Probably the dumbest question asked... silicone tube from throttle body to intake
 

What size it it? Im looking at getting something a little longer than the stock rubber tube that connecs from the TB to the tube.

If anyone could point out what Im looking for here, I'd definitely appreciate it.

the tube from the throttle body to the start of the intake tube

If that measurement isn't in the FSM, you can find calipers that are good enough for $10 or so.

(not a recommendation, just the first examples I found)

FSM? You lost me. a google search brings up "flying spaghetti monster" lool
