They've got close to 50,000 miles on them, I pulled the left front plugs last oil change and the plugs are burning great with no change in plug gap. I didn't pick up any noticeable MPG's or HP but the engine runs much better on crap gas then with the stock plugs. Are they worth the extra cash? To me yes, because I can run cheap 87 octane gas with no loss of power.
