THE TIME-TESTED ORIGINAL

High-Voltage Output*

 

 

     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!

  • Zero maintenance

  • Delivers far more voltage to the spark plugs than points-based ignitions - Increased dwell angle*

  • 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.

  • 3.0 Ohm Coil is ideal for Hot Spark 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 1.7 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 corner of 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.

 



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.
