Mazda BP engine- Individual coil adapter plate
Mazda BP engine – Individual coil adapter plate
The factory fitted igniton system on BP series Mazda engine are known to be troublesome. This adapter plate allows for the replacement of the original ignition coils and leads and in their place fit four individual Toyota / Denso sourced coilpacks / CoP’s. This conversion works with the original ECU is is known to improve both the power and response with no downsides.
Coil type and adapter design
Other adapters on the market use coils sourced from Toyota’s 1ZZ-FE engines, due the coil length the adapter plates are made from a flimsy sheet metal. Our adapter however uses coils from either 1NZ-FE or 2NZ-FE engines (same coil), these have a longer tube and hence this adapter plate is able to be made from a nice billet machined plate. The coils are held down by neat looking button head bolts.
Also of note these 1 / 2NZ coils have the plugs / sockets sit flat which unlike the 1ZZ type that stick up on an angle. This makes for a much neater and factory looking install.
This plate will bolt to an unmodified cam cover of the 1.8L engines out of the NA and NB models of MX5. Will not suit the VVT engine. Of note the pictured engine is the VVT variant however the cam cover was been modified to make it possible to be fitted.
