So I think the stock gap is .044 for a '97 legacy but I'm using a hybrid motor with a EJ22 block and Ej25D heads.. so since I'm changing my plugs I've had this coil pack here for the longest time and I was wondering what do I gap the plugs to?

Plug gap for a 2.2 should be .039-.043".

You can probably gap them at .080 and they'll still fire with that MSD coil.

Not that you should, but its probably doable.

The MSD coil is a higher voltage coil right? So you can certainly open the gap some. Add to that a little lower compression ratio because of the heads. I would go in the .050-.055 range and see how it does.

 

I put an MSD 6AL box on my old Ranger and gapped the plugs at .070 just to see what it would do (normal gap was .045"). The thing ran better than it ever had. Stock coil too.

 

Actually you might try doing some searching on MSDs website. They may have a chart for determining gap range based on compression ratio.

Ok so I will start off with .050 and see how things go
