So I wanted to pull out that evil, evil resonator of my 89 Si. I had read an article online about how people had used dryer ducting to run air up towards the intake. Interesting, but it came out looking kinda ugly in most of the pictures. Here's a wacky idea for all my low-cost mods friends.

First off, I have a short ram, not a full CAI, so I had to get air up to the intake cone.

- Remove the bumper (I hate rust)
- Get the evil, evil resonater milk jug out of there
- Dremel a 2" diameter hole under the passenger side bumper turn signal.
- I used a 2" bass port tube (available from any sound strore or eBay fairly cheap .. or my garage if you just want one)
- A bit of black silicone sealant around the lip to hold it in place
- Some old auto air vent ducting (2.25") to channel the air to the intake cone
- If it is a full CAI, same deal, minus the vent duct
- The main cosmetic advantage is that the unpainted port tube is the same color as the bumper skirt, and looks almost like it came that way

All told, abotu $1 for the tube, $3-$4 for the silicone, and ducting can be found at any Auto Zone or Home Depot for less than $5.

Ok, there's my budget mod post for the day

you have any pics? I think I get what your saying

let me see if I can figure out how to post pics..

Ok, figured it out...

Used a Dremel to make a 2" opening.

Checking the fit...

Flush mounted before the silicone and duct.

And YES .. I cleaned the poor thing before putting it back on.. Texas bugs are horrible this time of year :?

nice and clean... good job

Can you post a pic with it on the car? Looks smooth, would make nice brake duct openings.

Sure, I'll take pics tomorrow.

The bass tube does look like a very clean install, i can't believe that I didn't think of that myself.

So it just blows air onto the cone filter in the engine bay? Doesn't seem like it would be that effective to me. I would stick the stock airbox + filter back in, plumb the bumper inlet into the airbox inlet where the resonator used to go, and plug the other inlet. Bam, ram air. Just not quite as *bling* as the big cai cone filter.

Haven't noticed much difference myself. Nicer sound without the resonator, but no big performance boost. Pretty though

Forgot to take pictures today, sorry about that. I'll make sure I get them, though.

 

[rex2nr]

maybe if you ran the tube into the stock air box, might have more of a ram air effect?

The engine sucks way harder than you'll ever be able to push.
Wanna calculate how fast you have to drive for any "ram-effect" to work? :lol:

I have a normal AEM CAI in the bumper. When Matt was tuning my car last time, the datalog said I boosted 1 psi at one point!

Ok, here are some pics.

Is that a transformer logo where the H badge should be? LOL
