"I put a set of these in my 2007 A4 Quatro. They worked great for about three weeks. The fourth week, i started experiencing "missing." By the end of the fourth week (as soon as I could get it in to have it looked at). The car was nearly undrivable. I had to replace all four coils and go back to a stock set of plugs. I contacted E3 4 times to discuss their WARRANTY and have yet to get any form of contact back from them. STAY AWAY UNLESS YOU HAVE MONEY TO BURN." posted by: NOT SO HAPPY E3 on May 26, 2011
