Resonater box?

Chris_McCracken · #1 03-13-2002, 09:33 AM

I'm working on designing a new sealed [cold-air] box hi-flow intake for my truck. I will be replacing the stock airbox with a custom designed one around a hi-flow filter that will keep it clear from muck, etc... So my question is: I've noticed that the stock airbox has a "Resonater tube attached to a "resonater box". What does this do? ...and is it important? At a glance (from the name), I would guess that it is to dampen the sound level of the intake, but guesses are dangerous.

I'm not 100% sure, but I think the resonator acts like a muffler on the front end. A few years ago, I put a cold air intake on my Acura and it replaced the intake, filter and resonator. The engine sound increased dramatically.

Chris I removed mine about 8 months ago, I just used a rubber expanding freeze out plug in it's place.

Did you notice any difference in performance? It will definitely help "clean up" the engine bay a little.

If there was any improvement i could not feel it, it will take a bit more to notice an improvement when driving a 5000 pound brick through the air with Swampers

you won't notice any perf improvements. autos have had those "resonators" on since FI became widely used in the 80's. all it is for is to make the engine quieter under acceleration by absorbing the air intake groan. i might try the "clean look" like FSRBIKER did with a plug. sounds cool...
