Should NGK plugs work ok with Autolite plug wires?? Already bought Autolite plug wires, but was looking to change plugs. Would Autolite wires be ok with NGK plugs and my mods (in sig)? The wires are 7mm. Also, which plugs, NGK Iridium, Platinum, or V Power?

Are the Autolite Plug Wires rated for the higher temps of the headers? NGK plugs should work fine with the plug wires. Just make sure they click on to the plug when you install them. As for the NGK Spark Plugs, I have used the TR55 and TR55-IX versions. The TR55's are a copper tipped plug and will last 20-25K miles. The tip will errode and the gap will widen. For instance, I gapped mine at 0.050" and at 25K miles, the gap was in excess of 0.060". I have since replaced them with TR55-IX Iridium Plugs, These were pre-gapped at 0.050" and at 22K miles, they were still 0.050". These plugs can last 100K miles+.
