You can usually find the information about the spark plug gap on a label under the front hood. Platinum spark plugs don't work well in our cars. I don't have a good explanation for that other than hearing testamonials on the probetalk site and the other mx-3 group. I also tried platinums when the car was newer and didn't like the way the motor performed. I'm sure theres a good technical reason out there somewhere.<BR> It could just be that the new plugs are making an existing condition more noticable.<BR> My car always seems to lag until the first vris plate opens at about 3200 rpm's.

If platinum plugs aren't supposed to do well in our cars, what works the best?

platinum plugs last longer, no nitrous on them though!
