Replaces Points and Condenser - Never Adjust Points or Timing Again!
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 more than a century - to the Kettering system, which was
introduced in the 1910 Cadillac. Even though you can adjust breaker points for
standard 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, variable dwell angle*

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

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
4- and 6-cylinder engines: Coil with 3.0 Ohms or more internal, primary resistance required.
8-cylinder engines: Coil with 1.5 Ohms or more internal, primary resistance required.
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.

The Hot Spark ignition fits only distributors that have points and condenser, NOT those with electronic ignition installed.

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
Hot Spark 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. Hot Spark 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 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 account, less a 25% 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.
