Note that the OEM NGKs are actually sold as normal ones.Yup...x2. It seems our cars run best on the OEM NGKs. I heard of some success with copper plugs, but they need to be changed more often.
I have an AEB with a Wett chip, does that change anything? Should I get plugs that are one heat range cooler??OEM 1.8T Plugs:
AEB -- Bosch F7LTCR -- 20,000 mile service life
ATW AUG AWM -- NGK PFR6Q -- 40,000 mile service life
(The different plugs for the AEB are probably due to the different head, valve diameter, & intake runner geometry on the AEB vs. the later 1.8T engines)
I have a Wett chip, too (0.9 Bar) and I use the OEM NGK PFR6Q's. I never see any significant knock-based timing retard (always less than 5 degrees & typically zero), so I haven't messed with a colder heat range. (I hook up the vag-com at least once a month and log data)I have an AEB with a Wett chip, does that change anything? Should I get plugs that are one heat range cooler??
because NGKs simply kick the crap out of bosch plugs (see the breakage issues in other threads)I wouldn't trust everything that you read in Chilton's.
I still am stumped why a German automaker would use a Japanese plug?
Why are you posting blank boxes?WTF, is my typing invisible???
Wow that really sucks. Any word from Bosch?Please read this before you chose your plug.
I don't want you to go through the pain I'm going through.
