L13 and L15 Cylinder Head
#2
The DSI and the VTEC are not the same head.
The L13 is DSI (someone correct me if I'm wrong!!) while the L15 is a VTEC.
The DSI uses 2 spark plugs/3 valves per cylinder and the VTEC uses 1 spark plug/4 valves per cylinder.
The L13 is DSI (someone correct me if I'm wrong!!) while the L15 is a VTEC.
The DSI uses 2 spark plugs/3 valves per cylinder and the VTEC uses 1 spark plug/4 valves per cylinder.

It is supposed to be quite a bit more efficient.
You can read about it at:
