I was looking at one of the Ford websites and it shows :
For a 1955 Ford Thunderbird , 4.8 liter / 292 cubic inch 8 cylinder engine :
( the spark plugs are gapped at .035 inch )
what is the spark plug gap on a 1997 ford thunderbird lx 3.8 engine
1997 Ford Thunderbird 4.6L SFI 8cylThe Spark Plug Gap.054 (In thousandths of an inch)
the gap spec is .054

you need to set your gap to .054

.054 inch ( according to motorcraft . com )
.054 inch ( according to motorcraft . com )
.045
The recommended spark plug, for a 1984. Thunderbird 302, V8 engine, is a champion spark plug. The spark plugs can be purchased at most auto-parts stores.
According to one of Fords websites : For a 1993 Ford Thunderbird , 3.8 liter / 232 cubic inch V6 engine : The spark plugs are gapped at ( .054 inch )
There are several different "Bosch" spark plugs that don't need to be gapped (actually gapping them will damage them) that are perfect for Ford Thunderbirds!!!
