Performance radiators: all-aluminium, factory-position fitment for street and mild track use.
36mm core radiators: suited to engine bays with tighter clearances that still see daily and circuit duty.
Hyper V-Series racing radiators: KOYORAD's flagship line, with revised fin and tube pitch for more surface area in a factory-position core.
N-Flo dual pass: an internal partition routes coolant through the core for longer, for more even cooling.
Half-size race radiators: reduced-height cores for motorsport packaging, such as the Lancer Evolution VII/VIII/IX (CT9A).
HyperCore intercooler cores: universal bar-and-plate style cores in sizes from 457x127x64mm up to 711x254x102mm.
Oil and fluid coolers: universal 10, 19, 25 and 35 row oil coolers with -10AN ORB fittings, plus tube and fin crossflow fluid coolers.

KOYORAD radiators are chassis-specific, so match your chassis code before ordering: R32 Skyline GT-R/GTS-T (also covering Cefiro A31 and Laurel C33), V35 Skyline, GC8/GF8, GD/GG and GRB/GVB/VA WRX/STI, CN9A/CP9A and CZ4A Evolution, CT9A Evolution VII–IX, EG/EK/EF Civic, FK7 Civic, EP3/FK8/FL5 Civic Type R, DC2/DC5 Integra, AP1/AP2 S2000, E46/F80/F82/F83/F87 BMW and CN7 i30 Sedan N.

Gearbox and specification matter on several applications. Manual-only listings include the V35 Skyline/Infiniti G35, Accord Euro (CL9/CM2/CM3) and EF/EG Civic and CR-X. The Civic EG6/EG9 and CR-X EG2 radiator is listed for B16A manual cars, there is a non-A/C option for EG/EK Civic, and a separate radiator is listed for K-Series swapped DC2 Integra. JDM-spec and Australian-delivered versions of the same model can use different radiators, so confirm your chassis code and transmission first.

Universal coolers are chosen by dimensions and fitting size rather than chassis. Check the listed core dimensions and -10AN ORB ports against your available space and plumbing before ordering.

KOYORAD radiators are designed around factory mounting points, fan shroud bolt patterns and OEM hose locations, so most applications are a direct replacement with no cutting, drilling or bracket fabrication. Some thicker cores above 36mm may require the upper or lower hose to be trimmed slightly to clear the extra core thickness; where this applies, it is noted on the individual product page.

Plan for fresh coolant, a suitable drain container and a system bleed after fitting. Universal intercooler cores, oil coolers and fluid coolers require mounting brackets, lines and fittings to suit your application, which are not included. Installation by a professional is recommended.

Does this radiator fit my exact year and trim?
Check the vehicle sub-collections above or the fitment notes on the product page. JDM-spec and Australian-delivered versions of the same model sometimes use different radiators, so confirm your chassis code before ordering.

Do I need an aftermarket fan shroud or thermo-fan?
Usually not. KOYORAD radiators are built to factory fan shroud bolt patterns, so the original shroud and fan generally bolt back on.

What is N-Flo dual pass?
N-Flo uses an internal partition that routes coolant through the core for longer, giving more even cooling. It is available on select applications, such as the Mazda RX-7 (FC).

Can I order a KOYORAD part that isn't listed?
