Bros, wanted to share with u what hap to me and my ride...
I went to kranji loop with a e46 valvie at UM2 to have my spark plugs replaced from my denso ik22s to the much talked about volkers, i think i had the 7zx-8...or something like that...
initial drive was idling markedly smoother and throttle response livelier.
but after 4 weeks, idle started to be jerky, normal idle aircon on is about 800rpm but at traffic lights sometimes shoots down to 500-600 momentarily and maintains 800, possibility of misfiring apparent.
drove for another 2 weeks with intermittent problems on my a4 1.8t with numerous occurrences of the aforesaid problems.
went do to my usual workshop on saturday and had my original IK22 densos fitted back, no more problems!
went to google a lil and found this article in a local forum....

Hey bros,
something to share with you all out there about volker iridium plugs. I got a set from the authorised distributor all the way in Kranji Loop for my ride 2 months ago. When I bought them, the first impression I got was that these plugs were finished poorly as the ground electrodes on all 4 didn't look uniform. Anyway, I thought I shouldn't let that bother me. So, I installed them (carefully torqued with my torque wrench) and drove around for about 2000km. Recently, my idling seemed quite erratic and so today, I decided to take them out for an inspection to see how they were doing.
Among other things, I used my multimeter to measure the resistance of the plugs, from tip to nut. All 4 plugs registered way LESS than 5k ohm! These plugs supposedly have got a 5k ohm resistor in them. One gave a reading of 2k ohm while the other 3 measured 2.2~2.6k ohm. Obviously the resistors in the volker plugs failed.
My used set of denso iridium IK20s all measured 5.1~5.5k ohm. Says a lot about the quality of volker iridium plugs. So much about being able to last 160,000km!
It's back to denso iridium for me..... this time VK20. And lo and behold, the engine became smoother after that.
