Dave they're Toyota Supra coilpacks, but are wearing Camry extension boots which can be purchased from Beck-Arnley. Many people with these COP setups prefer to hide the coils in the valley of the valve cover, and cover them up with the OEM plastic covers. I decided I wanted mine to be exposed, and mounted on aluminum flatbar where they could be cooled better, and I didn't really mind the way they look either. It's just that gawdawful split loom that detracts from them, IMO.

I did some comparison fitting and testing of different coilpacks, including Honda car & motorcycle, Chrysler, Suzuki, and 4 different Toyotas and decided I liked this arrangement best. I took all the pertinent dimensions for the different coilpacks with plugs, and will be putting up the results over on Lextreme, hopefully in the next month or two.

These coilpacks are the two wire type, which require external ignitors. Coilpacks with four or more connections, typically have the ignitors built in. I preferred these as some "smart" coilpack/ignitor combinations require to give feedback to the ECU on how much dwell current to give them, however my aftermarket ECU prefers to decide this itself, so it needs a fairly "dumb" ignitor setup.
