Honda Civic Si / Del Sol Si & Acura Integra B16 / B18 VTEC Coil-On-Plug COP Conversion Adapter Plate (K20 / K24 / S2000 Coils)

Convert your Honda B16A or B18C VTEC engine to a modern coil-on-plug (COP) ignition system with this premium billet aluminium COP adapter plate, precision CNC-machined from 6061-T6 billet aluminium for permanent durability and dimensional accuracy. The factory distributor-based ignition system on B-Series VTEC engines is a known performance limitation — internal distributor wear, ignition coil weakness, and limited spark energy at high RPM all conspire to limit ignition reliability on built and boosted B-Series builds. This adapter plate enables a clean, professional conversion to individual coil-on-plug ignition using readily available K20, K24, or S2000 ignition coils, eliminating the distributor as a failure point and dramatically improving ignition energy, spark consistency, and high-RPM performance. Mounts directly on top of the factory B-Series VTEC valve cover and adapts OE-fit K-Series ignition coils to your B-Series engine for a clean, OEM-grade coil-on-plug installation.

Features:

• COP conversion enabler – allows direct fitment of K-Series (K20 / K24) or S2000 ignition coils to B-Series VTEC engines, eliminating the distributor-based ignition limitation

• Premium 6061-T6 billet aluminium construction – aircraft-grade aluminium delivers exceptional strength, lightweight performance, and long-term durability

• CNC machined precision – manufactured to stringent tolerances with no burrs or sharp corners, ensuring perfect fitment atop the factory B-Series VTEC valve cover

• Anodized surface finish – delivers a clean metallic aesthetic with corrosion resistance for long-term engine bay durability

• Direct bolt-on installation – mounts to factory valve cover spark plug holes without modification

• Compatible with widely available K-Series and S2000 coils – uses readily available, affordable ignition coils sourced from common Honda performance applications

• Available in silver or black anodized finish to match your engine bay aesthetic
