It's for 1,1 8V, but generally the same.
Important thing: BEFORE you remove old sparkplugs, clean area around them (there is perfect place for dirt to collect). If some dust/sand fall into combustion chamber, you are in trouble (possibility of grinding piston rings, scratching cylinder walls).
Clean it with brake cleaner and compressed air (or vacuum cleaner if don't have compressor).
Example of dirt in sparkplug hole/cavity (description not in english, but it's no matter).
Dirt also increases risk of cross-threading during installation plugs again. It also ruin down washer on sparkplug (will not seat and seal properly).
Tools needed for sparks replacement. Sparks types are for 1,1 engine on this picture, but rest is the same (16 mm socket, sparks have M14x1,25 thread, gap in brand new sparks is about 0,85 mm).
Last time i've changed my sparks, they were looking like this. Gaps was about 1,30-1,40 mm, and one of the sparks collected some black sludge (probably oil burning).
Condition of engine, can be judged by how spark looks like.
Translation:
a) normal wear
b) rich mixture (injector leak) or dirty air filter
below b) another example of normal wear on spark
c) burning oil (worn piston rings or valve seals/guides)
d) bad fuel quality (too much anti-knock agent additives)
e) normal wear, but went too far (it should be replaced long time ago)
f) bad combustion process (firing too quickly, or incorrect - too low - octane fuel)
g) too much non-flammable additives/contaminations in fuel (worn fuel filter).
While you installing spark plug, you should use some anti-seize grease, but
just a little tiny drop on last few threads near washer (not around electrode).
If you are crazy and use too much (dip entire plug in can of grease) you are asking for trouble like this:
All torque specification charts are useless until they don't precise condition of the thread (new/used, perfectly clean and dry, oiled, rusted). Even brand new bolts/screws can be coated with some anti-corrosion agents acting like lube and mess up the tightening procedure.
If you installing used bolts, screws, spark plugs, whatever, threads are not in perfect condition. Using a bit of lube can help make it tight. Cleaning thread with wire brush is also good idea (clean it, but don't "grind" it, by pushing too hard, especially if you have strong made of steel wire brush, instead of brass one).
