If you still have the emmissions label / vaccum hose routing labled on the underside of your hood it'll say there. it's usually between .035 and .044

For our cars recommended is .054 .. Anywhere between .048 and .054 is good. Those plugs are probably already pre-gapped pretty close. Just make sure you check each one.
