I own two B5's and a B7pro. I almost feel like these engines need a hotter plug. I don't dispute it because of what everyone says here. When my motors are running good they temp at 180 or so. I realize my gun could be off.
Long story short.....has anyone experimented with a hotter plug? Is the 99t the next hotter plug? Is that how it works?
