I know of no cons, I think that it may have been installed for driveability / to protect the engine when cold.
Pros:
Slightly better throttle response,
More consistent to tune to
Pointless with no thermal wax anyway
Very minor power increase (will probably not notice)
I have none on my 4-port (stock intake manifold) and it runs fine in 20 F weather.
