What do you think of this product, and price.
Also, there are a lot of different individual spark plug coils on Ebay.

It is over priced.
The late GM coils are fine but make sure you put a blast tube on them.
1997 to 2005 GM Corvette coils are $30 each on Ebay.
Ignition Coil 97 05 Chevrolet Corvette C1144 Uf192 $29.95 new.


I have had no problems with my 2004 RX8 coils and I run the engine
to 8500 RPM every now and then.

Any old inductive coil will work with this system including the stock
2nd  gen RX7 Mazda coils. Use the dual output coil on
the leading (lower) plugs only.

BTW I think the FET is built in to the RX8 and GM Corvette so
there is one less part to buy.

I have some Corvette coils so I'll check it out tomorrow.
