BEST plugs I have EVER TRIED!
I have been using Be1H10's in my 2003 6G74 Diamante V6 for the last 6 months and can say they are the BEST plugs I have EVER TRIED..!! There is a REALLY NOTICEABLE increase in both POWER and in economy at cruise throttle openings, and a very strong steady idle... Now I am waiting for a set of IBe1H10's to arrive...can't wait to fit them!!
