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!

Comparison of Left-hand (at left) and Right-hand Pivot Pin, One-piece Contact Breaker Points
Note: Some BMW 2002 cars have a distributor with left-hand pivot pin points. The 3BOS4U1 will fit only distributors with right-hand pivot pin points. If your 4-cylinder distributor has left-hand pivot pin points, order the 3BOS4U1L. Please compare the points in your car's distributor with the points in the above photo before ordering and attach a memo to your PayPal payment, indicating whether your distributor has left-hand (3BOS4U1L) or right-hand (3BOS4U1) points.
Make sure that your distributor has single-piece points, as older (pre-1968 or so) Bosch distributors typically have two-piece points. If it has two-piece points, a pivot pin will remain, standing up from the breaker plate, after you remove the points.
