AEM's COP B-series Conversion Kit is the perfect ignition upgrade for naturally-aspirated or boosted B-Series engines that do not exceed 15 PSI of boost. It is highly affordable as it does not require the integration of a CDI module. For the weekend racer or performance enthusiast, it eliminates the dwell issues common to the factory distributor as RPM increases by providing an individual coil for each cylinder.
If your B-Series engine is stock or mildly modified, why replace factory components when you can upgrade to an affordable, premium NO MAINTENANCE coil-on-plug ignition system? It is commonly known that the factory igniter on the B-Series engine is prone to failure. Further, as distributors age timing signal quality can decrease and lead to poor engine performance.
AEM's B-Series COP Conversion Kit eliminates energy losses associated with a deteriorated cap/rotor/wire assembly and includes an igniter that has been tested under the most rigorous conditions we could conceive. "I literally tried to explode this igniter in testing," stated lead Project Engineer Jeremy Negen. "I ran it at over 10,000 RPM for over 24 hours with a dwell time that was advanced almost 50% of the way past current saturation-3.2mS versus 2.2mS-and it asked for more. It was a ridiculous condition that no igniter would ever see under even extreme operation, and it just kept going."
In testing by Honda tuning and fabrication expert Bisi Ezerioha of Bisimoto Engineering, "over 530 wheel horsepower was achieved on a turbocharged B18C GS-R engine with the AEM B-Series COP Conversion Kit with NGK Iridium spark plugs (BKR8EIX) gapped to 0.023" and no CDI module," stated Bisi. "This is the perfect coil-on-plug ignition system for moderate naturally-aspirated B-Series/Honda set ups, or boosted B-Series engines running 15 PSI or less. The harness is very straightforward, and the performance increase we saw speaks for itself."
*WHAT IF I AM RUNNING OVER 15 PSI OF BOOST?*
If your turbocharged B-Series race engine is running boost pressures higher than 15 PSI, adding AEM’s Twin-Fire Capacitive Discharge Ignition (AEM P/N 30-2821 4-Channel, sold separately) in place of the 4-Channel Coil Driver igniter will ensure adequate spark energy is delivered to the plugs regardless of boost pressure. By adding the Twin-Fire CDI, horsepower limitations become dependent on an engine’s mechanical and fueling system limitations and not spark energy delivered by the ignition system.
*ADVANCED FEATURES AND SIMPLE INSTALLATION* AEM's COP B-Series Conversion Kit is ideal for use with the AEM EMS and most aftermarket ECUs, and includes instructions for easy wire routing. It also allows for individual ignition trim tuning via a programmable EMS.
