first off... if you go advance auto.. think retailmenot.com and snag something like the $20 off orders over $50 or 30% off etc. Just because there's no need to overpay. Wires.. I kinda like AC Delco, or ... can't think of them..but they are lifetimes .. crap... had a set on the last Regal (#7) and a ..... wait.. Autolite professionals. Cheap.. and lifetime replacements. Gotta love that.

I try to stick to what's available and has the good warranty.. it's like the three year warranty on Moog wheel bearings. can't go wrong when you own a W body.
