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. 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

  • Coil with 3.0 Ohms or more internal, primary resistance required.

  • Bosch Black 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 1.4 Ohm ballast resistor should be wired between the coil's + terminal and the red Hot Spark ignition wire. Too much voltage can damage the ignition module and other electronic components.

  • Hot Spark ignition conversion kits fit only distributors that originally had points and condenser, not electronic ignition.

 

Hot-Spark 3BOS4U1 electronic ignition conversion kit for 4-cylinder Bosch distributors

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

 

Virtually all 4-cylinder, air-cooled Porsche distributors have right-pivoting points. Some 6-cylinder Porsche 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.

 

Note: Some Porsche 911 cars have a distributor with left-hand pivot pin points. The 3BOS6U1 will fit only distributors with 1-piece, right-hand pivot pin points. If your Bosch 6-cylinder distributor has  1-piece, left-pivoting points, order the 3BOS6U2L. Please compare the points in your 911's distributor with the points in the above photo before ordering and attach a memo to your PayPal payment, specifying whether your 911 distributor has left-hand (3BOS6U2L) or right-hand (3BOS6U1) 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.

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 Hot Spark ignition conversion kit won't fit your distributor.

It's important 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, 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.

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. 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, 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.

 

 

Important: So that we can ship you the correct ignition conversion kit, please attach a memo to your payment specifying the number of cylinders your engine has and the type of distributor. If for a Bosch distributor, determine whether your distributor has left-pivoting points or right-pivoting points and 1-piece or 2-piece points (see the above photo comparing left- and right-pivoting points).

 

 

Dealer Inquiries welcomed.
