My 1999 Miata was overheating during the track day with the 110F outside temp. I upgraded the thin and "malnourished" OEM radiator with this amazing looking aluminum radiator. I was NOT disappointed. My Miata performed so well during my last time out in Thunderhill Raceway west track. She ran with no fuss or issues whatsoever. Fitment of this radiator with the OEM fan was of no issue. Installation went smooth.
