OP stated desire to remove "cruise control components" which he defined as "switches, vacuum controlled actuators in the engine bay, dedicated control modules that are separate from the ecu, etc"
I agree that the SP intake allowance would allow the disconnection or removal (if bolted to the stock intake) of some components which would effectively disable the system, but removing switches, ecus, and "etc." is the concern I have.
How much weight are we talking about anyhow?
Think about the battery relocation allowance...it does not allow removal of the stock battery cables because that's modifying the harness, and there's no allowance for that in SP.
C. Relocation of the battery or batteries is permitted but not into the
passenger compartment. If the battery is relocated and the original
battery tray can be removed by simply unbolting it, the tray may
be removed, or relocated with the battery. Holes may be drilled for
mounting or passage of cables. Longer or shorter cables may be
substituted to permit relocation. The number of battery or batteries
may not be changed from stock. The area behind the rearmost seat
is not considered to be within the passenger compartment. The area
under the rearmost seat is considered to be within the passenger
Emphasis mine. Substitution equals removal in my mind.
How much weight are we talking? Lets see on a second gen RX-7, the cruise actuator is maybe 2 lbs. I'm fairly certain its controlled by the main ECU unlike the first gen which had a separate one (additional 2 lbs). The second gen also has a control stalk that is cruise control only and unplugs cleanly from the dash (Less than a quarter lb), non-cruise cars just had the hole filled with a plastic cover. The driver could easily offset that by eating a large lunch :)
