0.44'' is stock gap and I believe heat range 6. People dog Platinum plugs but the truth is for N/A their great. I ran quad electrode Bosch platinums and noticed a slight bump over the stock single electrode. Iridium's IMO are a waste of money for N/A unless radical compressions.
I am curious how well the new Pulstar pulse plugs perform on a 1uz.... but at $20 per plug they better be able to wash my car afterwords lol.
