Choose the Right Spark Plug

Caution! Be sure to use the right spark plug! Although several different spark plugs may screw into the engine, using the incorrect one will result in performance problems and possible internal engine damage. Consult your owner¡¯s manual or check your old spark plug for the manufacture part number and match our model fit guide for the right one you need.

Q&A on Spark Plugs

> Q: What is the function of a spark plug?? A: A spark plug serves as a lighter to ignite the air-fuel mixture, creating the explosion which makes your engine produce power.
A:?> Q: How do I know if I need new spark plugs? An engine that hesitates, misfires, or has rough idling instead of running smoothly may be attributed to faulty spark plugs. Also, a sudden drop in fuel economy can be traced to dirty or fouled spark plugs. If the spark plugs aren¡¯t functioning properly, it can have a negative impact on your fuel consumption.
> Q: How often should spark plugs be replaced? A:?The standard life of a lawn mower spark plug is 25 hours. It doesn't matter how well you take care of your lawn mower, spark plugs wear out after about a season's use.
> Q: How do I choose the right spark plug?A: There are many factors to consider such as dimensions and heat range. The easiest way to identify the right spark plug is to search your model at our search bar or email your model to?service@hipastore.com?for recommendations.
> Q: What happens if I don't change spark plugs? A: Spark plugs will depreciate over time, so various engine issues will arise if they are not replaced. When the spark plugs do not generate an adequate spark, the combustion of the air/fuel mixture becomes incomplete, leading to loss of engine power, and in the worst-case scenario, the engine will not run.
> Q: What happens if you don¡¯t gap your spark plugs? A:?If the gap on your spark plug isn¡¯t set to the correct specification, you might get misfires or knock or see carbon build-up or excess fuel. Always check if the gap is correct.
