{"product_id":"ignition-coil-driver-with-wiring-harness","title":"Ignition Coil Driver with Wiring Harness","description":"The Hondata Ignition Coil Pack Retrofit (CPR) Kit offers a significant upgrade over stock distributor-style ignition systems, which can degrade over time and provide inconsistent spark. By replacing the stock components with an electronic control unit capable of driving individual \"coil on plug\" igniter coils, the CPR kit ensures a stronger, more consistent spark. This is particularly beneficial for forced induction engines and high-revving naturally aspirated engines.\n\nDesigned exclusively for use with an OBD1 ECU and the Hondata S300 system, this kit allows for fine-tuning of engine performance to maximize power output. The CPR controller can also drive a CDI controller, providing an even stronger spark for higher boost pressures and enabling the use of a larger spark plug gap. The kit includes the necessary wiring harness for four Honda coil packs, the coil pack controller itself, and a flying leads harness for connecting to your distributor signal and ECU. It is typically mounted inside the vehicle, often near the ECU for a neat installation.\n\nKey features of the Hondata CPR Kit include improved driveability, reduced misfires, and the ability to accommodate a larger spark plug gap for high horsepower builds. It lessens the stress on the ignition system by providing individual coils per plug, and these individual coils are generally less prone to failure than stock integrated coil and igniter units.\n\nImportant considerations for installation include the requirement for four individual ignition coils (Hondata recommends part number 30520-PVF-A01) and the need for retention methods, such as Honda coil seals (part number 30522-RNA-A01), on engines without factory spark plug covers to prevent coils from dislodging. Furthermore, the CPR Kit mandates an ECU with a Q37 transistor already installed. Certain ECUs, such as PR4-L11, PR4-L61, PR4-A61, P06-C01, and P06-C50, may lack this necessary transistor and require either a replacement ECU or the installation of the transistor.","brand":"Hondata","offers":[{"title":"Default Title","offer_id":52688721051960,"sku":"HON-CPR","price":440.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0970\/4895\/3144\/files\/662668576.webp?v=1784893745","url":"https:\/\/store.motormia.co\/products\/ignition-coil-driver-with-wiring-harness","provider":"MOTORMIA","version":"1.0","type":"link"}
