Toyota Coil On Plug (COP)

Toyota Coil On Plug (COP) http://web.me.com/willm/Site/Photo_Albums/Pages/Toyota_COPs.html I have this set on my track car and need to make a new harness for my daily driver cold-side supercharged 1995 Miata. The wiring harness will likely be routed differently. More info about these pics can be found in the original blog post (click here).

I bet you are wondering what those blue decals on the valve cover are. They are heat-sensitive decals. There are a series of dots on the decals that change colors at certain temperatures. I did this for a before/after comparison of a track day with and without an phenolic spacer (ie: Hondata intake gasket). Bottom line? Not fricken’ worth it and cost me an engine due to broken intake manifold studs. http://web.me.com/willm/Site/Photo_Albums/Pages/Toyota_COPs.html#1 899c7118-4be0-4a5f-878e-93087f73c6a5 http://web.me.com/willm/Site/Photo_Albums/Pages/Toyota_COPs_files/Media/IMG_0097.jpg?derivative=thumb http://web.me.com/willm/Site/Photo_Albums/Pages/Toyota_COPs_files/Media/IMG_0097.jpg?derivative=micro

The last time I had this car on track, it was only holding a few ounces, if any. This view also inspired my radiator project and coolant re-route purchase. There would be a ton of room without the intake tubes, box, and coolant lines in the way. http://web.me.com/willm/Site/Photo_Albums/Pages/Toyota_COPs.html#4 13c6a597-5b10-4597-877e-121a8cf1ef07 http://web.me.com/willm/Site/Photo_Albums/Pages/Toyota_COPs_files/Media/IMG_0100.jpg?derivative=thumb http://web.me.com/willm/Site/Photo_Albums/Pages/Toyota_COPs_files/Media/IMG_0100.jpg?derivative=micro
