Does anyone have any info on swapping the MAF on my 99 4runner 3.4L with one from a non-turbo supra? I read about a guy doing this but he has a supercharged 4runner. I did some mods to my intake and thought it might be a good idea to swap out my MAF with a better one. Also how about those in cab electric ones?

 

Midiwall is the one that did it, i think someone bumped his thread a few days ago actually.

I know that on my 00 4runner there is no reason to switch the MAF as the on in mine is just a thing that sticks into the intake tube and get the reading. not a piece of the intake like the older style. o sure if the 99 is the old or new one though.

 

The one midiwall uses is from a 93-98 Twin turbo.

 

Is that a common/worthwhile swap for a 3.0?

 

Can a 98 3.4 MAF be converted to the newer 00 model MAF? The one on my 98 looks to be very restrictive.

 

anybody do this maf swap?

 

i put a 99 maf and intake on my 98 its only a few wires to move around

 

also does anyone know how to test one to make sure its good i think mines going bad

 

How did you know what wires to move around? I Swapped out the factory 1 piece 1998 Vane style for a 1999 replacable style with an Air Raid intake kit. The Truck started instanly maybe 1 crank, but ZERO throttle response. Went back to factory stock, open up front of stock air box w/ 6" hole and installed an Air Raid replacement filter. Truck runs great takes 4-5 cranks to fire.
