New original intake hoses for the Alfa Romeo 166 are no longer produced and finding new ones is almost impossible. Even good used ones are hard to find and often cost a lot. The best solution is to replace it with a silicone intake hose.
We sell the GSR intake hose for the V6 24V engines, specifically designed for the Alfa 166. It fits all 2.5, 3.0 and 3.2 V6 24V models with the original throttle body. It comes in black and red and we give a 5 YEAR warranty.
