Hello together, I have read here often that it is better to change the timing belts every 80 000 km. Is this to do with all Alfa ́s or someone already has experience with a higher running performance. I drive a 166 2.0 l Bj.99 and have now 86 000 km on it. Should you buy the dental equipment as original part or can it be a replica? Can this also make free workshops or should you prefer Alfa?
