It comes with VTEC-E which is under 2500RPMs it run on 4 intake valves (with the other 4 just bearly opening) and above 2500 rpms it runs on all 16 valve. It also featured Roller Rockers.
Nah its not leather, its vinyl. The 92's came pre wired for VTEC, i just have to run some wires for the knock sensor.
That fuel filer was used up to 94 when they switch it to the bottom entry filter.
