quick note that after a 30 mile run this morning, I do notice more snappiness. It is kinda weird, when I originally put the 605'* in to get by until I got another iridium I noticed it was alot peppier than usual. When I stuck the iridiums in, we took off on a little trip of about 160 miles for the day and it didn't feel the same. I'll be leaving the 605'* in.

OK.. So I went to get plugs for Tamara'* 95 N/A @ Crappy Tire.. deciced to get NGK "G-plug I think.. platinum" and it stated already TR55GP as stock.. err.. so that mean it'* already one heat range cooler? Also I notice there was a few variance on TR55'* For irridums there'* TR55-1A TR55 XXXX <-- something else in the end. WTF

Big difference, and a waste of money when you have to change out Plats in a month for Irridiums.
Copper plugs are preferred over Irridiums in Supercharged cars. They dissipate heat more quickly.
NGK TR55 gapped at .055" for one heatrange colder
NGK TR6 gapped at .050" for 2 heatranges colder
Or the Autolite plugs (copper).
