sorry this sounds really stupid but im new on the mazdas, i just got an 88 rx-7 glx and i wanna put an intake filter on it, its been to cold to go messing around under the hood lately so my question is don i need to buy a mas air flow adapter oe is it just straigt threw piping, thank you for anyone who helps me with this

you take out your existing air intake, and install the aftermarket adapter provided with the new intake..

well i just wanted to throw a filter on it right now dont have much money to buy an intake right now,

Since cost is an issue, do this-- take the top of the stock airbox out of the car, drill holes in it, clean it, and reinstall. You will have a power gain equivelant to turning off the a/c. The car will retain the original filter, but with much improved flow.

the filter is most of the intake anyway, the only other part is the adapter....

just get any old filter and a plastic MAF adapter, drill holes in the adapter to fit the MAF.

That's what I did on my old 87, and I used a Subaru Legacy cone/adapter.
