Spark Plug Changing Help
 

I just bought my 1st 944 last week. It is a 1987 944 n/a, I bought new plugs for it and I want to learn how to change them myself, they look fairly east being there right on top. My questions are... What size Plug wrench do I need ?? What should these be gapped at ? and Is this easy to do ?

The gap should be either in the manual or on a placard in the engine compartment, off hand I think it's .030". Standard size plug socket should work, I'll get the exact size if you need it. Or just take one of the new ones to the hardware store with you and fit it.

Plugs on this car are cake - you should be done in 15 minutes tops. Just don't let anything fall down the holes, since they're vertical.

Gap = 0.75mm ± 0.05mm (or as Porsche says it in all their literature , 0.7mm + 0.1mm). 0.030" is good.

If you are going to torque the plugs when you put them in I think it's 25Nm - 30Nm.

I duct-taped a piece of tube (like a stiff straw) into my shop-vac hose and sucked out the little bit of dirt around the plugs before removing them just to keep it from falling into the cylinders.

My factory toolkit (the one with the lug wrench) has a nice "wobbly" socket for plug removal, I bet yours does too.

I find that anti sieze compund is a great help I strongly suggest using some on the plugs, cheap insurance for the next change.

cheap trick......take a piece of hose, like a garden hose, and cut it a foot long, put the top of the new spark plug in the end and this will give you something to guide the plug in and get it started so you don't cross-thread it.

My spark plug socket has the rubber insert that grips the top of the plug. This and an eight inch extension will get to the plugs quite decently.

I also use long nose pliers that have the half round notches to grab and remove the connector on the plug. Twist it as you are pulling up. Don't grip too hard or you will break it.
