9th Gen Honda Civic Si Koyo Radiator - V-Series

Fits: 9th Gen Honda Civic Si

Koyo high-performance radiators are designed, manufactured, and specified to original equipment (OE) specifications, and are renowned for their OE style design made especially for Honda Civic vehicles.

Koyo radiators are produced from lightweight aircraft quality aluminum and Heliarc welded for the best durability, unless otherwise noted.  They are 30% more cooling than standard Honda Civic OEM radiators and are fully polished aluminum to a mirror finish.

Great for high revving, high-performance motors, or motors that are turbocharged, supercharged, or nitrous equipped.

All Koyo radiator cores and tanks are specifically designed and built for each application.  No universal fit parts are used. This ensures proper fitment, just like your original factory equipment!

Some applications feature special N-FLO Technology. This design cools more efficiently by allowing the coolant to remain in the radiator for a longer period of time, therefore transferring more heat to the surrounding air. Koyo N-FLO Technology is available on cars that are known to have limited airflow to the radiator.

Aluminum core is manufactured with Nocolock Brazing for a strong, durable, and anti-corrosive bond. Features a thick aluminum core, unless noted otherwise. Easy to install.

Koyo Hyper V Series Radiator Features:

• Designed for applications that are limited in size and offer less than ideal air flow.
• Uses a 36mm aluminum core with a specially designed fin and tube pitch, which helps increase surface area while still allowing for excellent airflow.
