NGK Spark Plugs BPMR7A Review

I purchased these Automotive ignition parts as a replacement for my old ones. Unfortunately they didn`t last long and failed to improve my car's performance. The only pro is that they were easy to install. However, the cons are that they didn't provide any noticeable change in my engine's performance and were a complete waste of money..

Thank you for the great support immediately after the appeal, the issue was resolved and the money was returned, the candle did not need to be sent back, otherwise there were only problems, thank you again

The spark plug is not pre-installed. Nowhere does it state that this is not the case either. The item is non-returnable and is not mentioned anywhere.
