Sparkplugs do performance fade with use!
Pull the sparkplugs out and put a fresh set in ready to go. This will save you the time later down the road when you’re ready to start testing. It happens every season; somebody gets in a hurry towards the start of the season. And in the mad rush to get things going never changes out last seasons sparkplugs. Just a thought.
Check that Ignition Coil
The Ignition coil is on the same rotation cycle as the sparkplug wires. If you have a 2 year old coil or older on the racing unit. You should consider replacing it; the coil has to work very hard under the hood. And after 2 years of service it is time to swap in a fresh bullet.
Check those Sparkplug wires
Take a look at the sparkplug wires if they are 2 years old or older. You need to take them out of the racing program and put them on the street car. The wires start to age very quickly after this point. So do your racing program a favor and consider replacing them.
