Changing your spark plug because you think it doesn't provide enough spark inside the cylinder? While you're at it, why don't you check your spark plug wire too? If the wire's insulator is already worn out, the electricity that passes through it might arc to other metal components in your engine-which causes a weak or no spark at all. Now, if you would have to replace it, make sure that you'll get the ideal aftermarket spark plug wire for your car. And here's how to spot one:
Tip #1. Look for a spark plug wire that has a heavy-duty insulator. Basically, if the rubber outside the wire is in good condition, there's nothing wrong with your spark plug wire. You can guarantee that it would stay that way for a long time by acquiring a replacement wire that has a durable insulator. A spark plug wire with a high-strength silicone-made insulator would be a great choice since it can withstand the wear and tear that comes with constant exposure to extreme engine heat, moisture, and more.
Tip #2. Pick a spark plug wire that would fit your engine. Make sure you don't waste your time and money on a replacement wire that doesn't fit your vehicle's make and model. Check the features of the product if it's an OE replacement to guarantee two things: it can directly replace your factory-installed wires and can be installed with so much ease.
Tip #3. Check its warranty. Since you won't actually know if it would last until it's already under your hood, you have to buy a replacement wire that has a decent warranty. That way, you can quickly return it to the store where you bought it and get it replaced if it wears out prematurely. The spark plug may come with a 5-year or 50, 000 miles limited warranty or a 1-year unlimited mileage warranty depending on the brand or retailer.
Tip #4. Know how many wires you would have to replace. If you only need to change one wire, you can look for an online shop that sells a spark plug wire individually. Buying a set doesn't make sense because you wouldn't use the other wires. The only way that you would need a set is when you have to replace two or more defective spark plug wires.
