Spark Plugs???

[Blueisheyes86]

My Dad, My brother, and I just spent about 30 minutes searchin for the location of the spark plugs in my 1995 Q45 Infiniti. Needless to say, those spark plugs are currently hiding in an undisclosed location and I would be more than greatful if someone who knows of their location could ever so kindly inform me.

They are where they always are in a DOHC 4 valve head, right in the middle of the combustion chamber.

On the valve covers there is a black plastic piece that covers the coils, which then cover the Spark Plugs. When replacing the plugs you must remove the Air Intake hose/pipe to get to the cover. There are maybe 10 machine screws to remove with a hex/allen wrench all along the piece.

EM-7 in the service manual gives a picture of the coils under the cover. All you have to do is remove them to get to the spark plugs.

Hope that helps
