NEW cold air intake kit ideas

[a_thomasmr23]

i was checking that out my brother did that set but i want to get some testing in first on a measured flow bench to see if you get the same output for the same a flow and that its just a bigger box

If it works out thats the plan before the MS upgrade

is the m30 a direct replacement for the m20 afm?

if the part number ends in 027 then yes, you will also need 19lb injectors.

think that was my link but that is a great site for any diy stuff crazy Aussies

i wish some one would make something that was a round to square transfer to help out the airflow into the AFM. Its basically a calibrated orifice there crap for flow

I bet with just a smooth ramp you could get 3-5% better flow out of it

the M30 AFM has a smooth ramp into the square. I've been using the M30 AFM for a few months and I'm very happy with it.

+1. Simple physics will tell you that the area above the bumper, on the leading edge of the car, should be a high(er) pressure area. It's the same concept as a splitter for your iS lip. Air hits the iS spoiler (or grills), tries to escape but runs in to the splitter (or bumper) and builds an area of pressure because of it. I'm too lazy to draw a picture, but Nando's posted link explains it well.

that's ridiculous, those people should know better. They can buy a cheap adapter off ebay for like $5 bux. I've had mine for over 4 years without a single issue, no rust, nothing. perfect fit. Don't waste your time and effort, unless of course you find a way to purchase them in bulk from a supplier on ebay...just a thought.

I tried purchasing them in bulk but shipping was like $30, which is ridiculous.

they cost $4.50 on ebay

almost any body who has hanged their own air filter should of known it was square in my opinion.

Is it wrong that I assumed most people who are purchasing this knew that the m20 AFM was square? just today 2 people have emailed me asking how to attach the cone filter to the AFM, today I added to the description that an AFM adapter is needed.on all the descriptions I have a list of parts that are included but I guess I will start including the AFM adapter even though I cant find a source for an affordable adapter.

what wind tunnel test are those show me and i'll read em

I'm not sure why you are saying this is a low pressure area there isn't any reason that i can see for it to be

to defend my claim, I bought the gauge that they used its on the way to my house so i can get some hard numbers

It is being said because that is what wind the tunnel tests results showed.

[kamotors]

just came back from shipping and this new routing is just as efficient and cleans up the area becasue its only using half the hose and only 1 coupler, so now the kit installs in about 15-20minutes (10 min if you have an m30 AFM).

[nando]

even if it's not a low pressure area, it still looks stupid on a street car.

[a_thomasmr23]

They're both low pressure areas. But this one doesn't look retarded and diminish the ability to see the road and other obstacles at night. And I didn't say it's what I wanted to do either, read up a few posts and buy a clue. ;)

is there a cone filter inside of that thing somewhere?
any pics of it w/o the heat shield cyl thinggy?
