Spark Plugs Recomendations

I have to replace all my spark plugs in 2.5K miles at my next oil change interval.. not looking forward to it. What spark plugs are you guys using for those with tuned M157? OEM or should I go one step colder? Gapping? Looking for suggestions as I have no idea.

Eurocharged tuned 2014 E63.

it varies by tuner... for me, renntech says oem. for eurocharged i think they have different recommendation depending on which tune of theirs you have

I have 14+ OEM on a eurocharged stage 2 tune. .024" gap with a feeler gauge, don't use those coated round gap tools from a parts store counter as they are inaccurate.
