Mishimoto Aluminum Expansion Tank for 2015-2023 Dodge Charger/Challenger (6.4L / 6.2L) - Black (MMRT-SRT-15BK)

Fits select 2015-2023 Dodge Charger and Challenger models, including SRT Hellcat, Scat Pack, SRT 392, and Demon (6.2L / 6.4L).

The factory plastic expansion tank on modern Mopar platforms is a notorious weak point, often prone to yellowing, degrading, and eventual cracking after repeated heat cycles. The Mishimoto Aluminum Expansion Tank (MMRT-SRT-15BK) provides a durable, permanent solution. By replacing the fragile OE reservoir with 100% TIG-welded aluminum, this tank offers significantly improved resistance to temperature transitions while enhancing engine bay aesthetics.

To maintain a clean, high-performance look, Mishimoto engineered this tank with internal baffling that incorporates a cold-fill line. This clever design eliminates the need for an unsightly external sight glass or tube. The micro-wrinkle black finish provides a factory-plus appearance that stands up to the rigors of the engine compartment.

• Integrated cold-fill tab within internal baffling keeps exterior design sleek
