According to the Bentley manual, the gap setting for the original Bosch WR7DC (copper) plug is 0.028", or 0.7mm.

For anyone experienced using the NGK Iridium equivalent (NGK BPR6EIX) would the gap setting for the NGK be similar?

Thanks.

In case this thread is referenced in the future, here's the response from NGK on the question:

Hello,

Thank you for your inquiry. Although it requires less voltage to jump the gap on Iridium plugs, the gap should be set to vehicle’s specification.
