Replaces Points and Condenser - 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 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.
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.
Bosch Black Coil is ideal for 4- and 6-cyl 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 1.4 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.

International Buyers – Please Note:
Import duties, taxes and charges are not included in the item price or shipping charges. These charges are the buyer's responsibility.
Please check with your country's customs office to determine what these additional costs will be prior to bidding/buying.
VERY IMPORTANT -- BEFORE ORDERING:
Some distributors of vehicles, boats, etc. may differ, according to whether the stock distributor is still in place or a replacement distributor has been installed. Some otherwise similar or identical engines use different distributor brands and/or different distributor part numbers. We need your distributor's brand name, distributor part number and number of engine cylinders to ensure that the electronic ignition conversion kit is correct one for your particular distributor.
