ok so i got me a bomz racing cone instake filter, i start taking the stuff out of my 1988 NA Gxl, and theres the metal thing with wires sticking out and a flapper inside, at the bottum of the stock sqare filter, it looks like its for controlling the airflow but i though the throttle did that, what do i do? just put stock back on? i got a 1 hour and 30 mins before i got to go. can i just put the 3inch filter on and call it good and forget about the flapper thing! ah help me plz experts~

 

o yea, and do i need to put the air filter right onto the engine at the top(although hood mite not close havent checked) or do i put it at the end of the long pipe though connects into that flapper thing. thanks

 

that flapper thing is your AFM you'll need it, you should be able to attach the adaptor to the AFM and then put the filter on there

 

yea i just found that in the manual, what about the air pump? its connected to the old filter, does it really need filtering?

 

That's the AFM - And yes, you do need it. Unless you are running a standalone ECU (Which you are not) the car won't run without it. Because you have an S4, you will need an adaptor to make the round filter attach to the square AFM.

They look like this: (Rx7store.net (among others) sells them. It'll run about $15 - $20.)



You will also have to fab up a braket to hold the AFM in place (Level). A piece of metal bolted to the adapter and then the Car usually works.


For the Air pump go to a Pep Boys or something and buy a $5 Mini Breather style filter. Any Mechanical device that intakes air should have a filter on it.

 

only if you don't want it to fail.

Buy a breather filter at any autoparts store...

 

ok the filter luckly came with that adapter, so its all set and on, all i need to do is get a filter for the air pump, and make something to hold up the AFM, it has to be absolutly level? or just stable so its dont go jogging around?

 

Oyea, THANKS!! and what would work as a make do filter for the air pump til i get to the auto store

 

It doesn't have to be absolutely level, just not on a severe angle (front to back) or on it's side.

You can use a pair of old pantyhose and a good elastic band as a make-do filter for the airpump. Just make sure it's secure enough that it doesn't get sucked in.

 

make sure you get a breather big enough too, i've been lookin all around for one but i only see small ones, you better get a measurement on that thing

 

Ok thanks a bunch guys, u know ur stuff ! :P
