I bought Denso Iridium spark plugs for my TT. The paper it came with said to gap the plugs .044 if you have mild to heavy mods, and to gap it .05 if you have heavy mods with upgraded ignition. Has anyone installed these plugs in their car? These numbers seem pretty high to me. I have the HKS DLI and Apex'i ignition timing control for ignition upgrades, and my car has everything short of upgraded turbos. I don't want to have to go through trial and error. So would someone please verify that the recommended .05 gap is good. Thanks.
