With the airbox assembly attached to the unit, the vacuum reading is in the 5" range.
...
The AFM itself is responsible for most of the flow restriction - without the box in place, the pressure drop across the AFM & intake horn is 4.2"

brand doesn't matter, it's all marketing crap, you lose power with it anyway without a heatshield. so why spend 50+ dollars.

In the process of making the heatshield now.

So about that conical filter??? Which brand is the absolute best?

[u3b3rg33k]

performance air intake, LOL

Im gonna say what has been said a million times:
Your not gonna get anymore performance than the stock box no matter what you do. Your best bet is a K&N panel filter in you airbox

Oh really?

i put a k&n on and it quieted the exhaust down abit no so much drone now

[xwill112x]

I have a Aem dry flo filter its better than K&N...heat sheild, with drivers highbeam removed. works for me, and sounds good, although i cant hear it over the exhaust anymore. lol

Like all have said. The sound is nice but there needs to be an addition of an airbox. Unless you buy one pre made it is kind of a pain to make decent looking and functional box. Here is what I am putting together now. Mocked it up with cardboard and then going to cut some aluminum and then weld it together and paint with some paint that has heat shielding properties.

I don't have a 318 but this is my intake its pretty loud works well for me.

Where does one buy this?

[gearheadE30]

oh okay, but what did you do to measure the temp difference?

I'm running Megasquirt, which has an intake air temp sensor. Mine is mounted basically right in front of the throttle body.
