Was bored today so I decided to take a look at my BFI and see if I could improve it a little bit more. I noticed the baffles and extra air boxes on the hoses after the TB and before the MAF. I took the hoses off to inspect and see what was up, Figured I didnt need them...almost all the aftermarket intakes are without them too, so I knew Id be safe. One was simple to cut off and the other just popped right out. I then plugged the holes with some marine plugs cost like 2 bucks each. Simple and easy.


The intake now sounds even more throaty and a little improvement on throttle response.

Sorry Its too dark to take pictures now..so here is a few pics from a stock intake



Here is the after product before I found the rubber marine plugs....you basically can use anything that will fit snug...this was a vitamin bottle cap and a K-cup filled with epoxy.
The marine plugs are much better thou.

Seems like this is only to the 400 only, not the 300..

I think there is a reason for why its there, maybe 1 is to help a little to prevent hydrolock? I would like to see how this sounds now with your BFI

My 95 300 looks just like that as well.

The Fj cruiser guys do this to their intakes also.

They are baffles for minimizing sound (mufflers in a way)

Yeah, i wondered what they're for. How would it prevent hydrolock just curious?

Ill make sure to shoot a video tomorrow on my way to my interview...I'm going to keep messing around with this..I want to try and develop a easy BFI system that anyone could install.

I did this to my intake a few weeks back only I used freeze plugs from Advance auto which was like 2 bucks and it sounds better but no hp difference that I could tell.

so if there is no hp gain what is the point is it for sound or......?

Well although used for sound I thought the baffles can be functional a little in catching anything the filter didn’t such as small bits of water or moisture in heavy rain/ floods/puddles and in a way dry out while its there instead of going to the throttle and stalling your engine or making it run rough.

This is a cool idea, I wonder how it sounds and if you get a better throttle response or gas milage since air is more free flowing thru the intake and to the throttle

But don’t you think its risky using the exposy while all that heat under the hood is being generated what happens if the expsy slips or cracks becuase of the heat? and goes straight to your throttle body? That wouldnt be so great
