2006-2011 Honda Civic Aluminum Filler Neck by Koyo

Koyorad has taken aluminum cooling products to the next level with its all-new aluminum filler necks for various applications. These billet aluminum neck assemblies eliminate steam erosion and cracks common with plastic filler necks. Each of these necks features an integrated 1/8 PT sensor port to fit with sensors provided by most Japanese temperature gauge manufacturers. Koyorad designed these to replace the vehicle's factory filler neck to accept the more robust, deep plunger-type pressure cap such as the Koyorad SK-C13. As with most Koyorad aluminum cooling products, these filler necks are 100% direct replacements for the stock plastic filler neck assembly, making them compatible with OEM hoses and clamps.
