I have an RX7 VAF sitting here waiting for a good home. I believe it came off an 86. The VAF is your Air Flow Meter (Volume Air Flow) If you have a stock air intake, then it sits atop your air filter box. If you have a cone filter air intake, then it's what you attached that to.

5-7hp gain at 6000rpm

$70 shipped to your door in the US.

This upgrade is for 1st gen Proteges only. As the 2nd and 3rd gens have a MAF sensor. All install and tuning info can be found on my site.
