Cons:

2. Installation complexity: Installing the pulley kit may require some mechanical expertise, as it involves removing the engine accessories and aligning the new pulleys.

3. Potential for noise: Some users have reported a slight increase in engine noise after installing the pulley kit. This is due to the heavy-duty rubber belts, which can produce more vibrations than the OEM belts.
