Common Spark Plug-Related Repairs

1. Spark Plug Replacement

Your spark plugs ignite the air-fuel mixture in your engine. For spark plug replacement, your new spark plugs should match the recommended type for your car and are typically replaced as a set to ensure your engine stays in sync. 

2. Ignition Coil Replacement

The ignition coil generates the power for the spark in a spark plug. Replacing a faulty coil (or coils) ensures that your spark plugs always have the energy they need to fire up.

3. How Frequently Should I Change My Car’s Spark Plugs? 

Your spark plug’s lifespan can range between 20,000 and 100,000 miles (for a long-life spark plug).

It varies depending on the:

• Spark plug metal type
• Spark plug manufacturer
• Spark plug design
• Car’s make and model

Consult your car owner’s manual to clarify when to change spark plugs.

However, if you’re looking for a general rule, most manufacturers recommend changing spark plugs every 30,000 miles.

4. What Happens If I Don’t Change My Spark Plugs?

A few bad things can happen if you don’t change your spark plugs at the recommended intervals. 

Firstly, corroded spark plugs won’t produce the required spark, so your engine must use more fuel and work harder to produce the required force. This also means you’ll end up spending more money on gas. 

Secondly, if you keep using worn spark plugs, the build-up on spark plugs can lead to an engine misfire which can put unnecessary stress on the cylinder walls. This can even cause dangerous pressure levels to build up and lead to engine failure.

5. Should All Spark Plugs Be Replaced At Once?

Most mechanics recommend changing your spark plugs as a set. 

Here’s why:

• Your spark plugs need to be on similar performance levels for optimal combustion. 
• If one of your plugs was performing well while others were old and rusty, it would put the engine out of sync. 
• Changing single plugs messes with their rotation interval. You’d have to inspect your spark plugs twice as much if each of them were on separate replacement intervals. 
• Your spark plugs should have the same electrical resistance throughout. If one performs slightly better, the engine loses its balance. It puts more pressure on your otherwise consistent combustion system and leads to excess wear and tear. 

Replacing all worn spark plugs is a standard maintenance practice, and it’s best to stick to it. You’ll be saving more time and effort in the long run!
