Confused About Plugs
I bought a low mileage 98 A4 TQ and installed
Bosch Plus4's and it seems to run great. 2 guys
on another Forum say not to use these plugs, now
I don't know what to do. The car is totally
stock by the way. Plug recommendations anyone?
Thanks for clearing this up!

if your car runs right then i woudln't be too concerned. I think some people have had bad
experiences with the plugs is all. A lot of ppl seem to try the high end plugs, iridiums etc, but many also use cheap 2 dollar copper plugs. They don't last nearly as long as a platinum plug or iridium but they work and are cheap to replace.

Platinum plugs won't hold up in the turbo motor
The Bosch +4 plugs (or any platinum plugs) are not okay to use in the 1.8T.
I didn't care for the Bosch +4 plugs in my 2.8 either. The OEM NGK plugs were much better.

I thought it was pretty simple
insert plug A into hole B
and wall plugs arent for playing with.
the tub plug is for draining out grandma's moonshine when she isnt looking.
and finally just say no to Butt plugs.
Oh spark plugs... um buy whatever you find works best from your own experience and searching through the archives. This is discussed every 12 hours.

Here's one of my previous posts explaining why platinum/iridium plugs are inferior to coppers:

On a single-prong copper, I may agree, but multi-prongs easily last that long . . .
for the simple reason that there exist two or three extra electrodes to share the work load.
So, do not sell copper plugs short, because copper is the preferred "work horse" metal for plugs--great conductivity AND great longevity.
Due to longevity, only a few metals get used in making plugs; gold, silver, etc. have no longevity whatsoever despite their greater conductivity.
I have had my nickel-plated-copper Beru Ultra-X's for at least 35,000 miles and they still look and run great--even better than the OEM three-prong Bosch and NGK copper plugs which started to look really ugly before I even got into the 20,000 mile range.
