Review on ๐Ÿ”ฅ Enhance Performance with 4 New NGK IRIDIUM IX Spark Plug LTR6IX-11 # 6509 by Bobby Montoya

Revainrating 5 out of 5

My car drives better than new!

All I can say is Wow! These spark plugs breathed new life into my 2012 Ford Focus SFE. I pulled a $60,000 Motorcraft NGK and installed these little gems. After the PCM adjusted to the new spark plugs, my car accelerated so smoothly I could almost imagine driving a BMW. In general, my car drives better than new. I didn't notice a significant improvement in fuel economy, but there was a significant improvement in acceleration and engine smoothness. I would definitely buy this item again.

Pros
