I just changed spark plugs on my jetta.
went to canadian tire originally to get some NGKs, but they didn't have platinum plugs for my car.
vwvortex people recommended copper NGKs, but apparently they don't last long.
so, instead, i picked up some Champion platinum (not iridium plugs. they are quite expensive.

)
gapped to 0.032 inches.(perfectly gapped from straight out of package).
took about 30 minutes.
old spark plugs looked fine(btw, also NGKs with VW branded), but had some dried oil residue near where it plugs into coil pack.

spark plugs, $18
gapping tool, $5
car starting right up, priceless.
BTW, everyone recommends NGK, and we used to use NGKs only when my father had the shop. are Champion plugs not good?
