I just called the dealer to get a price on an S5 TII AFM. $1100.00!!!!!!. OUCH. Sometimes I know that other model cars AFMs fit on each other. For instance, I have an M5 with two AFMs from the factory. BMW wants 200 each for the sensors. VW also uses one on the VR6 that costs 48.00. Same part number from Bosch. I put these in 2 years ago and not a hitch. Runs like a beast. So, has anyone cross referenced this RX7 part number with others. I am not sure if it is made by Mazda or someone like Hitchi or something. Anyone heard of switching out?

 

check the parts for sale section here, post a wtb s5 afm. you won't have to pay 1100, i promise. check ebay, junkyard, etc...

 

megasquirt is an option.

 

s5 t2 afm?
i sell u, 100 + shipping

 

Some people have done Mazda 929 AFM's I think. there is not consensus about whether they are superior or not.

 

I think the dealer was trying to rape you - w/ no vaseline

 

Sounds like it doesn't it? They are usually in line with Atkins and MazdaTrix. The parts guy on the oher end of the phone just about died too. I wonder how much wiring difference there is in the 929? It is an inline 6 I think. It should have the flow for a turbo rotary.

 

Are the NA and TII MAFs interchangable? If so, I have a S5 Na piece. Came off of a running car that recieved a Jspec swap.

 

No they are not interchangeable. They're physically the same but they're calibrated differently.

 

you can get a microtech LT10 For 1000 bucks + shipping from ebay for that price..

 

probe GT 89 or so on has a similar, and slightly rich cal'd for a stock motor, AFM.

 

Thanks guys for your input.

 

Thats why its called a stealership.
