When comparing high performance vs. standard replacement parts, it is of extreme importance to weigh performance and durability against value and cost. Long term costs of replacing OEM items with low-priced “budget” items or after-market replacement parts can, in many cases lead to higher consumer long-term costs. It can also lead to irreversible damage to primary and connected related systems. Obviously, if a replacement part is of lower quality and of shorter durability, it will need to be replaced more often. There are costs associated with the labor to replace these parts more often, as well as time lost for actually doing the work of replacing an automotive component. There are other “hidden” costs as well associated with this practice. They may not be costs in cold, hard cash out of pocket, but they are costly, nonetheless.
A good example of this is simply shopping around for spark plug wires for my old Buick. I got in the habit of replacing the wires at least once a year, sometimes more if a problem arose. I go to the Internet and find several varieties of options online and I read the descriptions of what my choices are. They look like this:
Description: Taylor Cable 69.95
8mm Street, Ignition Wire Set, Custom Fit, SST, Blue, Tin Coated Copper Braid, Non RFI, Blue Double Spring Locking Spark Plug Boots, High Temperature Rated To 550 Degrees, Competition Looks, GROUND SHIPPING ONLY
Description: OEM 37.41
Premium Wire Set, Spark Plug Wire Set, OEM Fit And Quality 37.41
Description: Taylor Cable 29.95
8mm High Energy, Ignition Wire Set, Custom Fit, Blue, High Temperature, Oil Resistant, RFI Suppression, 100% Silicone Boot Ends, Double Spring Locks At Plugs, GROUND SHIPPING ONLY
The first thing I notice is the huge difference in price, and like any good spendthrift, I am drawn to the cheapest spark plug wires available. Ignoring the statements about temperature ratings and RFI, I immediately think to myself, without any further research, I may want to buy the bargain set of wires. But then I think I want good wires, and the OEM brand is only eight dollars more. These are the spark plug wires that came with my vehicle, so they must be what I need. I buy them online for $37.41, have them shipped to my house and install them on my vehicle.
I take my old car for a ride, to see how much better it is going to run with the new wires on it. I notice it doesn’t run any better, as a matter of fact, it now has a slight miss in the engine. So I turn off the engine, get out of the vehicle and make sure everything is connected properly. The miss isn’t there anymore when I start the vehicle back up, so I am happy. I turn the radio on to listen to some tunes on the way back to the house, and I can hear the sound of my engine “running” on the radio, like a whining sound, drowning out a portion of the music.
I get back to the house and look at the old wires I took off in favor of the new “original equipment” wires. They don’t look the same. The old ones look heavier and bigger. The next day, I start the car up and the “miss” is back, and the engine “whine” is still on the radio. Frustrated, I put the old wires back on the car and the problems go away. So I go back to my computer and look at custom and high performance plug wires for my old Buick, and here’s what I see:
Spark Plug Wires
Brand: Taylor Cable $108.95
8mm Street, Ignition Wire Set, Custom Fit, Full Metal Jacket, Black, RFI Suppression, Braided Stainless Covering To Polished Aluminum Covers Over Silicone Plug Boots, High Performance, Custom Appearance
Spark Plug Wires
Brand: Taylor Cable $25.95
8mm High Energy, Ignition Wire Set, Custom Fit, Blue, High Temperature, Oil Resistant, RFI Suppression, 100% Silicone Boot Ends, Double Spring Locks At Plugs
Spark Plug Wires

Custom Fit 300 Race, Stainless Spark Plug Terminals, Complete EMI/RFI Suppression, 600F Temperature Resistance, More Spark Energy, More Power, Spark Plug Wire Set, 8.8mm, Wires Routed Over Valve Cover, Black
This time, I do a little research to find out what I do not understand about the sales descriptions offered. Here is what I find out about the difference in spark plug wires:
OEM wires generally rely on carbon conduction and are also used in the majority of stock replacement wires. This form of ignition wire is cheap to manufacture and generally provides adequate initial suppression for both RFI (radio frequency interference) and EMI (electromagnetic interference). The conduction portion is generally made of fiberglass or kevlar over which resistance conductive latex or sometimes silicone is layered over top. This reduces spark current to provide suppression. This works well while the conductor lasts, but it has a limited life. This type of conductor quickly fails if a high-powered ignition system is used. Temperature resistance is generally in the 550 degree F range.
I also find out that EMI from OEM spark plug wires can cause incorrect signals to be sent to engine management systems and on-board electronic devices. This is why suppression is so important. It works the same way that RFI can cause unwanted signals to be heard on my radio receiver. Engine running problems like intermittent misses to a major loss in power loss can be the result. I also find out that the problem can get worse with age due to corrosion of the sensors and connectors. Also, high performance wires can protect in temperatures as high as 1000 degrees F.
I went back to my Buick and looked at the ignition system. It had not been replaced by a high-powered ignition system. I ordered the Taylor custom 8.8-mm wires with RFI suppression for $25.57.
$11.84 less than I paid for the OEM ignition wires. I installed them a few days later when they arrived and have had no problems at all. In fact, my gas mileage has increased and my responsive acceleration increased. I have had them on my Buick for two years now and they still perform as well as the day I put them on.
Replacing with high performance automotive parts are generally considered upgrades and higher costs are associated with better quality and higher performance. As this exercise taught me, this is not always the case. Higher performance means value-added in the long-term. This relates to better customer satisfaction, better performance and durability, sometimes even less expense, but always a better value and a lot less hassle.

High Performance Doesn’t Mean High Price
Thursday, March 24th, 2011Automotive Training For Do-It-Yourselfers
Friday, February 25th, 2011Automotive training used to be a more common part of our society. Shop class was a commonly offered elective in high schools nationwide, ensuring that most boys knew their way around a car’s engine bay. Additionally, cars relied more on mechanical principles, rather than computerized systems. As a result, when a car broke down, the owner was much more likely to know how to fix it themselves, or at least have a friend or a family member who could fix it for them.
The situation has changed dramatically over the years. Today’s cars are much more complex, and their owners are much less likely to have had any automotive training. As a result, dealerships and garages are repairing a higher percentage of cars than ever before, and mechanics’ rates have risen in accordance with the increased necessity of their services.
Those who dislike the situation have another option. With a little automotive training, most people can perform more of the routine maintenance on their cars, reducing the expenses associated with car maintenance and allowing them the satisfaction of a job well done.
An oil change is an example of routine maintenance that frequently costs car owners far more than they need to spend. An oil change is a fairly simple procedure in most cars, requiring only enough automotive training for the individual to know the location of the oil filter and drain plug. A basic car care class should teach car owners how to locate major components under the hood and perform simple maintenance tasks, as well as imparting valuable tips for beginning do-it-yourselfers. For example, a good introductory class should warn students to beware of screwing a bolt or screw in crooked, known as crossing the threads.
A basic tune up is another routine maintenance task that do-it-yourselfers should be able to handle with a little automotive training. A basic tune up usually consists of changing the air filter, spark plugs, plug wires, distributor cap and rotor, and positive crankcase valve (PCV). Depending on the car and the mileage recommendations on the components, a basic tune up can also include replacing the fuel filter and/or the oxygen sensor. Rubber parts, such as drive belts and radiator hoses, may also be checked and replaced during a tune up. On most cars, these parts are easily accessed and require only a basic understanding of automotive functions.
A do-it-yourselfer who has had basic automotive training can also replace his or her own brakes. Changing the brake pads on a car is typically a dirty but simple job, requiring only a basic understanding of the braking components on a car. Additionally, there are numerous routine maintenance and repair jobs that an intermediate level amateur mechanic can usually handle on his or her own, such as replacing a battery, alternator, starter, timing belt, and many other components.
Of course, a significant advantage of having automotive training is that dealerships and garages cannot take advantage of you by recommending maintenance that may not actually need to be done. A basic understanding of auto mechanics will enable you to intelligently discuss any problems with your mechanic, understand what he or she is talking about, and recognize when his or her recommendations are exaggerated or downright unnecessary.
Obviously, knowing the basics of how a car operates can be extremely beneficial, saving you money in more ways than one. Beginning automotive training classes are usually offered at your local auto tech school or community college. Whether you intend to venture a few repairs on your own, or you simply want to be able to hold your own with your mechanic, taking a car care class ensures that you will not be a victim of your own ignorance.
