Default Spark Plug Gap

I just bought a set of Iridium plugs for my '97, can anyone tell me what they should be gapped at?

The proper gap is .050". Check out this website: http://www.ngk.com/results_app.asp?AAIA=1358579

Gapping any iridium plug is a very sensitive operation. It is not recommended with traditional "garage" tools. Any gap +/- .10 from the spec should be fine.

I also just brought the NGK Iridium Plugs for my 2003 Corvette Coupe. My car currently have 8,500 mile on it. Before that, I had the Bosch Platinum 4 install at 7,000 mile. Were you able to tell the different in the "Performance at all with the NGK TR55IX?" This question to anybody that can help.

Thank You
