I spend all my time in the Diesel discussion, guess I have to get out more.
Here is a thread from tonight that discusses this exact kit:
Run, don't walk, to the dealer, get a K1 kit!!!
A link in there will take you to Fastlane (sponsor of this board we are using - ahem!) where this is $15.00, a little better than the $25.
I will be doing this to two cars of mine in the next few weeks.
I'll take pictures.
