Heat is an enemy for rotaries. The RX-8 is setup to run particularly hot. This relay kit will lower the temperature that the cooling fans turn on by over 15 degrees. The installation of this kit is very easy and instructions are included. Improvements such as idle stability, better A/C performance and more can be expected.
