Why Do Optispark Distributors Fail?
If you’ve ever had to replace an Optispark distributor, you know it’s not a job you want to do twice. Unfortunately, the original design places the distributor between the engine block and the water pump—exposing it to extreme heat, poor ventilation, and contamination.
Over time, these conditions lead to common failure points, including:
-
Bearing Failure – The lubrication dries up, turning the ball bearings into metallic dust. This excessive heat then damages the Optispark module, leading to misfires or complete failure.
-
Ozone Buildup – High spark voltage inside the distributor generates ozone, which deteriorates the internal spark distribution components over time.
The Petris Optispark, built by Throwback Automotive, is designed to outlast the competition with upgraded brass components and a built-in ventilation system to prevent premature failure.
Why Choose a Petris Optispark?
Unlike many aftermarket distributors, the Petris Optispark is not a rebranded or reboxed unit. Each distributor is built from scratch in-house using high-quality components sourced from trusted suppliers. Our process has been perfected over three decades by Chris Petris, who has continuously refined the Optispark to provide unmatched reliability and performance.
When you choose a Petris Optispark, you’re getting a distributor designed by an industry expert, built with precision, and backed by a commitment to quality.
If you’re replacing your Optispark, here’s why you should choose ours:
✅ Install It Once & Forget It – Our distributors are designed for long-term reliability.
✅ Built to a Higher Standard – Cheap knockoffs use inferior materials; we don’t.
✅ Vented for Longevity – Our ventilation system helps prevent ozone damage.
✅ Fully Bench-Tested – Every unit is tested before shipping.

Do I Need to Make Any Modifications?
Each Petris Optispark distributor is fully assembled and ready for installation, with no internal modifications needed. Disassembling the unit without our authorization will void the warranty.
The only minor modification required is drilling a small hole in the air cleaner duct for proper vacuum hose placement.
