Can you take a better pic of it? It looks like it was with a camera phone, and you started to move the phone as it (finally! I'm sure) took the picture. Also, are there any other sensors that have to be mounted into it?

1990hondahf - the 3"-2.5" coupler isnt in a kit but u can get it at autozone for 1o bucks. You can get the full intake, all the parts at autozone for around 40-55 dollars with tax and everything!! enjoy bc i am

Spectre Performance!

We all used Spectre Performance modular pieces.
Spectre Performance - Official Site

I started piecing mine as soon as I got the car, since there were no options for AT Fits. I decided to experiment with different configurations.

Short ram:


Cold Air Intake with a Ram Air between driver side fog light and a radiator using those two small scoops:






I also experimented with a short ram fully insulated and ram air through front grill on each side of the "H" badge:




I settled with a plain CAI with ram air at the end. It is easier to access things around the engine bay.
Problem with shorty is obviously the hot air coming from the radiator. If you use two bare floor shop vacuum attachments (just like in the last picture) you can get cooler air under the hood at 10 mph already, instead of 40-45mph without it.
Until we get around DBW, intake mods can't yield any real improvements we are accustomed to with our other cars. ECU compensates by closing the throttle body butterfly accordingly to keep the same air flow ratio for the sake of MPG.
I used Autoenginuity software and my laptop to monitor different intake set ups.

What size breather filter are you using as I'm doing the same job but have a choice between a 9mm, 12mm and 15mm spout and don't know what I need!!

I suspect the dangling IAT Sensor is reading a cool intake air temperature? If so, it serves to advance the timing slightly and richen the intake mixture. The result would be more power under the right conditions leading to your better mpg at cruise.

Fo Sho! Not CAI though for me. I can't afford the extra $15 to extend it that far.

I got mine installed today and installed the IAT sensor as well with the grommet from the stock box. Sounds nice compared to the stock setup.

I'm sorry for this noobish question, but for the poster above who did the CAI....

How was that positioned/located, just some general pointers if I wanted to do it on my own. Thanks!

Mock up kit you can order and then get a refund for when you buy parts:
Spectre Performance - Official Site

Kit for the intake temperature sensor(sensor is almost flat cylinder in shape, so rubber gromet works just like in the OEM set up:
Spectre Performance - Official Site

Saw kit for making a hole in the tubing:
Spectre Performance - Official Site

Mounting kit I used to secure filter assemby in the fender well(attached to wiring harness grounding point with a longer bolt):
Spectre Performance - Official Site

Throttle body coupler(black, red, yellow, blue):
Spectre Performance - Official Site

Silicone coupler in blue, red, yellow, black (for ease of instal-tubes are rigid):
Spectre Performance - Official Site

Breather filter (about 10mm opening):
Spectre Performance - Official Site

Filter cone:
Spectre Performance - Official Site

Ram air duct:
Spectre Performance - Official Site
and coupler to the filter:
Spectre Performance - Official Site


For my kit I used: 3" chrome plastic pieces:
2- 90*
1- 60*
2- 4" straight tube
1- 22* or 45* (don't remember)










Top scoop feeds into the fender well and through the outer filter cone while bottom scoop feeds into the ram air duct.

This set up is moderately quieter than short ram, but still very throaty and deep at WOT.
It works for my taste!

I like your set-up. How much did eveything cost you.
