See full version: How do you know which spark plug wire goes where
If you put the wire for, say, spark plug 1 onto the top of spark plug 4, spark plug 4 is now going to fire at the wrong time. If it fires when the intake valve is open, it could set fire to the fuel-and-air mixture that’s waiting in the intake manifold and the throttle body.
In short, yes, in some situations spark plugs can increase horsepower. The theory behind spark plugs increasing horsepower is that by providing more spark to the firing tip of the spark plug, it will (and does) combust more fuel. here
The short answer is Yes, when you replace the spark plugs and wires can increase your vehicle’s performance. New spark plugs help keep your engine at its peak performance and efficiency levels. Worn or dirty spark plugs require higher voltage to get a strong enough spark to start a vehicle. here

A spark plug wire is a basic but critical engine component. It carries the high voltage (30k to 50k volts) produced by the ignition coil to the spark plug. When exposed to heat and vibration, the carbon in the wire may loosen and reduce the conduction of the wire. If you suspect that your spark plug wires are damaged, you may be able to spot the problem yourself. Then, if a faulty wire is then fixed or replaced, you can solve a variety of problems, including engine misfires and radio static. [1] X Research source [links]

In the owner’s manual, you will find a spark plug wire diagram and the firing order. With the right guide, the process of connecting the wires will take barely 2 minutes. In case you don’t get the owner’s manual, then follow the steps below:
Most of the spark plug wires are numbered. They mainly come in black, but you can also get them in yellow, orange, red and blue. If the wires are not numbered, you can lay them down, and the length will guide you. If you still cannot tell which is which, check the car owner’s manual, and it will guide you on the numbering of the wires. [links]
The distributor rotor is a small part that will turn each time the vehicle’s crankshaft turns. Crank it and see in which direction the distributor rotor will turn. The rotor can either go clockwise or counterclockwise but will not move in both directions.
After completing all the procedures mentioned above, you should check each spark plug wire before starting them. Compare them with the firing order given in the manual. Then, make sure that everything you have connected is in the determined order and linked to the correct distributor terminal. here
Look for the #1 cylinder on the engine block. You can find it by checking the cylinder block numbering format from the repair manual. All the cylinders are numbered. They work differently as per your car’s model. So, connect a spark plug wire between the #1 cylinder and the distributor’s #1 terminal. more
If your manual has the firing order as 1, 2, 3, 4 and if the rotor moves clockwise, then connect the third cylinder of distributor terminal immediately to the number one terminal. Similarly, connect the second cylinder to the third terminal. Then, the fourth cylinder to the number two terminal. more
So, this is how you can put spark plug wires in the correct order. We hope this article is helpful to you. here
Here, first, you have to remember the direction in which your rotor moves. Connect all the remaining spark plug wires one by one, according to the firing order of the repair manual. The firing order is as follows: here
