What spark plugs go in my [DSM]?

There is a great guide written here by MrBoxx of DSMTuners:

You want to go with the non projected type plugs like BR6ES, BR7ES, BR8ES. 

BR6ES = Stock to 20psi
BR7ES = 20psi to 30psi
BR8ES = 30+psi

Non projected plugs help fight against spark blow out in high boost applications.

If plug fouling occurs, go one step hotter and monitor performance and results.
