Does this kit require custom hoses?
No. The kit is designed to work with factory coolant hoses and system connections for straightforward installation.
Is this purely cosmetic or does it improve performance?
While primarily a durability upgrade, the aluminum construction also improves heat resistance and longevity compared to factory plastic coolant reservoirs.
Is professional installation required?
This kit is designed as a bolt-on replacement and can be installed by experienced DIY mechanics, though professional installation is always recommended.
