Do spark plugs really make a difference??
I saw on an add for some spark plugs that they gave a race honda civic another 59hp. Then it went on to say that it gives an additional 10-25hp on a wrx application.
This obviously can not be true. How much gain would I really see from a nice set of spark plugs ??

Use NGK coppers, part number BKR7ES-7 or -8. Experience less detonation. Make power with other mods. Spark plugs themselves don't make power unless you compare them to improperly gapped plugs.

NGK's website doesn't recognize that part number
NGK IX iridium BKR6EIX $6.95
NGK Double Platinum PFR6G 11.71
NGK GP platinum BKR6EGP $2.68
NGK Traditional spark plug BKR6ES $2.24
NGK Traditional spark plug BKR6E $2.24
That's all I saw on the NGK.com site.

The -X number refers to the height of the electrode. -7 comes at like .025 and -11 is like .044 or something. On a WRX, you want to be gapped about .026-.028, so you want -7 or -8.
