Okay, I am trying to decide which Sparkplugs to go with.
Should I stick with the Original OEM Audi Plugs (NGK PFR6Q)
which my dealer charges me $18.95 a whack for or should I
try the DENSO Iridiums IK 20 that I can get for $12.99 at
Autozone? I heard a lot of good things about DENSO but don't
have any personal experience with them. I thought the price is
a bit steep until I called the dealer and they gave me their price
on the Platinum NGK's... Outrageous!!!!

Also anyone have any idea what the proper Gap size should be
for a 2001 Audi Quattro 225HP Coupe? Seems nobody knows
this simple question. Even the dealer. Which makes me wonder
about him.

Thanks for your advice and help!

 

Okay, I am going with the Original NGK PFR6Q Sparkplugs. Found them at Advance Auto for
only $9.98 which is about half price from what the dealer charges.
Also FYI the Proper Gap for the Audi TT (Any Model with the 1.8T) is .032 or .8mm in Metric form.
