Check your ECU before you buy
R8 coils draw high current on the signal circuit, so they only work with certain ECUs. Confirmed working with: any MS3Pro, the latest MSPNP2, FlowForce MS2, SpeedyEFI PnP, and Haltech Elite.
Other Megasquirt ECUs (MS3 Basic, MS3x, early MS2, Microsquirt and others) need an additional circuit. Don't run these on an unconfirmed ECU unless you know exactly what you're doing.
Not on a confirmed ECU? Two options: the AMP Plug-and-Play ECU is confirmed and drops straight in, or the LS Coil Kit works with any standalone ECU.
This kit is built around a high-quality Bosch R8 coil, delivering enough spark to support as much boost as you dare throw at them, and designed to be an easy install into a 1990-2005 Mazda Miata. The coil fits to the valve cover via a seal we designed and produced with a custom mold.
This is a coil-on-plug setup. The coils sit directly on the spark plugs, so there are no plug wires in the kit and none are needed.
For those who insist on nothing but the classiest of installs, we've developed an optional bracket that will really tie the room together. The bracket fits non-VVT 1.8 valve covers (1994-2000) only. It does not fit a 1.6 valve cover.
Fitment notes
90-93 cars also need the 1.6 patch harness.
VVT fitment: the spark plug holes are smaller on the VVT valve cover, so you may need to trim the seal to make it fit.
