For automotive enthusiasts and mechanics looking to enhance engine performance without complex modifications, Plug In Obd2 coil on plug (COP) kits offer a revolutionary solution. These systems are designed for straightforward installation and seamless integration with your vehicle’s existing electronics, delivering a significant upgrade to your ignition system. Say goodbye to complicated wiring and hello to improved engine efficiency and reliability with these innovative kits.
What is a Plug-In OBD2 Coil On Plug System?
Traditional ignition systems often rely on a distributor and single coil, which can be less efficient and prone to wear over time. Plug in OBD2 coil on plug systems revolutionize this by placing individual ignition coils directly on top of each spark plug. This direct connection eliminates the need for spark plug wires, resulting in a stronger, more consistent spark. The “plug-in” aspect of these kits is crucial; they are engineered to connect directly into your vehicle’s factory wiring harness, specifically designed to be compatible with OBD2 (On-Board Diagnostics II) systems, the standard for vehicle diagnostics in many modern cars. This compatibility ensures a hassle-free installation without the need for ECU modifications or complex rewiring.
Key Benefits of Plug-In OBD2 COP Kits
Choosing a plug in OBD2 COP kit offers numerous advantages for your vehicle:
- True Plug and Play Installation: The most significant advantage is the ease of installation. These kits are designed to be truly plug and play, meaning they require no soldering, cutting, or splicing of your factory wiring. This makes the upgrade accessible to both professional mechanics and DIY enthusiasts.
- OBD2 Compatibility: Designed to work flawlessly with your vehicle’s OBD2 system, these kits maintain all diagnostic functionalities. You won’t have to worry about triggering check engine lights or failing emissions tests. All emissions control devices continue to function as intended.
- Enhanced Engine Performance: By providing a more powerful and consistent spark, COP systems improve combustion efficiency. This can lead to noticeable gains in horsepower, torque, and throttle response. Your engine will run smoother and more powerfully across the RPM range.
- Improved Reliability and Longevity: Eliminating the distributor cap, rotor, ignition coil, and spark plug wires—components prone to wear and failure—increases the overall reliability of your ignition system. This upgrade can extend the life of your ignition components and reduce maintenance needs.
- Easy Reversion to Stock: Because these kits are plug and play, they can be easily removed and the vehicle returned to its original factory configuration if needed. This is a significant advantage for those who want to maintain the option of reverting to stock settings.
Simple Installation Process
Installing a plug in OBD2 COP kit is designed to be straightforward. While specific steps may vary slightly depending on the kit and vehicle model, the general process is as follows:
- Locate and Mount the Control Module: The control module, which manages the COP system, is typically mounted in an easily accessible location, such as on the battery tray or firewall. Many kits offer optional mounting brackets for convenience.
- Disconnect the Distributor: Unplug the existing distributor from your vehicle’s wiring harness.
- Connect the Patch Harness: The kit includes a patch harness that plugs directly into the vehicle’s engine-side and distributor-side connectors. This harness is designed for your specific OBD type (OBD1, OBD2A, or OBD2B), so it’s crucial to verify compatibility before ordering.
- Ground Wire Connection: Connect the provided ground wire to a suitable grounding point on the chassis.
- Coil Pack Connection: Plug the harness connectors into your new coil packs.
- Synchronization Procedure: Start the engine. The system typically requires a brief synchronization period, which involves the engine turning over for a couple of revolutions to confirm engine position before firing the spark plugs.

Vehicle Compatibility and Important Notes
Plug in OBD2 COP kits are often designed for specific engine families. For example, kits are available for Honda and Acura B, D, and H series engines and have been rigorously tested on various models like Civic, Integra, Prelude, and Accord. It’s essential to confirm that the kit you choose is compatible with your vehicle’s engine and OBD system (OBD1, OBD2A, or OBD2B).
Important Considerations:
- Resistor Spark Plugs: Always use resistor spark plugs with COP systems, as recommended for all coil on plug ignition setups.
- Ignition Timing Check: It’s advisable to check and adjust ignition timing with a timing light after installation, especially if you are using an aftermarket distributor or if you have bypassed a malfunctioning OEM ignition component.
- Coil Packs and Mounting Brackets: Note that most plug in OBD2 COP kits do not include coil packs or mounting brackets. These components are typically purchased separately to allow for customization and choice based on your specific needs and preferences.
Conclusion
Upgrading to a plug in OBD2 coil on plug ignition system is a smart investment for anyone seeking to improve their engine’s performance, reliability, and efficiency without the headaches of complex modifications. With their straightforward plug-and-play installation, OBD2 compatibility, and performance benefits, these kits offer a significant upgrade for your vehicle’s ignition system.
