Weld in Magnesium Anode and aluminum threaded bung.
Aluminum panels that force all the air that goes through the grill to be forced through the radiator and not around it.
Springfield Dyno Radiator, MiataCage stainless steel grille cover, 16lb radiator cap and RedLine Water Wetter package.
This is the biggest, baddest radiator you can stuff in a Miata! This is really one of the must haves if you want to make power.
