[Tennessee]

What Spark plugs to you guys suggests running in such hot temp.? I had to take my Audi in for the Check Engine Light, and they tell me that I had a few misfires.. Which in turn is gonna cost me $437.00 for a software upgrade and a decarb combo?

Upon reading other posts some have suggested using different plugs, but the posts that I found suggested plugs for colder wheather more than extreme heat.

So, what plugs have you had good experience with in Hot wheather?
