Commonly known performance issues with OEM Honda/Acura distributor igniters at higher power levels cause many people to convert to more reliable COP (coil on plug) style ignition systems, and the SpeedFactory Racing B-Series VTEC Coil On Plug Adapter Plate is necessary for those making the switch. Our black anodized, CNC-machined billet aluminum plate will perfectly fit atop your B-Series VTEC valve cover to adapt OEM fitment K-Series ignition coils to your engine. OEM K-Series ignition coils are always in-stock at SpeedFactory Racing for only $200/set. Note: all new adapter plates will come laser-etched with our new SFR logo!
