With correct installation and regular maintenance checks on your BPMR7A plugs you can ensure peak performance from your engine every time you drive! Following manufacturer’s instructions and taking proper precautions are always recommended when working around engines or electrical devices. To set the proper gap on your BPMR7A spark plugs, you must use a feeler gauge to measure it accurately if too wide or too narrow, it could damage your engine components or reduce efficiency. The large spark also reduces fouling, meaning fewer tune-ups are necessary over time.Īdditionally, using this setting can improve fuel economy by burning cleaner and more efficiently than other configurations.
This setting allows for a larger spark size and better combustion in the cylinders, which increases overall performance. We have done the research and put in the hours to enhance the performance, durability, and ignitability of plugs for domestic and import engines.Įxplore the benefits of our most advanced products like our iridium spark plugs at BPMR7A spark plug gap is an optimal setting that helps unlock the maximum potential of an engine. Iridium Ultra® plugs feature a laser-welded iridium finewire center electrode for optimal fuel efficiency, acceleration, and focused ignitability for long-lasting performance.Īutolite ® has been the trusted developer of spark plugs for over 85 years. This makes it the preferred gapping tool for shop techs to use when setting customers up with the right ignition products for their needs.Īutolite Iridium Ultra ® Spark Plugs are the highest performance offering from Autolite ® and provide the same precision and reliability of an engineered OE replacement plug. Wire loop gauges are not only accurate, but they minimize the chances of incidental damage to the plug when used correctly. Because of this, it became clear over the years that a more precise gapping tool like a wire loop gauge is recommended for this task. Like spark plug metallurgy, gapping gauges have been adapted for more focused performance over time.įeeler gauges or coin-style (ramp-style) gauges aren’t as well-suited for precision plugs like iridium because of the risks of damage to the iridium finewire electrode. To avoid this, the gap should only be checked with the right tool. Iridium spark plugs are designed to deliver more than 100,000 miles of reliable ignition and fuel efficiency, but improper gapping can easily damage the sensitive iridium electrodes. This is especially true for customers who run iridium plugs. Today’s spark plugs are precision-built products, so even the smallest adjustments will change their performance. The Right Tool to Gap Iridium Spark Plugs In either case, engine combustibility will be incorrect. If it’s too big, the coil will need too much voltage to fire.
If the gap is too small, the flame kernel will not be able to properly expand.
When replacing your customers’ spark plugs, you can help them understand that because gap distances are measured down to the tenth of a millimeter, or four one-thousandths of an inch, it’s crucial to be extra careful when checking or setting the gap in each plug. In a sense, spark plugs are an engine’s heartbeat, critical to optimal engine performance-if they’re gapped properly when they’re installed.Īs you’re aware-but your customers might not be-properly gapped plugs allow the engine to literally fire on all cylinders, while the wrong gap will not create the proper ignition and engine performance, regardless of vehicle.
