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, water, etc.

Never bother with points or condenser again!

The best investment you'll ever make for your vehicle

Saves precious ($$$) fuel

Stock Bosch points coil or a replacement coil that has 3.0 Ohms or more internal, primary resistance required.

The Bosch Black Coil with 3.4 Ohms primary resistance is ideal for HotSpark ignition kits.

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.
Requires a 12-volt, negative ground electrical system.

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

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.

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

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.

If your Bosch distributor part number, normally found on the side of the distributor body, is not among those listed on the relevant web page, chances are, the HotSpark ignition conversion kit won't fit your distributor.

It's imperative that we know your distributor's brand name, distributor part number and the number of cylinders of your engine. You may need to remove the distributor temporarily, so that you can read the distributor part number from the side of the distributor body. Usually, the side of your distributor will be covered with oil and dirt, so you'll need to clean it to find the distributor brand name and exact part number.

We can guarantee only that each of our ignition kits will fit a distributor with one of the distributor part numbers listed on its relevant web page. Otherwise, it likely won't fit. HotSpark ignition kits require a 12-volt, negative ground (earth) electrical system.

If you order the wrong electronic ignition conversion kit for your distributor, you'll need to return it to us, via US Postal Service mail within 30 days from date of purchase. If the ignition kit is in perfect, unused condition, we can accept it as a retuned item, within 30 days of purchase, and provide a refund to your PayPal account, less a 20% restocking fee and any international shipping fees, etc., but only if the ignition kit is in pristine, unused condition. Buyer is responsible for shipping and other costs to return the product for credit or exchange.
