An all-terrain vehicle (ATV) or quad bike is not only useful but also a lot of fun to drive. The bikes are motorized off-highway vehicles designed to travel on four non-pneumatic tires, with a straddled-style seat by handlebars for steering control. ATV comes in two types: type I is only for the operator and type II is for an operator as well as passengers.
To keep all the fun it is important to maintain the components inside the vehicle. Spark plugs are such parts. Considered the heart of an engine, spark plugs generate a sufficient spark to start the engine. They are linked with other functions as well.
Bad spark plugs reduce your gas mileage, increase fuel consumption, trouble starting, unable to provide quick acceleration. The right spark plug keeps your ATV’s engine safe and functions properly working. Moreso, with a bad plug you lose all the fun and energy to ride the ATV. Therefore choosing the right spark plug is crucial.

How do I choose spark plugs for ATVs?
The simple way to find out what kind of spark plug you need is by checking your manufacturer’s manual. The manual instructs you on the right type of spark plugs with time, year, and even geographical locations. Also, ATV spark plugs have numbers in their name, you can choose by following that as well. Higher numbers suggest a cooler spark plug. Besides, there is some factor to consider while choosing the spark plugs for ATV:
Fit type
Not all brands make spark plugs with accurate gap measurements. The spark plug gap helps the electrical arc to create an adequate spark, fire will not generate if the gap is too long or too short. The appropriate gap for spark plugs is between 0.6-1.0 mm. Always buy spark plugs that are the optimum fit for your engine.
Temperature
Many of us think that hotter plugs are better. That assumption is wrong. Spark plugs should be hot enough to burn the fuel effectively and cold enough to prevent pre-ignition. In that case, before purchasing notice the plug numbers written on the product description to know the heat range.
Installation
Installing spark plugs in an ATV is not a big deal. Pre-gapped plugs make installation easier. However, if spark plugs have damaged wires then the electrical system becomes critical at times, and replacing spark plugs becomes a tough task. So, choosing spark plugs with the finest wire is crucial.
Budget
The last and most important factor to consider is your budget. Expensive spark plugs do not promise to offer you the best result. Therefore, we suggest you look for plugs that will meet your requirements within your budget.
