Rubber is out, silicone is in! Upgrade your Mazdaspeed3 radiator hoses with the Mishimoto 2007-09 Mazdaspeed3 radiator hose kit to provide your Mazdaspeed3 with an advancement in both style and reliability. This kit includes the upper radiator hose, lower radiator hose, expansion tank hose, as well as six worm-gear clamps for ease of installation.

Unlike the degradation-prone rubber hoses your Mazdaspeed3 currently has, every Mishimoto silicone hose is constructed from five layers of silicone with heat-resistant embedded fibers to provide unmatched durability, heat tolerance, and pressure tolerance. Whether you are taking your Mazdaspeed3 to the local autocross or lapping at your next track day, trust Mishimoto with all your Mazdaspeed3 parts. This silicone hose kit is available in black, blue, or red and, like all our Mazdaspeed3 parts, includes the Mishimoto Lifetime Warranty.
