TR55 V burned after 500miles
. Gapped at .55. At least my TR55ix last 3000miles
...just to let you know that there is a difference between the life of the two.Too bad I've lost an hour changing my last set. The most boring thing is that I am parking the car for the winter this week(30mins road), so I have to change the plugs

I guess my tune is way too rich, am I wrong?
