My 2000 with California emissions (regular cat and then two pre-Cats at the exhaust headers) would only run properly with the oem spec NGKs. Threw Bosch in their once and it ran terribly.
Pros: ran properly with NGKs
Cons: ran terribly with Bosch
The new ignition switch is in. The spark plug wires are Bosch copper and now have the Bosch super 3 ground electrode plugs installed. So with a fresh ignition switch that eliminated the odd electrical changes we were seeing in the dash lights, now stronger cranking and it does run better.
Pros: stronger cranking, runs better
Vehicle:
Volkswagen
I also added bosch sparkplugs 4 months ago, and also have some stuttering.
Cons: some stuttering
Bosch W6DPO. They’ve always been expensive, but now stupidly so. I’m not paying $250 for plugs, either. The DENSO IW20TT you referenced is a perfect replacement because it’s the exact same heat range as the W6DPO.
Pros: perfect replacement, same heat range
Cons: stupidly expensive
Ever since Bosch moved spark plug production to Russia, the quality has been sketchy.
Cons: sketchy quality
That said, make sure they use quality parts. BMW/Bosch spark plugs and OEM pulleys (and belt) are a must. NGK plugs are cheaper and don\u2019t last as long. Same goes for off-brand belts and pulleys.
Pros: quality parts are a must
Cons: NGK plugs don't last
Went with Bosh double platinum plugs at 60,000km when I notice a stumble at idle and that's the interval for change. I instantly went from best of 9.6L/100km to 7.8L/100km big difference in performance and smoothness and i prefer a German plug in a German car with Bosch electronics.
Pros: improved fuel economy, increased smoothness, fixed idle stumble
Vehicle:
Volkswagen
Mileage: 60000 km
I'd stick with the WR6DPO Bosch. Not sure why but they just work with no questions.
Pros: they just work
Part number: WR6DPO
I don't say for 100% sure but my understanding is that Bosch and NGK are the ones you should use
