Screwed into the head.
The number of spark plugs is equal to the number of cylinders... if it is a V6 there are 6, if it is an inline 4 then there are 4

If it is the inline 6 cylinder.............6 If it is the V-8............8
In the engine ... usually on both sides or inline on the top.

4 in the inline 4 cylinder and 6 in the V6 engine.
There are not any plugs wires. The Inline six uses coil packs over top of each spark plug.
Wow, You have a 4.0l right which is an Inline 6. That would be 6 spark plugs. What ever you plan to do STOP, call your local mechanic, PLEASE!!
Attached to the engine!! If the engine is transverse mounted, some may be in front and the others closer to the firewall. If the engine is mounted inline, the plugs will be on the left and right sides of the motor.
The spark plug gap for a 1949 Dodge 230 Inline 6 cylinder engine should be set at .025 inches. New spark plugs do not need adjusting as they are preset at the factory.
