Factory replacement coil pack set for 1996-00 Miatas. If you've had the dreaded P0300 "Random misfire" code on your 1999, you need a new coil pack immediately before you destroy your catalytic converter.
This is a "three wire" setup as used in 1996-00. 1994-95 cars use a four wire coil. This three wire coil can be used on 1994-95 cars fitted with a Hydra Nemesis, but it is not compatible with a stock ECU.
