|  | | | BMW E24 Ignition Tune-Up - Page 1 | Bosch Spark Plugs  | | New spark plugs are a must for any good tune-up. Replace and check for abnormal pitting or charred plug ends. Also check each plug against each other. Any strange variations among plugs are a sure indicator that something is wrong with a particular cylinder. |

| $5.00 | | | Bosch Platinum Spark Plugs | | If you want to experience quicker starts, smoother acceleration and top fuel efficiency, Bosch Platinum is the spark plug for you. Only Bosch Platinum features a pure platinum center electrode that's heat-fused into an extended ceramic insulator to eliminate air gaps which exist in platinum alloy-tipped plugs. This superior design reaches its self-cleaning temperature faster. And with a lower ignition voltage requirement, Bosch Platinum provides reliable starting in hot and cold weather extremes and provides a more reliable spark at higher RPM's without misfires. |

Brand: Bosch | $2.55 | | | Bosch Platinum 2 Spark Plugs | | Bosch Platinum 2 plugs have double the amount of pure platinum versus Bosch Platinum in its center electrode, providing a longer performance life. Plus, two ground electrodes provide multiple spark paths, which allow the spark to find the most efficient spark path. Unlike conventional air gap spark plugs, Platinum2 plugs use surface air gap technology. The spark of a Platinum2 first travels over the surface of the insulator nose and then arcs across the air gap to a ground electrode for a longer spark, without increasing the voltage requirement. |

Replace those worn out or missing parts with one of our factory originals. Over time, old ignition wires build up resistance, reducing the amount of voltage reaching the spark plugs. Replace yours today and make sure your BMW is running at its peak. |
