Just wondering how often people change their spark plugs? Any brand/type/model recommendations?

 

Im no expert but the rule i was told was once a year would be suffice

 

Newer engines in good shape 15k no reason to change them any sooner unless your just bored.

 

I go 10k miles, thats what the manual states too.

For 100 years, ignition technology has been dominated by spark plugs . Pulse plugs are a radical departure from spark plugs. Their physical dimensions are the same as spark plugs because they have to interface with the engine and ignition system just like spark plugs. But this is where the similarity ends.
Pulse plugs incorporate a pulse circuit, which stores incoming electrical energy from the ignition system and releases the stored energy in a powerful pulse of power. Instead of 50 watts of peak power typical of all spark plugs, pulse plugs deliver up to 1 million watts of peak power. So where does the pulse plug get its incredible power?
When the ignition signal is sent to a traditional spark plug, it begins to ionize the spark gap. This means the voltage builds in the gap until a spark can be formed. During this ionization phase, which lasts about 5 millionths of a second, the incoming voltage (which has nowhere to go) heats up ignition components including the spark plug. This is wasted energy. When the ignition voltage overcomes the
resistance in the spark gap, the spark is created with an initial discharge of approximately 50 watts. Once created, the spark resides between the electrodes at very low power for over a period of 30 millionths of a second.
What’s different about a PulstarŽ Pulse Plug is instead of heating ignition parts during the ionization phase, this energy is stored in the integral circuit inside the pulse plug. When the ignition power overcomes the resistance in the spark gap, the pulse circuit discharges all of its accumulated power – 1 million watts – in 2 billionths of a second!
A simple way to think about pulse plugs is they are similar to a camera flash, whereas spark plugs are more like a flashlight. A camera flash is exponentially brighter than a flashlight even though they both may use the same battery.
Tests at an independent laboratory demonstrate how Pulstar™ pulse plugs burn fuel more efficiently than spark plugs. The ignition plume of Pulstar™ grows at more than twice the speed of the spark plug. Pulstar™ generates a much larger spark than spark plugs, which reduces overall burn time and burns the fuel more completely. Once created, the spark dissipates over a period of 30 millionths of a second.
With increased cylinder pressure, the pistons are pushed down with more force, which, in turn, generates more torque in the crankshaft, more liveliness to the throttle and more power to the wheels.
Of course, if you don’t use this torque to go faster, the engine does its work with less effort resulting in better fuel economy.
Another way PulstarŽ improves efficiency is by reducing cycle-to-cycle variation. Cycle-to-cycle variation occurs in every engine to some degree and is caused by the dynamics of combustion, load, fuel quality, mixture of air to fuel and many other combustion variables. These variables can cause the spark plug to generate a weak spark and in the worst case, a misfire. This variability in ignition timing robs all spark ignited, internal combustion engines of up to 10% of their efficiency.
The powerful spark of PulstarŽ ignites fuel more precisely, which can reduce cycle-to-cycle variation by up to 50%. This is an important contribution to improving fuel economy.
