Will the Hks intake come with the places for the Mass airflow?? How much power should you get out of this???

 

Yes (if the kit is designed for the RX-7) and very little.

 

you'll get 2-5 hp.........if even that..............the stickers give you another 5 each. as Much as I like the HKS intake I cannot justify paying that much for the "kit" which isn't really a kit.......I'm sure you've seen this pic because you've researched this BEFORE POSTING here....but in case you're dumb and didn't:



all you need is the filter and a coupler....slap it on the end of the mass airflow meter......unless you have an S4, in which case you can buy the adapter found on ebay super cheap....
