More Coil-on-Plug

[Gary Ohst]

Thanks to those responding so far.  Here are a few more comments.

The 1997/98 GM LS1 V8, and maybe Nissan?, use a coil-near-plug system. 
There are individual coils at each cylinder, however, they are still
connected to conventional spark plugs by a small lenght of spark plug
wire.

True coil-on-plug has no spark plug wires at all.  The coils connect
directly to the plug.  The coils are smaller and use higher primary
voltage to make up for the fact that they have fewer windings.  The
simplest implementation would be on 4-valve/cyl head with centrally
located spark plugs.  The coils can mount directly over the plugs.  This
is what Ford appears to have done on the 32-valve 4.6 liter V8.  It
would be more difficult on the 16-valve LS1 because the plugs still exit
to the side near the exhaust manifold.

The Oldsmobile Quad 4 might be good canidate. I'll have to check out a
current model to see if they are using the new coil-on-plug hardware.
