1948 Chevy Spark Plugs…

Tonight’s project was removing the spark plugs and installing 8 new Champion replacements.

A few of them were very loose and just barely tightened down. The harder part was removing the plug boots which seems to be glued on! After messing with each one for a while I was able to remove them all.

I’ll have a baseline reference point to see what the plugs do under load. On the drivers side #1 was running lean, #7 was oil fouling. For historical purposes the spark gap was set to 0.045″ this was comparable to what I measured on the pulled plugs too. The brand was Champion the previous plugs were Accel brand.

Should be interesting after a hundred miles or so.
