How to change spark plugs in a 1997 Saab 900SE

The Saab 1997 Saab 900SE has a direct ignition system shown
in red below. The spark plugs are under the direct ignition system.
The direct ignition system takes the place of conventional spark plug
wires providing better electrical conductivity properties.
Prior to changing the spark plugs, make sure that the car has
had ample opportunity to cool down.  In order to change spark plugs,
the 4 Torx screws that hold the direct ignition system in place must
be removed.  A Torx head screw driver is included with the spare tire.


Once the 4 Torx screws have been removed, the direct ignition system
can be gently lifted up exposing the spark plugs below.  NGK
spark plugs, can be used.  The
correct spark plug and recommended gap can be obtained from
the NGK web site.   Be sure to set the gap as specified.  Changing
sparkplugs on the Saab 900SE is about as easy as it gets, as long
as you have a standard 5/8 inch spark plug socket and a 6 inch
extension for your rachet.   Remember NOT to overtighten the
new spark plugs.  They should be moderately tight.
