Electronic Ignition Conversion Kit

Replace Points & Condenser with Solid-State Electronics

Set It and Forget It - Never Adjust Points or Timing Again!

    The Hot-Spark electronic ignition conversion kit replaces breaker points and condenser in the distributor to provide rock-solid reliability. With the Hot-Spark electronic ignition, dwell and timing are always spot-on accurate.

 

    No matter how strong your engine is, you won't get the most out of it without a good spark. The stock, breaker points-based ignition system uses technology that dates back almost a century - to the Kettering system, which was introduced in the 1910 Cadillac. Even though you can adjust breaker points for near-electronic ignition performance, they will burn and wear within a few thousand miles, long before the recommended replacement interval. With points, the timing will drift; power and fuel economy will suffer.

 

    The Hot-Spark electronic ignition conversion kit delivers a strong spark every time and is maintenance-free. You'll notice quicker starts, more top end power and a little gas mileage boost. It's as easy to install as points and condenser!
 

Advantages of the Hot-Spark electronic ignition conversion kit:

 

Hot-Spark 3BOS4U1 universal electronic ignition conversion kit for four-cylinder Bosch distributors

The Hot-Spark electronic ignition conversion kit is as easy to install as points and condenser!

 

 

For:

 

Bosch 6-cylinder distributors with one-piece, left-hand points (Bosch part no. 1 237 013 082) - 3BOS6U1L

 

Bosch 6-cylinder distributors with one-piece, right-hand points (Bosch part no. 1 237 013 112) - 3BOS6U1

 

All 4-cylinder VW and Porsche distributors have right-hand points. Some 6-cylinder Porsche distributors have left-hand points; some have right-hand points.

 

Left-hand and Right-hand Pivot Pin, One-piece Contact Breaker Points ( mirror image)

Comparison of Left-hand (at left) and Right-hand Pivot Pin, One-piece Contact Breaker Points

 

 

Make sure that your distributor has single-piece points, as older (pre-1968 or so) Bosch distributors typically have two-piece points. If it has two-piece points, a pivot pin will remain, standing up from the breaker plate, when you remove the points.

Volvo-Penta Marine Engines:

for four- and 6-cylinder Bosch distributors with one-piece (not two-piece), right-hand points

 

Make sure that your distributor has one -piece points, as older (pre-1968 or so) Bosch distributors typically have two-piece points. If it has two-piece points, a pivot pin will remain, standing up from the breaker plate, when you remove the points.
