Review on 🔥 Enhance Performance with NGK 5574 PK10 Spark Plugs (BPM8Y) by William Mathis

When I inspected the spark plug I noticed it doesn't have a Japan stamp so I look at the packaging and it says Made in Brazil. I have an Echo chainsaw with a top handle, I know 1 Japanese fork will outlive 4 or 5 of these. Maybe they're ok in a lawnmower and other garden equipment since they don't spin at 11,000rpm so I leave them for backups/spares. A bit disappointed but I should have known better. You can buy them at an auto parts store for less than $3 each, so you'll save about $10, but I'd rather pay a little more and get real candles made in Japan.
