Andrew asked: "It's time to replace the spark plugs and front brake pads on my 2000 A6Q. What's the current "state of the art" for both?" If it's a 30v V6Q, NGK BKR6EKUB (3584) is the recommended plug. Bosch lists no plug for that app, at least on the Worldpac site. List is $12.30 each, but there's a LOT of room on that price. HTH, John
