Mishimoto 2015+ Dodge Charger/Challenger 6.2/6.4L Hellcat Aluminum Expansion Tank

Dodge and Chrysler have carefully crafted the 2015-2023 6.4L Dodge Charger, Challenger, and their 6.2L Hellcat variants with imposing exteriors that live up to their namesakes. One would expect the same attention to detail under the hood and, for the most part, it all adds up - except one part: the factory expansion tank. Sticking out like a sore thumb, the dull yellow reservoir for your Mopar's coolant ends the envy brought on by the exterior. Looks aside, these plastic tanks are notorious for degrading and leaking over time. ---- We here at Mishimoto are determined to inject some style into the engine bay of your Mopar with the Mishimoto 2015-2023 Dodge Charger/Challenger and Hellcat Aluminum Expansion Tank. We have eliminated the dingy beige plastic of the stock tank and replaced it with TIG-welded aluminum, exponentially improving the expansion tank's aesthetics and durability. We also ditched the need for a sight glass or tube by incorporating a cold-fill line within the internal baffling, keeping the sleek exterior design of our tank unblemished. ---- The Mishimoto 2015-2023 Dodge Charger/Challenger 6.4L/6.2L Hellcat Expansion Tank is available in a micro-wrinkle black or natural finish. The natural finish is easy to make match any color scheme through powder coating or hydro dipping. Our expansion tank includes the Mishimoto Lifetime Warranty, which ensures you'll never again have to see the eyesore that is the stock plastic expansion tank.

Additional Information
