Until about 5 hours ago, i had bosch platinum core, resistor spark plugs...

i went to kragen and bought 8 of those NGK plugs, and now my car not only idles VERY smoothly, it seems like a lot of my problems went away!

vibration under hard acceleration has pretty much disappeared!

dunno the beru, i think it's the one in JDC's post?
Not to be negative, but how did the old spark plugs look, and how did they differ between the cylinders?
Before I changed my fuel distributor, new plugs would make the engine run good, but only for a while.

hmm... they didn't look TOO bad, a bit of carbon on em, but that's about it.. i'll take pictures of them in the morning.

the gap on the old ones were also set wrong, they were at .032 instead of .042

the only thing that i really noticed was that the 3rd cylinder on the right had a bit of motor oil on the plug.... after i installed the new plugs, the 380 had blue smoke comming out of the tail pipe for about 1 min straight.

what plugs do you reccomend for a 91 420sel?

what gap do they need to be also? If I buy all bosch parts: new dist. cap, dist rotor, wires and plugs is it good enough or should I buy another brand?

dude... I don't know if you've read the threads in which you posted, but the answers were clearly written. The gap is written in the post just above the one you posted. The other thread said that the Bosch wires go back very quickly... that BERU is recommended. Regarding the spark plugs, this thread mentioned which ones to use or if you can find the no longer made, non-resistor plugs by Bosch.. get those.

should basically be the same for all models... unless it's diesel.

for the parts you're talking about anyways.

Snibble,

Could you please help, what is the product code for these Bosch non-resistor plugs?

Cheers.

I am running Beru wires and NGK plugs on my 560SEC for many years, and feel confident I made the best choice, I have never had problems.

The car has 123k on it, and cruises comfortably even at speeds of 120-140 mph. (When I can find a place to do it);)
