Standard Ignition Distributor Cap P/N:JH-230
Keep ignition voltage reaching the right cylinder with the Standard Ignition Distributor Cap JH-234, a direct-fit replacement for the 1971-1972 Mazda 1200. The cap seats over the distributor and routes high-voltage current from the ignition coil, through the rotor, out to each spark-plug-wire terminal in the engine's firing order — so worn or cracked caps are a common cause of misfires and hard starts.
