Nerdy sparkplug question
Sparks plugs, has anyone tried running CR9EIX plugs over the oem IMR9D-9H? They are both iridium same size etc, the only difference i can glean from google is that the CR9s are a "high performance" spark plug, and the IMR is a specialised iridium plug for longer life, the CR9s are cheaper has anyone tried running them? Did you notice a difference?
