Review on 🔧 Motion Pro 08-0175: Reliable 18mm Spark Plug Socket for Efficient Maintenance by Eddie Fowler

Does what it should! FYI, if you're changing the plug in the TRX400EX, you'll need a very long, thin-walled jack like this one. Although a bit pricey, Motion Pro #08-0175, 18mm will get the job done. If you try this with the wrong socket, the plug will not be fully inserted. I found that whoever installed the plug earlier did not fully install the plug, it was at least 1/8 inch out of the hole for an unknown amount of time as the previous owner clearly did not have a suitable outlet. Luckily the threads were still good and this socket made plug refitting easier. Expensive but excellent quality and fits the narrow and deep space in the Honda head.
