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 points-based 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:

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
Coil with 3.0 Ohms or more internal, primary resistance required.
Bosch Black Coil is ideal for Hot Spark 4- and 6-cyl 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.

Marine Engine Electronic Ignition Conversion Kit Applications

Our electronic ignition conversion kits are not "one-size-fits-all." Your engine could have any number of different distributors. We'll need the number of cylinders and the brand and part number of your distributor to determine which ignition kit would fit it or whether we have an ignition kit for it at all. Supplying just the make and model of vehicle or engine is usually not sufficient to determine which ignition kit will fit. Most distributor part numbers are either on a badge or stamped into the side of the distributor body, and are usually covered with dirt and grease. It's also helpful to know if the distributor has a clip-down or screw-down cap.

Please note that SAE J1171 and UL 428D are NOT distributor part numbers, but simply US Coast Guard standards that many completely different distributors meet. These numbers are of almost no use in determining which distributor you have or what ignition kit you need.

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 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.

Foreign Orders: Shipping discount available if purchasing multiple items.
