When & Why Replace Spark Plugs?

Warnings Signs to Check Spark Plugs:

2. Car has trouble starting
3. Radio Interference
4. The engine misfires
5. Engine hesitation
6. Vehicles consumes high fuel
7. Poor Acceleration

First of all, what are spark plugs? Spark Plugs are important to keep your car traveling up and down the road. Spark Plugs work with the motor to provide a spark to ignite the air and fuel mixture within the cylinders.  Regularly check your spark plugs, clean and change when necessary to prevent problems with your automobiles engine. If any of the warning items listed above are happening it could cause serious problems for your vehicle down the road and major headaches.

As you know, each vehicle differs in the recommendation for when to change the spark plugs. Ford recommends changing your spark plugs every 100,000 miles. You should check your car manual for your particular make and model of car.

Many of you can head to your local auto parts shop or online to purchase spark plugs at a reasonable price and make repairs as needed without help from a car dealer or auto repair shop. It is cheaper if you can do it yourself but you will need a few tools. The auto parts dealer can help you find the exact spark plugs for your vehicle and suggests essential tools to aid in the repair like a feeler gauge. If the thought of maintaining your own car frightens you, then seek a reputable mechanic or dealership in your hometown. Seriously, it was hard for my husband to get inside of our Mercury Mountaineer to remove several of the plugs. It is not always such a tight spot for many automobiles. He successfully removed and replaced all six plugs. (Est. Cost under $6.00 each) We have noticed a savings at the gas pump already. Before the idle issues arrived we had our air filter replaced during a regular oil change but the idle and shut off have not stopped. We will have to replace the Massive Air Flow Sensor(MAF) ourselves or have it repaired at a local garage. (This is an expensive procedure of nearly $400.)

Motorcraft®  & Bosch Platinum Spark Plugs
As you can see in the images above we had previously used Motorcraft Spark Plugs
and successfully exchanged them for the Bosch Platinum +4. You can find many popular brands
like Bosch, Denso, Champion and others from most auto part stores. You may find helpful
do-it-yourself videos online from sites like YouTube or other automobile maintenance sites.
