dremeling out under the lid thats the best way i could think of asking. a few friends of mine (99ss and a 98z) have dremeled under their lids to get more air into the engine. is this a good idea? just wondering if its worth it before i do it and if theres a better name for this "mod" please tell me what it is so i can search lol
Called the Free Ram Air mod, or FRA.

Inside the lid sometimes people cut back the
"baffles" looking for airflow. But a lot of the problem
is in the resonator neck and the stock lid should just
be replaced. The lower airbox is cut for "FRA" but it
does not actually ram any air and along with dirt
and water, tends to let you breathe hot radiator air
while idling and this will heat soak your IAT and pull
timing (only to come back down later, once you
have done accelerating, thanks, great).

(If you push it then you might not have a problem)
I did the mod but didnt cut the radiator shroad (sp) all to pieces and I noticed a difference.
When you stop moving the radiator starts wafting
hot air upward. How long it takes to thoroughly
warm up the inlet, I guess you'd have to watch the
scanner. I know this was a major heater for my SLP
CAI.
