resist or not

Good afternoon ladies and gentlemen... I'm on my ******* smartphone but anyways I'm need some semi professional input

I know the 302 requires a hot plug but I'm lost when it comes to resistor or non resistor plugs...

I'm wanting to get the accel v power copper core copper electrode descent plugs and not to expensive

So basically resistor or non resistor plugs and what about the wires with the ferrite core?

Owner's manual suggest that you refer to the Vehicle Emission Control Information Decal on the engine radiator support for spark plug and gap specifications.

Or use the motorcraft equivalent to ASF-42P or ASF-32P

At the moment the spark jumps the gap it causes a high frequency burst of energy, this is known as RFI (radio frequency interference). This is why resistor spark plugs were introduces in the mid 1960's. Placing a resistor within the spark plug suppresses the RFI. Without resistor plugs in your car you can experience static on your radio as well as interference with other sensitive electronic equipment.

& check out Taylor Thunderbolt wires. High conduction & insulative / low resistance/ great quality!

My underhood sticker says ASF42C. The parts stores list SP450. The box has both numbers and the plug has ASF42C on it. I do not know what the other plug you mentioned is.
