I've forgotten, but aren't the oem plugs NGK?
No they are rebranded Bosch...   :smiley:

Well, AFAIK the oem plugs are good enough for VWR's race cars, so that's good enough for me. I just change plugs every 20k miles.

Mind you, VWR do change their components as often as some of us change our underwear!

they are for use with only the AXX engine - which is the early version.

Why only this one I wonder... there was something about the AXX engine which made it the last of a specific type but I cant remember what it was now.

Supposedly the last of the true FSI lean burn engines...

Talking of Spark Plug I was told by a VW Dealer the recommended interval is now 60K for the BYD engine in the ED30 when I asked for the cost for the 40K service while getting Mrs PG car done today.  :surprised:

I won't be waiting that long, it really does seam VW are pushing the limits of the parts these days and I wonder if this is to help things like the cost of ownership comparisons ???

Steve, I've been advised by several tuners and others whose opinions I respect, that it's good practice to change plugs every 20k miles on a tuned engine. It's not expensive and a wise precaution to help everything run sweet.

I assume its so that lease car companies will favour VWs....

I agree, I had an occasional missfire problem which was down to a dodgy plug after 20k so I would recommend the same - for the sake of what - £40

Hi guys, the pulse plugs wouldnt cause damage as the knock sensor or i should say sensors should be in ultimate control of your timing. There seems to have been a lot written about these plugs and we have even been sent info out on them to allow us to add into ignition courses we run. Like a few of you i would like to try and see what they do as "proof is in the pudding".

You can tell if your running the wrong or right heat grade of plugs by how they are burning. Take them out and compare the non-gloss ceramic and spark tip to a spark plug colour guide.

(I have a guide on my home pc so will post it up tonight)


There are also other symptoms to too hot or cold a plug. Too cold a plug can result result in bad start-ups and can result in mis-firing.

Too hot a plug can lead to detonation (det) or pre-ignition issues. (not a good thing)

Cheapest place to order the BKR7 NGK's is here: http://www.spark-plugs.co.uk/

£6.77 inc VAT each.

Thats £27.08 a set + p&p.

I change mine every 12 months. I just order them from the website above and put them on the passenger seat in the car when it goes into VW.

Me being me, I also check to see if they've done the job!  :indifferent: :grin:

Have a look at these mate. There have been some real good things being posted about them. Also have a look on the site with the demo on how the flame front moves http://www.pulstar.com/ignitionvelocity.htm

Snake oils, and pure BS.  The spark only initiates the combustion process - the spark has jack schit to do with the speed of the flame front

There is some real interesting stuff here. With these in place you could advance the timing quite a bit which would increase BHP and Torq.

And burn holes in your pistons.  :sad:

Just stick with the OEM plugs, they are afterall good enough for the S3!
