Verkkowhat you need to know. The role of spark plug voltage in ignition. The voltage applied to the spark plug determines the intensity and duration of the spark, which in turn affects the combustion process. Verkkoin this test, we compared two sets of denso iridium plugs (hot heat range) q16s to a set of (much colder) iq31s. The iq16s would be similar to stock heat range plugs for our na 5. 3l, while the colder iq31s are plugs we normally run on. Understanding the intricacies of this essential component empowers you to maintain your bike’s optimal performance and prevent unexpected breakdowns. Over time, spark plugs can wear out due to constant use and exposure to high temperatures, leading to decreased performance and efficiency. No petrol engine is without spark plugs: For your engine, a constant and sufficiently powerful ignition spark is essential for good cold starting, high performance, low emissions and economical fuel consumption.
