Keep your ultimate driving machine cool under pressure with this replacement auxiliary expansion tank from Rein. On modern turbocharged BMWs, the secondary cooling system plays a critical role in managing intake charge air temperatures, making a solid reservoir vital for both spirited street driving and track day reliability. This unit swaps directly into place of your fatigued or weeping factory plastic tank, utilizing factory-style hose bungs to ensure a leak-free seal with your existing lines. It's an essential maintenance update to keep your cooling system sealed tight and your power delivery consistent when pushing your chassis to the limit.

Features:

  • Designed to meet precise OEM fitment standards for a quick, hassle-free installation

  • Ensures reliable fluid containment for the dedicated intake charge air cooler system

  • Retains compatibility with original equipment cooling hoses and mounting hardware

  • Provides robust resistance against continuous pressure and heat degradation
