Hot-Spark 3BOS4C2 electronic ignition conversion kit for early Bosch 4-cylinder, non-vacuum-advance distributors with 2-piece, right-hand points       Breaker plate from Bosch non-vacuum-advance distributor with 2-piece points

Early, non-vacuum-advance, 4-cylinder Bosch distributor with 2-piece points.

Note upright brass pivot pin.

If a Bosch distributor has 2-piece points, an upright brass pivot pin will remain,

standing up from the breaker plate, after the points have been removed.

Also available for 6-volt, negative ground electrical systems - 3BOS4C2-6N

Also available in 6-cylinder version - 3BOS6C2 (12-volt) or 3BOS6C2-6N (6-cylinder, 6-volt, negative ground)

 

 

    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:

  

Virtually all 4-cylinder, air-cooled VW/Porsche distributors have right-pivoting points. Early Bosch distributors (generally pre-1968 or so) have 2-piece 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:

 

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.

 

Sorry, we don't have ignition kits to fit early Bosch/VW 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 45 days from date of purchase. If the ignition kit is in perfect, unused condition, we can accept it as a retuned item, within 45 days of purchase, and offer 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.
