Pretty sure it had original plugs in it, replaced those with some autolites that were on sale, soon to put champion coppers in it though (personal preference).
I use NGK's, and they seem to do just fine.
Yeah, I'd rather use some cheap BOSCH SUPERS or other $2 copper plug than any Autolite.
Oil change every 5-7k miles Mobile 1 European Formula (0w-40) Seafoam every 5-6 months New NGK Laser Platinums Plugs (500mi ago) 1 new coil
Sometimes you just have to try a few sets. I have a '97 Jetta which had NGK plugs in it for close to 4 years. I went through two sets of NGK plugs and couldn't get the car to run. I switched to Bosch and it started right up and ran fine.
I run the DCPR8EIX and they are great. No need for 9's for me.
NGK are a good spark plug brand.
NGK BKR7EIX is a popular plug for 1.8T and 2.0T, but it is one step colder in the heat range. Fine for those whom don't see freezing and below temps.
Lesson learned: DO NOT EVER EVER EVER USE BOSCH PLATINUM (STANDARD TIP) SPARK PLUGS IN YOUR VR6 ENGINE.... THEY JUST DON'T WORK!
I didn't know any better and used ****ty autolite spark plugs, and everything was fine and the misfires went away... A few days ago I noticed on quick acceleration and around 4-5k RPM's, the engine loses power, accelerates slower than...well, slower than a 2.0 normally is.
