Key physical/spec details from the product data include Thread Diameter: 14 mm (M14), 50cc, 70cc. Use the compatibility table and product photos together before ordering.
Do I need to match the OEM part number?
Yes. If your original part has a stamped OEM or manufacturer number, match that number first before ordering. For this spark plug, also compare the thread size, reach, heat range, electrode style, and original plug code.
What models or situations does this part not fit?
Do not order this spark plug for machines outside the listed compatibility, or for units with different OEM numbers, dimensions, mounting points, connectors, or year-specific configurations. Do not rely only on the model name or engine size.
What should I check before ordering?
Before ordering, compare your original part with the photos and check the thread size, reach, heat range, electrode style, and original plug code. Recheck listed specs such as Thread Diameter: 14 mm (M14), 50cc, 70cc. If any connector, mounting point, size, or year detail is different, confirm fitment before installation.
I rebuild old things that are doomed for scrap. These plugs perform well . I like the fact they are red too because it is different than other brands
The spark plug works as it is supposed to! I love the red color, as it makes it easy to see the difference at a glance from other spark plugs. Where people go wrong is assuming all spark plugs can fit or work the same from engine to engine. NOT SO!!! I bought these as a replacement for a 60/80cc engine when the manufacturer's spark plug, which was super cheap, failed. This spark plug outperformed the manufacturer's original and increased overall power and speed.Advice for everyone: make certain your engine is compatible with the spark plug you choose. This spark plug is for E6TC compliant engines as a Replacement spark plug. If your engine does not use an E6TC class spark plug, it will not fit or work!FYI, most E6TC plugs are very long, and standard-sized spark plug sockets will not work. You will need one that is extra long to extract should someone being a moron tightened it too much. Finger-tight plus a bit is all that is needed. No need to crank it down super tight. Doing that affects overall performance and can, in some engines, cause damage to the piston. This is especially true for overly cheap poorly designed Chinese crap low end engines.
