Best Spark plug for Volkswagen Golf

I got the plugs in just fine, and since this was the first time they had ever been changed, the originals were still there. Aside from having the Audi/ VW logos printed on the topside of the plugs' insulators, these are regular ol' NGK PZFR5D-11 plugs (stamped on the metal). The new ones I put in were pre-gapped at .040, and the old, worn ones were at .044 for the passenger-side plugs and at .043 for the driver-side plugs. I'm guessing that the elevated distance/numbers reflects natural wear and metal erosion over time.

I am stage2+ and changed out the coilpacks at the same time that I went with NGK. I never did a side by side comparison, but so far i like the NGK's

i havent noticed any drop in performance..runs smoother though like you said, and a little better fuel econ too

For the misfiring check your spark plugs it can be that simple... i got a mkiv golf too.

Last night I finally decided to trash the bosch spark plugs and installed some new NGK spark plugs and while I had my upper intake manifold off I bought a couple cans of throttle body cleaner and gave my upper intake manifold out and also gave my throttle body a real good clean. It was covered in sludge. But anyways after I sea foamed it a couple weeks ago, changed the oil and filter, spark plugs and cleaned the throttle body last night my car is running like a champ and doesn't feel boggy anymore.

I would also recommend NGK plugs, they are made in Japan and well worth the money.

I just replaced my plugs in an 89 16v yesterday. I ended up getting the Bosch platinum +2. I was leery of the platinums as everybody seems to knock them, but my car runs fine. They were 4 bucks each.

got my f6dtc's at the dealer (only place i could find them), and they were around 4 bucks a piece. car ran like a dream.

i changed the original NGK spark plug with new Bosch super 4 spark plugs. a nice improvement but still far from old good performance.

Put the correct spark plugs in there (NGK BKUR6ET-10 for AEG), throw those Bosch +4 turds in the bin where they belong.
