1992-1994 OptiSpark Unit Distributor Cap Kit - OEM Number(s) (10470953)

This direct replacement 1992-1994 LT1 Corvette OptiSpark Distributor Cap Kit is now available to allow you to rebuild or repair a failing unit.  An OptiSpark Distributor fails when exposed to moisture, causing a no start condition or engine misfire. Prevent misfire and maintain the highest performance by replacing your Opti Spark every 60,000 miles. See your service manual for installation instructions.


Tech Tip: On 1992-1996 LT1 Corvettes, you must remove the water pump to service the OptiSpark Distributor. So when you service your OptiSpark Distributor, it is a good time to replace a questionable water pump. In fact, the most common cause of OptiSpark Distributor failure is a coolant leak from the pump. Whenever you remove your water pump, always replace the gasket to prevent leaks.
