I am running a Cobb stage 2 tune OTS tune. H

Here are my mods

Magnaflow downpipe back exhaust
CRX intercooler and piping

Still on stock air filter and downpipe.

Car has run fine since new. It has just under 7K miles. Recently my check engine light came on and was showing code p0303, misfire in #3 cylinder. I have seen threads discussing this issue. I can notice a slight stumble at idle but it appears to run fine. With the mods I have do I need colder plugs or need to change the gap in my stock plugs?

^nope. Most of my driving in it is local and less than 20 minutes. It has also been pretty dry here.

Reason I ask, experienced this one after a long highway drive, ~3hours, in high humidity. My thoughts were after marketing intercooler was too efficient and pooled some water in there. Issue was gone next morning and could not reproduce it
