Modding the Air Intake for MAF delete / IAT install
#21
Reporting back. The intake hose is 3" and the MAF inlet is 2.75" on my 95. If I go with the aluminum adapter, it will be 2.75" diameter and should pair up nicely with a cheap 3" cone filter on the other side.
I'm planning on putting in the new ECU this weekend so I'll put the IAT in the airbox for now. If it's not too ghetto, I might just leave it there.
Thanks everyone for your input.

I haven't heard of anyone else having this issue... fairly certain it's due to the lousy quality print.
Undersized, rough even with the acetone vapor bath, etc.
I'm being patient and waiting for Alec to manufacture them in CF. Silicon tape for my temporary win.

I just ran a 3/8 NPT tap through the intake plumbing then screwed the thing in, I had it for the oil pan anyway. Not optimal, but it worked and it was free. Not a lot going on with no turbo, not like it's going anywhere.
This is how it's done. Temporary permanent zipties.

I picked up a non-functioning MAF housing + gutted the sensor pocket + drilled a hole for the sensor and epoxied a 3/8NPT bung in place. Figured if it was a good location for stock it was good enough for me. It lets me use the stock crossover tube + filter housing or aftermarket.
It worked fine for 2 years of non boosted driving.

<p>well let's see: do you want to ingest an AIT sensor into your intake or not?</p><p> </p><p>it might be why i've said pre-filter like 15 times now, but by all means duct tape an ait sensor inside your IM for more accurate temp readings just before the air reaches the clyinder.</p>

I apologize for the insufficient clarity in my question. Allow me to re-word:
I assume it doesn't matter whether the sensor is secured--by screwing into a threaded insert securely mounted (e.g. glued or welded) to the intake plumbing--upstream or downstream of the air filter?

Well, mostly. I mean, if you have a cone filter like deezums or bahurd, above, I don't imagine there's really anyplace to fasten it upstream of the filter, so my question wouldn't really apply. But the stock tube to the air box or a Randall would constitute "upstream".

The one I ordered from Bell a couple years ago was an overpriced piece of crap. Be prepared to cut down the length of the threaded nipple and then re-tap it so that the element of the sensor is actually in the path of the airflow.
I mean, maybe Bell has started paying attention to these kinds of details in their production process? But I doubt it.
