Silverline Spark Plug Gap Tool 0.5 - 2.55mm / 0.02 - 0.1" (202148)

Product Information

Angled feeler gauges are ones whose tips are bent over at a slight angle to the rest of the blade. This can be handy for accessing harder to reach gaps, where it may not be possible to slide a standard gap gauge in straight enough to get a good reading on the width of the opening. They are also known as offset feeler gauges. Feeler Gauge Sets An incorrect spark plug gap can cause misfiring, poor fuel economy, a loss of power, and it can cause the plug to wear out faster. Combustion chamber pressure (at spark discharge) — higher compression engines need a higher voltage to generate a spark. Look no further than OEMTOOLS 26 Blade Master Feeler Gauge. This one-of-a-kind spark plug gap tool is a must-have for any serious car enthusiast. While you might be able to reset the gap to its proper setting, the electrodes will wear down to the point of no return and they must be replaced.

This tool has a recess made to adjust electrodes. If you turn it over, you can see a convenient little metric gapping scale on that very reverse side. Your owner’s manual or repair manual can help you with this information, or you can search for it. You can also speak to a mechanic about what they feel would be the proper gap for the spark plugs on your vehicle. It will depend on its age and your driving habits. What happens if the spark plug gap is too big?

The attached handle on this A&E spark plug gapper makes it very comfortable to use, whether you’re using it for measuring or gapping. It would be nice if it folded up. It’s still plenty lightweight and has an attached clip for easy carrying, but it will take up more space in your toolbox than other options.

You don’t want to overspend for the tool. So, you need to consider the features of the spark plug gap tool against the price tag. If the price tag seems too expensive for the features, don’t buy it. Because there are a lot of products that offer you great value in return for the money. Additional Features It has an easy to read scale that has a die-cast type of construction. It will stand up to being dropped on the ground and stepped on, something you can’t say about feeler gauges. This gap width is critical so electrical arcing (a “spark”) can occur at the right voltage, igniting the air fuel mixture in an engine’s internal combustion chamber. Engines with high flow intake ports (like racing engines) will have lots of charge swirl and movement in the combustion chamber, making ignition harder.

Why You Should Use a Spark Plug Gap Tool

Price: Spark plug gap tools come in various price points. If you’re on a budget, look for a tool that offers the features you need at a price that fits your budget. Secondly, there’s no way to account for spark plug handling from its factory release until it gets to you. Like, if you have those wire spark plug, then use a wire style gap tool. This type will help you avoid putting pressure on the center electrode and press on the tip. This CTA gap tool is very well-built. It’s all steel, so it won’t break, and it’s not likely to be damaged by rust. The wires are strong enough that they won’t bend or chip from normal use, though they are susceptible to breaking under enough pressure. The only part we’re not a huge fan of is the gap adjuster. It’s functional but feels flimsier than the rest.
