Let’s take a closer look at why this specific plug might be exactly what your engine needs.
I’ve dealt with misfiring engines more times than I care to admit, often traced back to worn or inappropriate spark plugs. I needed a plug that could handle varying engine loads and temperatures without succumbing to carbon buildup. I picked up a few of these NGK plugs to test in my trusty Yamaha TW200, a bike notorious for needing the occasional spark plug swap, to hopefully get better cold start performance and low-end response.
Upon unboxing, the NGK Spark Plug appeared well-made, with a clean, sturdy design. The ceramic insulator looked pristine, and the electrode was properly gapped, demonstrating good quality control. It felt reassuringly solid in my hand, not flimsy like some cheaper alternatives I’ve encountered.
Compared to the standard Champion plug that came with the TW200 and a generic Autolite plug I had lying around, the NGK simply looked better. The Autolite felt cheap, and the Champion always seemed to foul easily. Initial impressions were positive; I was eager to see if its performance matched its appearance. This plug piqued my interest and promised reliability that I hoped would translate to fewer roadside repairs on my vintage bikes.
