KS Series 25mm Core

Koyorad is proud to introduce the first direct replacement all aluminum performance radiator for the 2011 Honda CR-Z Hybrid 6MT. This brand new application features Koyorad’s all new “KS” Series radiator core to maximize cooling efficiency in Hybrid vehicles. As always, Koyo engineered this radiator with precision, therefore it directly replaces the stock OE plastic/aluminum radiator and will bolt easily to the factory equipped fan shroud for a quick and simple installation. Koyo has also integrated a 1/8 PT female accessory fitting (supplied with a threaded plug) to accept temperature sensors typically included with most aftermarket temperature gauges. This item was tested to fit on global market Honda CR-Z 6MT vehicles.

Koyorad’s superior quality, precision hand welds, reliability and uniformity are what have earned Koyorad their reputation in performance radiators worldwide. In their production, Koyorad uses Japanese made equipment and sources only the finest aluminum available. They privately own their factories and have NEVER outsourced their manufacturing. This is truly the only way that Koyorad Japan can oversee each stage of production and react quickly to market changes. From the selection of raw materials, hand assembly of tubes/fins, TIG welding, triple pressure testing, and to the final vacuum packing, Koyorad assures a superior quality performance radiator taking engine performance to the next level.

Features:

• Precise Tube and Fin Alignment: Construction under strict quality control and solid boxing result in tubes with optimal coolant flow and fins with highly efficient heat transfer.
• Nocolok Brazing: Tubes, Fins, Headers and Brackets are brazed in a state-of-the-art Nocolok furnace, bonding all components to resist damage from vibration, road debris, and the elements.
• Billet Filler Neck: Precision machined billet filler necks are incorporated on each Koyo radiator for strength, durability and better sealing.
• OE Specific Mountin: Koyo incorporates application specific mounting locations for all fan shrouds, inlet/outlet hoses and top/bottom mounting pins, ensuring quick and pain-free installs.
• Hand Crafted Heliarc Welds: Each Koyo Alloy Race Radiator is Heliarc welded individually by hand. This creates the strongest aluminum to aluminum bond to mate all components.

Fitment:

• 2011-2016 Honda CR-Z 1.5L Hybrid

Note: Automatic vehicles will require external transmission cooler.
