..has a large plastic growth on it. My question is, what is this growth called and what function does it serve. For those who have no clue what I'm talking about it's the plastic tube that fits in this hole.

Sorry this thread is vague but I don't know what I'm posting about.
My brain tells me that this plastic design may somewhat disrupt airflow.



No it's not a tumor. :fawk:

 

Never understood that myself either... I just got a SRI and was done with it

 

yes it is

 

:eek4:

 

I've been told that this is to collect a small amount of moisture if it should be drawn into the intake. Some vehicles have a U-shaped tube that fits into this location that serves the same purpose and talso to muffle sound under full-throttle.

 

There's a couple reasons why I like the stock intake. One, the rubber material doesn't absorb as much heat as a SRI. Two, it has a tapered design, 3' on the filter side and around 2.5' on the throttle side. From what I understand a tapered design is pretty efficient for midrange power.

I have removed the resonator and did a DIY Icebox CAI with an E2427 K&N filter. The only thing that baffles me is this plastic thingy that hangs off the intake. I'm very pleased with this setup as I can hear more sound from the engine, not the intake.

Interesting and also makes sense. This piece is U-shaped as you have described. Thanks for your reply. Something tells me that I should somehow modify this part.

 

I'm pretty sure its some sort of sound resonator

 

Bingo.

 

Well if that's the function it serves then maybe I shouldn't remove it. Taking out the resonator in the fender is as far as I go.

I wouldn't want my stock intake sounding like it's farting. h:

 

As with the grooves and bumps on the intake arm, it acts like a muffler. I never thought about the moisture thing, but I would imagine that moisture would be going though that arm pretty quickly and would just fly past that little hole that is suppose to collect it. :dunno:
