when I bought my 89 rx7 na it had it had a cone filter attached to the stock AMF im trying to put a stock air box back on. The problem is the rubber o-ring that goes around end of the AFM that fits in the air box is missing as well as the bracket that goes around the AFM that bolts it to the air box is missing Does anyone know a place that I can buy them or a way to rig it to attach it properly

 

try mazda or be creative and double up some o-rings that will allow it to seal.

worst case just buy a used intact AFM.

 

That rubber "o-ring" is actually pretty thick.
I have used sealing foam/tape (garage door/window/whatever...the stuff with sticky on one side) in the past.
With that gasket in place, you really don't need the bracket.

 

the rubber bit is N350-13-214 retail is $16.35, Mazda has 5. the bracket is N350-13-310, list $13.39, with no stock in the US, you could order, and have about a 50/50 chance of getting one.

 

I found a parts page at jim ellis mazda that shows the whole air intake assembly with part numbers. the bracket listed s350-13-310a $13.39 points to the top bracket that bolts to the bottom of the air box but the bracket that goes around the AFM and bolts to that bracket (the one I need) does not have a part number pointing to it. what do you think that means

 

Mazda probably considered the bracket as part of the AFM, so no separate #.

 

I found a used AFM with that bracket on it do you think that bracket can be taken off without damaging it

 

IIRC it just comes off.

 

thanks you guys for all the help
