What is this?, 7A-FE (99' Euro) engine Options

What is this little "box" on my intake? I can only imagine it's some sort of silencer or something.. To keep the sound from the intake down.. Then again, I'm mechanicly impaired (spelling?) and don't know crap about engines.

back to topic...

your guess is correct. It also helps reduce sudden surges of air from going into your engine.

Does the USDM 5S-FE also have this silencer on the intake? I have seen a few pictures, but haven't seen any boxes like that.

Also, what would the difference be, if I removed it? Or closed the hole that goes from my intake "tubing" and into that box..

it is called a resonator. It is primarily to reduse the intake/growel of the engine. You can take that little box off and plug it with a vitamin bottle cap. There is another one also, on the side of the air box there is a tube near the fuse box that goes into the fender. That is connected to another big sealed resonator box. That is where some people put a CAI.

If you make a custom or buy a prebuilt CAI or Short ram intake, that box goes away, so it can't be all that bad.. Or? What would a sudden surge of air into my engine cause?

what would that cause ? usually quicker throttle responce, some people say more HP (maybe .5 - 1 in reality)
