If the plugs are out already, why wouldn't you? For the most part, once set, they stay set. Thats not to say that triumph (or dealer) gapped them properly the first time. Check the gap.

I generally just slip my dick in between the electrodes. If it fits without too much slop they're good to go!

Okay boss. Fair enough. :loser:

Here's the straight dope: Spark plugs new out of the box are usually pretty close, but still should be checked. Some brands are worse than others, but even reliable brands can have that little electrode bent during shipping or even manufacturing.

Whenever you pull the plugs you should also re-gap them. The electric discharge of creating a spark will erode the electrode over time and gradually increase the gap. There's also no guarantee that they were properly gapped when first installed, which can also cause problems.

Always do the little maintenance things when you have the thing apart. It'll save you headache in the long run.

Thats what I thought, I have always gapped the spark plugs when I am changing them in all my cars, the reason I was asking is that when I talked to the dealer (not the service guy) he swore up and down that if I went with the stock plugs that they were pre-gapped...Actually two of the plugs are around 1 mm, which would be way out of tolerance. The old ones were also out of tolerance. I got the values written down but I don't have them with me.

Well spent late Friday and Saturday changing the plugs and I have to say....DAMN....nastiest plugs I have ever seen....is this a common issue with S3s

Standard Stuff, no tank, no air box


This plug was a bitch to get out...


The three amigos....holy freakin shiite! You can see that the 1st spark plug has a milky white color...looks like some moisture got in...

the milky white plug was lodged in Cheap's anal "crush washer." The milky white substance is a mixture of man mayo from his "yeller" S3 rally last weekend...it was his turn to bend over the seat and the other boys formed a line.
