Hey i want to run a pod filter, and i want it too have more airflow, and on the factory air box, its got the sensor integrated into a flap door, is there a way to separate the 2, and maybe install the sensor into a new piece of tube off the mouth of the turbo? i cant see how ide be able to seperate the sensor from the stock air box flap door deal... anyone got info

 

It's called the airflow meter, and you can unbolt it from the air box with 4 little bolts. You can buy an adapter on ebay for the square end. From there, just clamp it back in the turbo inlet duct, and clamp on your filter to the 3" round adapter.

like this:



For turbo:

 

oh ok, so peope dont actually get rid of them? does the pipe have to be the same from the mouth of the turbo to the air flow meter?

 

Oh jeez...

In order to actually get rid of the AFM (airflow meter) you have to get a standalone ECU and run it speed density, or MAP based. You can't just remove it with the stock computer, the car won't even start.

And generally, people use the stock turbo inlet duct (part that connects the turbo inlet to the AFM). It's old rubber though, so if it's cracked it won't do you any good. The turbo will suck in unmetered air and cause the engine to run bad. The inlet of the turbo is around 2", and the MAF is 3.125", so it's not the same size. You CAN get a 3" pipe welded up to replace it, but you'll need a 2" to 3" adapter for it to fit on the turbo, and a 3" to 3.125" adapter for the AFM, then the AFM adapter to fit the air filter. The stock TID is very good though, so if it's not broken, I'd just get the AFM adapter and cone filter and be done with it.

 

If we're talking NA, there's almost no reason to replace the stock intake parts. There can be a minimal gain if ducting and/or a box are used to keep the intake from sucking in hot engine bay air.

For turbo...

The stock TID is not what I'd call very good. It is a horrible design with 90° twists and turns to get it to line up with the bottom of the air box. Replacing the airbox and stock TID with a short 45° pipe significantly increased the amount of top-end boost my turbo would produce. The stock components were choking it.

Also the exact OD of the turbo inlet is 2 5/8" if an adapter is needed, and T-bolt clamps are very helpful.

 

the air flow meter is cnnected to the air box via 4 10 mm bolts, if u take the air box out of the car with the afm attached it should be obvious how it comes apart if u look at the underside of it?

 

yeah sorry for being a pain, but i just asked because i didnt wanna go messing around with afm, in my area there arent many to come by so questions first, work later. and i was just thinking of spliting the afm, but you cant regardless of the bolts being removed from the underside (plate on back of AFM with 10 od screws) it still wouldnt work, so i guess an adapter with pod filter will have to do!
