Electronic Ignition Conversion Kit

Replace Points and Condenser with Zero-Maintenance Electronic Ignition

for Bosch 4-Cylinder Distributors with 1-Piece, left-pivoting points

Bosch 4-cylinder, vacuum-advance distributor with 1-piece, left-pivoting breaker points

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 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:

Replaces points and condenser with solid-state electronics

Set it and forget it - Never adjust points and timing again!

Easy to install - If you can install points, you can install the Hot-Spark electronic ignition conversion

No points to wear, burn, pit or corrode

No condenser needed

Absolutely no points float - zero - even at redline RPM and beyond!

Never worry about drifting dwell or timing again

No rubbing parts - nothing to wear out!

Fits completely under the distributor cap

Stealth modification - maintains stock appearance

Encased in high-temp thermoplastic - protected from the elements and oil, grease, dirt, water, etc.

Never bother with points or condenser again!

The best investment you'll ever make for your vehicle

Saves precious ($$$) fuel

Coil with 3.0 Ohms or more internal, primary resistance required.

Bosch Black coil is ideal for HotSpark ignition kits.

Requires a 12-volt, negative ground electrical system.

External Ballast Resistor: If the charging system voltage, measured at the coil's + terminal, is more than 13.9 volts at any RPM level, the voltage regulator likely needs replacing or a 1.4 Ohm ballast resistor should be wired between the coil's + terminal and the red HotSpark ignition wire. Too much voltage can damage the ignition module and other electronic components.

Virtually all 4-cylinder, air-cooled VW distributors have right-pivoting points. Some BMW, Porsche and Mercedes distributors have left-pivoting points; some have right-pivoting points. Please compare the points in your Bosch distributor to the photo of points below:

Determine whether your Bosch distributor has single-piece points, as early (pre-1968 or so) Bosch distributors typically have 2-piece points. If it has 2-piece points, a brass pivot pin will remain, standing up from the breaker plate, after you remove the points.

For 12-volt, negative ground electrical systems only.
