Eh? Why are there so many replies with no real input??
Right, the spark plugs are INCREDIBLY easy to get to on an S3.
The leads are even of a length that means you can't get them mixed up and plug them in wrong.
You do need a spark plug wrench.
and 4x £3.50 NGK or Bosch plugs.
Should take you no longer than 10 minutes total.
I'll go into ELSA and make a PDF later if no-one does before this afternoon (I'm going out all day) but it really is very, very simple.
I'm not jumping down your throat, but your total wealth of input was suggesting that it's so easy all you need is a spark plug wrench - as opposed to what? a teapot? More useful input would have been:
1. remove engine cover - by removing oil cap, then quarter turning two front screw on engine cover, then lifting slightly and pulling towards the front of car to un-locate rear lugs - ensure plastic bushes dont fall out of cover and into engine bay (else cover will rattle and **** you off).
2. Undo 2 5mm allen bolts and 2 regular bolts from vacuum canister assembly, and either push out of the way, or disconnect the lot - being very careful - the heat in this area is really nasty - and the wires around here can get really brittle. Mess it up, and it'll be a headache to say the least.
3. pull off the coilpack on the plug you're changing, there are no screws on the coilpacks on your BAM engine.
4. using a 6" extension, unscrew the plug.
5. either using the hose technique, or the spark plug adapter, CAREFULLY locate the new plug on the thread.
6. Tighten to 30Nm.
7. Push coilpack back onto plug.
8. repeat for other 3 plugs.
9. replace vacuum canister and hoses.
10 replace engine cover, careful when tightening front screws (again 1 quarter turn in either direction) - make sure that they go in properly, else they'll snap - which really ****** you off.
11. replace oil cap.
12. look at your watch and think, damn, that didnt take 10 minutes.
