I wouldn't suggest getting any witch spark plugs. You could probably search though because I'm sure you're not the first to ask this question...

If you just have those mods and don't really run a large amount of boost then the standard copper VIII plugs will work just fine. If you are having problems with blow out or want to get a nicer plug that won't need replacing so much then go for the NGK Iridiums.

The BR8ES seems a bit on the cold side for 25 PSI. Consider the BPR8ES, or the BR7ES instead.

NGK BPR7 part number 5534, they will be fine for your setup and are about $1.50 each.
