Category:Old Rx7 : Engine : Ignition + Air box

Ignition: For the ignition I used a Crain HI-6 box, and high performance plugs and wires. The ignition boxes are very easy to install, and seem to make the car a little more responsive. They claim they also increase your fuel mileage.

Air box: I replaced the stock air box with a custom polished aluminum intake modeled after the M2 system. Inside the box is 2 K&N air filters, one for each turbo and two little K&N breather filters for the blow off valves. I then took some polished 3 inch aluminum pipe and connected the are box to the turbo pipe. I believe ASP make the piping kit for both turbos but the upper turbo one is very easy to do yourself.
