What kind of spark plugs have the same reach?
“As an example, an Autolite copper 105 versus an XP Iridium 105 will have identical ceramic temperatures and the carbon burn off will be the same,” says Reeves. A spark plug’s reach is defined as the length of the threads.
Which is better a hotter spark plug or a colder spark plug?
Spark plugs with a hotter heat range will burn off carbon deposits more easily than a colder plug. “As an example, an Autolite copper 105 versus an XP Iridium 105 will have identical ceramic temperatures and the carbon burn off will be the same,” says Reeves.
Can a fine wire plug be used as a spark plug?
A wider gap increases the load on the ignition system, demanding higher voltage. Replacing this with a fine-wire plug would allow running a decent plug gap and still offer the potential for improved combustion. The copper core does transfer a significant amount of heat.
What should the heat range of a spark plug be?
A common question with performance engines is selecting a spark plug heat range. A tuner will often spec a heat range one to three steps colder than the stock heat range. This often is a result of dyno test data where the colder plug appears to work just fine.
Which is the best spark plug to use?
Spark plugs are made to take extremes in heat and pressure. But the usage period is limited, after driving many miles you need to replace them. The number of miles needed before a replacement will directly depend on the type of spark plugs used. The material iridium is considered the best material to manufacture spark plugs.
When do you know the correct spark plug?
So for a normal, street-driven engine, that 3924 recommendation is a great place to start. After a few hundred miles of operation, you could pull one or more spark plugs and evaluate their condition. As long as the center electrode is burning off the carbon deposits and appears relatively clean, then the heat range is probably correct.
Which is the best spark plug for a Chevy Silverado?
Denso 3473 spark plug is a great option firstly due to the long service material which it is made of – iridium. It shrinks the center electrode to only 0,7 mm in diameter and it make a significant effect on ignitability and longevity of a spark plug. Moreover, it fits a wide range of vehicles, including GM, Toyota, Honda, and Mitsubishi.
What kind of spark plug does a 1970 Iron use?
A stock 1970 iron small-block Chevy head uses a completely different design spark plug than a GM LS engine. Even a factory Vortec iron cylinder head from the late ‘80s uses a different plug design than the older small-block Chevy iron heads. If you don’t pay attention, it’s very easy to install the wrong spark plug.
