I wanted to post this instructions, since when I wanted to make this change there was no manual, no details no information at all.
I searched the intent, forums, blogs, etc and there was no guidance whatsoever on how to change the spark plugs on a 06 -11 Civic Si.
So here it is...
1. Remove the i-Vtec logo plastic cover
You will need:
1. Standard spark plug wrench
3. ratchet extensions 15 cm for this model to be able to teach the spark plugs (they are way below, on top of the pistons)
Step 3: BEWARE!!
CAUTION, do not do this step.
By mistake i removed the injector electricity, nothing happened, but if anything gets broken or damaged you will be in trouble
The black plastic rail you see are the injector electric connector
the metal strip with a tube is the gasoline injection to the injectors (be careful not to touch that for this application)
Step 4: PTitle this Step
2. Now we see the spark plug connectors
As you can see you can barely fit you had between the connector and the metal topping, there is no way to fit a wrench over there, so up next is the trick to this! ;)
