'02 C240 2.6L MB wants $16.5 per spark plug...where do you get YOUR plugs

So, where are you getting your plugs and what brand are you using?
Also, is the plug gap for the 2.6L 2002 C240, 40 thousandths?
Thanks!

Based on things I've read on this forum, I decided to go with the NGK Iridiums, but haven't yet put them in. I wanted something with a really long life, but my general rule of thumb for spark plugs is: if you're satisfied with the performance and longevity of the plugs you have, replace them with the same. (If you want to do that, pull one to get the numbers off it so you're sure you're getting the same replacement.)
Good luck and enjoy the ride,

Greg
