RRP Billet Mazda Rx8 Expansion Tank

Description

RRP Billet Mazda Rx8 Expansion tank

Pre-Order expected dispatch 30th October 2025 –  If order is cancelled transaction processing fees will not be refunded.

The OEM Expansion Tank level sensors are known to fail resulting in the low level coolant sensor illuminating.  The only way to get a fully functional warning system back is to replace the entire expansion tank only for this to happen again sometime in the future!

RRP have looked to replace the unsightly plastic OEM Expansion Tank with a two piece Aluminum billet system anodised in black for an aesthetic OEM+ appearance.

Unlike other aftermarket Expansion Tanks the RRP system retains all the OEM baffles, the baffles have an important function in fluid management and should be retained. Furthermore, the RRP tank retains a level sensor which is replaceable should it ever fail and therefore full OEM functionality.

Hose connections are in the same location and quantity as OEM meaning no modifications need to be made in fitting this system.

Benefits of the RRP System: 

• Replaceable Level sensor;
• Integral Sight glass for physical inspection;
• Completely serviceable item, can be disassembled and reassembled using a new O-ring;
• Sleek AN fittings for hose connections;
• OEM style baffles retained;
• OEM+ appearance.
