Can you swap spark plug wires?

Removing the Old Spark Plug Wire Set Remove and replace one wire at a time, starting with the longest wire. By doing them one at a time, you will not have to worry about accidentally switching the wires. Do not jerk or tug on the wires or you may break the connection.

Can you mix and match spark plug wires?

no it won’t cause it to stumble… UNLESS you have a defective wire to begin with. I ran mismatched wires for like 2yrs because my plug boots fell apart and I had spare wires in my back seat and used them. The boost and hp range was pretty up there.

Do bigger spark plug wires make a difference?

Thicker conductors are required to carry more amps, but spark plugs are fired with very high voltage and low amperage. The thicker wires do have better insulation, usually silicone and that stands up to the heat of the engine compartment and higher voltage from modern ignition systems better than the older wires did.

Does it matter what spark plug wires you use?

Does size matter? For overall spark transfer, not necessarily. However, thicker wires, like these Moroso Super Max II 11mm wires, can provide added RFI suppression and insulation. That’s why it’s important to select a good quality set of spark plug ignition wires to deliver juice to your spark plugs.

Should I replace spark plug wires with my spark plugs?

That’s because spark plug wires aren’t actually made of wire. That’s why it pays to replace your spark plug wires before they wear out. We recommend changing them during spark plug changes (whenever your owner’s manual recommends, usually between 60,000 and 100,000 miles).

What will be the effect if the spark plugs are gapped too wide?

An engine that hesitates, or stumbles, upon acceleration is often the result of incorrectly gapped spark plugs. If spark plugs are gapped too wide, the ignition spark loses some of its strength as it crosses the spark plug gaps. This can result in engine hesitation.

Can spark plug wires increase horsepower?

New spark plug wires can increase your car’s horsepower as well as increase your car’s pick performance. It provides more spark to the firing tip of the spark plug and increases the horsepower.

What’s the difference between 7mm and 8mm spark plug wires?

8mm spark plug wires are a heavier gage wire than the 7mm type. The thicker wire has a thicker core. The core is the part of the wire that brings power to the spark plugs. A more robust core provides a lower resistance path for the power, thereby allowing more power to reach the spark plugs.

Can spark plug wires add horsepower?

Can you tell if a spark plug is bad by looking at it?

Visual Inspection. Remove and compare your old spark plugs to a new one. If the tip and/or electrode show excessive wear they should be replaced. Also, look for fuel and oil contamination.

What happens if you put the wrong spark plugs in?

But if the wires have been connected to the wrong spark plugs, then a few things could happen. At one end of the scale, if you have a V8 engine with just a couple of wires crossed, all that might happen is a misfire and loss of power. At the other end with everything messed up, just trying t…

Can spark plugs be mixed up with each other?

In between the two extremes you are going to have many variations on the same theme. If any of the above happens and you have just finished installing a new set of spark plugs, then it’s a fair bet that you have the wires mixed up. Now what you should have done is to fasten a piece of tape to each wire with the cylinder number written on it.

What to do if there is no spark in the distributor?

If you did not see a spark, remove the coil wire from the distributor cap. Attach the spark tester to the distributor end of the coil wire. Crack the engine and check for a good spark at the spark tester. If a spark is present, the problem is probably in the distributor cap, rotor or spark plug wires.

How to connect a spark plug to a distributor?

First, disconnect all the plug wires from the distributor. This should help you to not get confused. Now, identify the number one terminal on the distributor and mark it somehow, tape maybe. Then go to the number one spark plug and trace the wire back to the distributor and plug it into the number one terminal.
