[Biturbos4] Spark Plug Gap?

It's the 6418 per the NGK website.

Will do Wilson.  Although until I get a VAG-COM tool, it will be butt dyno.

I just searched on Audiworld and saw that the gap should be .030-032??

The NGKs definitely require setting as their website recommends. 
Interestingly, this is the same plug they recommend for the E36 M3.

The car is currently stock as regards ecu and turbos.
