don't really cost that much more.

TTOP. Iridiums can be a pain in the *** to gap and if you like to change your spark plugs every 5,000 miles they definitely are not worth the money. And if you are not running insane amounts of boost and you have the right plug for the job than .030 should be ok(operative word should ). Unless you just have weak spark of course then you will have to close the gap up a little bit.
OK I'm done. This is my one useful post for the month. Now back to talking trash. It's much funner and I don't have to think so hard to do it.

thanks but gapping at .030 ic.. iono why sport car motion told me .025 ??

 

I'm pretty sure your tuner knows more about your car and setup than I do and is better at it then I am. If he says gap it to .025 then I would listen to him.
