i have a 79 rx7. i just got it running. it has always had bog problem when the secondaries open. also a misfire at high rpm. i worked on this for several days with no results. just to see what it sounded like i took the air filter out it. to my suprize all my running problems went away. the brand new puralator airfilter will not flow enough air for this car. has any one else run into this?

 

interesting

 

So what are you going to do? Buy a K&N filter?
