Koyo Radiator V & R Series

These are all Aluminum with Mirror Finish. Radiators gives you 20% - 30% more cooling than standard radiators. Made from aircraft quality aluminum and Heli-arc welded, cores are nocolok-brazed. This is a must have for any high performance Cars.

Fits Manual Transmission (for Automatic Transmission this will fit but Transmission cooler maybe needed).

• R and V Series Core - R-Series (53mm) and V-Series (36mm) cores provide a greater coverage for various types of engine tuning. The thickness of Core is noted by a "R" (R-series) or "V" (V-series) at the beginning of the product number.
• Nocolok Brazing - Tubes, Fins, Headers, and Brackets are brazed in a state-of-the-art Nocolok Furnace, bonding all components into an indestructible radiator.
• OE Specification Mounting - Fan mounts are situated to OE specifications allowing for both stock and performance fans to be used.
• Hand-crafted Heliarc Soldering - Each radiator is TIG-welded by hand with Heliarc soldering. Heliarc soldering is the highest in industry standard for welding aluminum connections.
• Tube and Fin Alignment - Construction under strict quality control and solid boxing result in pristine tube and fin alignment, fresh from the factory.
• Koyo Mirror Finish - All Aluminum surfaces are buffed before boxing to a confident mirror finish.

For the Miata application, the V-Series radiators will fit with OEM and larger sway bars and will not require the trimming of the fan shrouds.  Due to the thicker core of the R-Series radiators, the fans sit closer to the engine which will result in some trimming of the fan shrouds to gain clearance.  In other words, the V-Series will have less fiddle factor than the R-Series in exchange for the slightly thinner core.
