The days when you changed your spark plugs every couple of years has ended. Back in the day, spark plugs really did wear out that often. A couple of things are different now. First, spark plugs are made of better materials that last longer and they're designed better. The second reason that plugs used to have to be changed was that they were fouled up with carbon deposits. The deposits built up when fuel wasn't burned completely. With modern engine management controls that just doesn't happen as often.
Engine control computers precisely time when fuel is injected into the engine and when spark plugs fire. Unless something's wrong, spark plugs just don't foul like they used to.
Electricity from the battery goes into a coil that allows power to build up to anywhere from 12,000 to 45,000 volts, depending on the vehicle. The engine management computer tells the coil when to release the power to the spark plug. The electricity travels through a wire from the coil to the spark plug. At the tip of the plug, a spark jumps between two electrodes and ignites the gas in the combustion chamber.
Some engines have more than one coil. Coils wear out and need to be replaced occasionally. Also, spark plug wires can wear out and need to be replaced.
Modern engines are delivering more power and better fuel economy all the time. That's largely credited to fast engine control computers, advanced sensors, electronic ignition and improvements to the lowly spark plug.
It'll be interesting to see where future developments take us. One last thought: it's critically important to have the right kind of spark plug for your vehicle. Because engines are designed to run with different internal temperatures, spark plugs have different designs to work properly within those temperatures. Your service advisor will be able to get the right plugs for your vehicle. And he'll be able to advise you on when you should replace your spark plugs as well.

I cannot say enough good things about Cook Automotive Repair. They knew my daughter needed her car back by this morning, so the mechanics worked late last night and early this morning to get it done. They made sure it was safety tested and ready for her by 8 am. They are as honest and reliable as an auto repair place can be. I feel like they know our vehicles and are always looking out for us to make sure we’re safe and not to just make a buck. They are kind, helpful, and calming and I have never felt like they are scamming me or making unnecessary repairs.

Haven't had this kind of customer service from a company in a long time. Austin was great at listening and taking his time of explaining. And not making you feel rushed or stressed . Would and Will return for service.

I have used Cook on a number of occasions to diagnose and repair the cars we own and have always had great service. Fair honest prices, good clean work and have never tried to up sell anything that was not needed. Keep up the great work.

Called crying on Friday around noon, car just stopped while driving. Got it towed and they called me by 3 with diagnosis and price. Back working much better than before Monday at 1pm...I just have to thank them for the compassion they had with me while I was hysterical. The front desk guys were amazingly kind and understanding. I’ve had my car fixed at many places but never received customer service this great. I actually felt better knowing they were on top of things and actually felt like they cared. Thank you front the bottom of my heart.

MoreAfter they took such great care of my parents vehicles I decided to take my car there and I now won't go anywhere else for repairs. I have a decent amount of knowledge when it comes to my vehicle and I greatly appreciate how Austin talks me through what is wrong with the vehicles and gave me reasonable options for repairs. They have worked on several things on my vehicle and not once have I had to take it back due to reoccurring issues...unlike other places. I would recommend them to anyone.

I'm witnessing quite possibly the best customer service I have ever seen; some 5-star resorts included. While I've only had my vehicle's oil changed here twice, I would bring my vehicle here for diagnostics and service without any hesitation. I've heard them thoroughly explain (in laymen terms) what is going on with someone's vehicle, what needs to be done to resolve it, and an estimated time. They are extremely professional and customer conscious. When something happens to someone's car it is usually costly and annoying to deal with - they handle every personality with care.
