Pertronix D175520 Flame-Thrower OEM Replacement Vacuum Advance Cast Electronic Distributor for Rover 8 Cylinder

### Editorial Review The Pertronix D175520 Flame-Thrower OEM Replacement Vacuum Advance Cast Electronic Distributor for Rover 8 Cylinder exhibits a concerning trend of quality control issues that have left customers dissatisfied. Many users have reported various setbacks with the performance and quality of the unit soon after installation. Common grievances include the distributor rotor contacting the distributor cap, poor manufacturing standards resulting in components prone to corrosion, and significant problems with the ignition setup that prevent the engine from sparking altogether. Furthermore, installation difficulties are evident. Instruction manuals are criticized for lacking clarity, particularly regarding lubrication points, which can lead to further installation challenges. Many users have also expressed frustration with the module wiring process, as it requires cutting the original harness and lacks clear markings for polarity, increasing the risk of user error. Performance claims by Pertronix seem to be overstated. While some users reported minor improvements in performance and fuel efficiency, they remarked these benefits did not live up to expectations against the significant hassle posed by the distributor's installation and reliability problems. In sum, while the Pertronix D175520 offers a potentially more affordable alternative to used distributors, the compatibility issues, installation challenges, and quality control lapses significantly overshadow any advantages it may have. As a result, customers have often opted for competing brands rather than risking further disappointment. ### Pros and Cons **
