Spark Plug Gap
Installing my Precision Raceworks ignition kit toady and wonder what I should gap my plugs at (97506). I haven't found any post that talks about gapping with these coils.

Stock plugs stock gap unless you have problems then go colder plugs smaller gap. You want the largest gap possible without misfires. Start at stock 0.030-0.032'' and only reduce as necessary. In theory a "stronger" coil should support a larger gap. Your mods should not warranty colder plugs and smaller gap, although everyone's car responds differently.
