Message the shop where I took my car to installed the PFR6B-11B's in 4 cylinders and some other heat range ones in the other 2. They showed light signs of heat damage/discoloring so they were a hotter plug.

After installing the correct ones and gaping to .035 my car started up quicker and idled better.
