I have purchase 3 set of AR-13 plugs this season and each set has been in the engine and iI check my plugs after every race that I have attended and after every race there was a problem with at least one plug mostly the porcelain was cracking.The saving grace of it all was NAPA took back each bad plug and gave me a new one.
