HKS Spark plugs???
 

I checked out some Evo X's mod list's and quite a few of them listed these Hks spark plugs. I was wondering what you guys think of these? Good idea? Anyone tried these yet? I'm probably going to order some soon. Mike...Brian...? Thanks in advance.

Not going to make any power for mere mortals. If you'll be running things nuclear hot you could put in factory X plugs.

What if i ordered the 1 step colder Hks plugs? So X plugs would do me some good?

You would be poorer and no faster.

RalliArt plugs will be fine for you up to and over 300 whp. EVO X plugs like I said if you turn all the knobs to 11 and are running up to 500 whp. Beyond that, sure, spend some money on some HK$ plugs.

So what heat range should be used once a RA is making around or a little more then 300hp (in example 9 or 8 heat range)?
