Ventilated Optispark distributor to replace original equipment unventilated distributors for all LT1 engine applications.

Standard 1 year, unlimited mileage warranty.

Highlights:

• Our Optispark unit is equipped with a MITSUBISHI-GRADE OPTICAL SENSOR MODULE. Our optical sensor is built using components that are equal to or higher quality than the original equipment optical sensor found in factory-supplied distributors.
• Our Optispark distributor cap has a ventilation port cast into it with high quality brass terminals and high voltage distribution straps.
• The brass tipped rotor of each unit is secured with Loctite, assembled, and then tested for leakage. The final touch is the installation of a vacuum ventilation hose assembly with the correct check and restrictor valves to prevent distributor cap damage
• Every unit is assembled from component level using the best possible pieces available. Aptiv electrical terminals and the correct 20 gauge TXL wire are utilized for the electrical harness. High quality Gates vacuum tubing and AuVeCo vacuum fittings are used for vacuum harnesses. 
• The Petris Enterprises Optispark kit includes all the pieces and attachments necessary to make the conversion, including manifold fittings, the vacuum hose assembly, and installation instructions. You can rest assured that you will not need to make trips back and forth to the auto parts store to buy another item to finish the project.
