    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 Bosch ignition system used 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!

  • Zero maintenance

  • Delivers far more voltage to the spark plugs than points-based points

  • Reliable Hall-effect technology

  • Never gets out of adjustment

  • Rock-steady reliability

  • Dwell and timing are always spot-on accurate

  • Increased gas mileage, fuel economy

  • Quick starting

  • Smooth idling

  • Cleaner emissions

  • Longer spark plug life

  • Longer engine life

  • Cleaner engine oil due to less unburned fuel

  • Longer interval between oil changes

  • 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

  • Includes everything you need, no external ignition box required.

  • Works with stock distributor and coil

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

  • Beru Germany Blue 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 13.7 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:

Bosch 1-piece and 2-piece, left-hand and right-hand points

 

 

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.

3BOS4V2 electronic ignition conversion kit for early Bosch vacuum-advance distributors with 2-piece, right-hand points

Above: the vacuum-arm linkage in the red circle will probably have to be
ground down slightly, so that the magnet sleeve doesn't rub on it.

 

 

Sorry, we don't have ignition kits to fit early Bosch/VW distributors with the large distributor cap.


If a Bosch distributor has 2-piece points, an upright brass pivot pin will remain, standing upright from the breaker plate, after the points have been removed.
For 12V negative ground electrical systems only.
