K04 Spark Plugs 20K
I hate to make another thread on the dreaded "spark plugs" but I thought I'd share what mine looked like after 20K to allow people gauge when there's should be done (early vs later).
Forgot to upload these back when they were changed. You can guess which are the old. I measured the gap on the old ones and were a TIGHT fit at 0.032". In reality, they are probably just a hair smaller. The new ones were a perfect fit at 0.028".

Which plugs did you end up using? First time I've seen an NGK branded ceramic insulator like that.

I use the PFR7S8EG gapped at 0.028". Double platinum plugs.

Nice. Any difference at 0.028 gapped?

Plugs open up over time...Not unusual. I like to replace on turbo cars at 20K, do a re-gap at 10K. This will keep your coil paks happy too..

Kind of OT but I've never had a car where I did more than change the oil. How labor intensive is it to change the plugs on these engines?
What tools are needed?

I know they probably didn't need to be but half the stuff people change don't need to be changed as early as they do. Plus, had them laying around and wanted to give them a go with my K04.

After 40k miles from new, today changed the original Bosch factory fit plugs for Denso Platimum.
Old ones looked ok and gaps were around 0.030 to 0.031". Perhaps they did not need changing, but I'd hate for them to seize up in the threaded hole as I've had on some diesel car glow plugs.. |

It's something inexpensive and can save you hassles down the road. Especially if youre tuned (in my opinion). I didn't change the fiances spark plugs in her scion till 70k. Probably just a little darker than my old ones but definitely a lot more erosion.
I'll admit, changing the coil packs may have been overkill at 20k but for $65 can't complain.

Isn't 60k miles VW's recommended service interval?
Goes to show that it may pay to mind the gap somewhere around halfway there.
