K04 Spark Plugs 20K

[mark986]

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.

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?

Very simple.

what exactly makes the plugs and coil packs go bad?

those old plugs are a perfect tan. probably didnt even need to be changed.

+1 Old plugs are still fine, I'd pop em back and check in 10k miles again.

Very simple.

A rachet, extension & a 5/8" plug socket.
