If it's a SPFI, unplug it. The engine will run like poo, but the PCM's limp mode works well enough to keep it running. If it's plugged in, it won't go into limp mode and it won't run.

It is SPFI.

Can't I just trick it to so it thinks things are all good? Or somehow put the sensor in a different tube?

Reason is I want the filter right ontop of my intake. The rubber boot is so soft that it closes when i hit the gas.

You cannot bypass the maf sensor, your car will not run. You could get a boot to go between the tb and maf, and then a nissan maf adapter and non oiled cone filter and install it from there.

replace the piping between the tb and MAF with something solid....like PVC (yea, laugh all you want, but it'll work).

but if the ECU doesn't know how much air is going in (via the MAF), it won't know how much fuel to use.....which will cause many problems.

Cool. The nissan MAF adapter, is it the large piece of alluminum? I just dont like the Suby MAF because if funnels the air down to a hole the size of a Twoonie. Maybe the nissam MAF would be bigger, who knows.

don't worry about it, the holes in your cylinder heads that let the air into the combustion chambers are smaller.

The car needs the MAF it came with.

By chance has the *Subaru FI* plate been taken off off you're intake boot? If so that's you're problem. That emblem helps stiffen the tube. Just get a replacement intake tube that is intact. Or press and glue back in the old emblem if you still have it.

I'm not meaning to use a nissan maf. What I'm talking about is an adapter that bolts to the stock maf, and allows use of conical type filters.
