i have a 97 s90, are there any kits or body mods for this car or any other volvo that will fit my car? also are the spark plugs under the black cover? that says VOLVO 24 VALVE?

Thanks. JP

 

I have a 98 S90 and never found much on body mods, but then again I didn't look that hard. If you did they might be custom.
Yes, the spark plugs are under that cover. If they have never been replaced, they might be tight don't strip them.
