That depends entirely on what vehicle you're buying them for and where you're buying them.

Where are the spark plugs on a 1.1 Peugeot 106?
the spark plugs on a 106 should be in the top of the engine on earlyer models you should see 4 leads conected to them. a later model may not have ignition leads but a sort of ignition pack on top of the engine. the plugs would be under this.
What sensor could cause no spark on a 1995 caprice?
No spark would usually be the ignition coil.
Can new spark plug increase hc emissions?
not really.new spark plugs should help to decrease hc emissions hc emisions are caused by unburnt fuel which is usually caused by faulty spark plugs or faults in the ignition system which would cause the engine to misfire creating a rich mixture ie high hc (hydrocarbons)
What would cause multiple misfires?
Wet/damp/faulty ignition wires, contaminated fuel (water), worn out spark plugs.
Why would your spark plugs be loose?
the engine is constantly vibrating and it dislodges the spark plugs
What would cause no spark on a 1999 Honda Civic EX after replacing spark plugs and wires?
Likely Culprits: Bad Coil. Bad Ignition Control Module. Great Resources:
What would make a 1968 mustang have a no start?
You could be out of gas or not getting fuel to the engine, or you could have an ignition problem. To check for spark to the spark plugs - remove one of the wires from one of the spark plugs, then put a large paperclip in the wire and hold it just above the engine where you can see the spark jump (I would hold the plug wire with a pair of rubber coated pliers), crank over the engine - if you do not get ny spark then you have an ignition problem. Check the ignition points under the distributor cap, they may need to be set to the proper gap.
What are coils used for?
An ignition coil (also called a spark coil) is an induction coil in an automobile's ignition system which transforms the battery's 12 volts (6 volts in some older vehicles) to the thousands of volts needed to spark the spark plugs. This specific form of the autotransformer, together with the contact breaker, converts low voltage from a battery into the high voltage required by spark plugs in an internal combustion engine. In older vehicles a single (large) coil would serve all the spark plugs via the ignition distributor. In modern systems, the distributor is omitted and ignition is instead electronically controlled. Much smaller coils are used with one coil for each spark plug or one coil serving two spark plugs (so two coils in a four-cylinder engine). These coils may be remote-mounted or they may be placed on top of the spark plug (coil-on-plug or Direct Ignition).
Can a bad ignition coil cause a car not to start?
yes once the ignition control module heats up it would cause the vehicle to stall. usually after it cools down the vehicle will restart again.
How do you replace the spark plugs on a 1992 Chevy Camaro?
Same way as every other car. Pull the ignition wires off of the plugs, one at a time, then use a spark plug wrench and a socket to loosen and remove the spark plugs (Twist them to the left like a screw) Put anti-seize on the new spark plug's threads, then hand-tighten it into the hole the old one came out of, then tighten with the spark plug wrench another 1/8-1/4 turn. Put the ignition wire back on, and move on until all the plugs are changed. I would recommend changing your ignition wires at the same time as the plugs. Also, if you can't reach the actual plugs with the wrench, you may have to pull the engine, which is possible if you have the LT1 and big hands.
What purpose does the ignition coil serve?
The ignition coil increases the voltage to the spark plugs. Without this increase in voltage the spark would not be formed in the gap of the spark plug as it would not have enough voltage to jump from one electrode to the other. All spark plugs have two electrodes, a positive in the center of the plug, surrounded by a ceramic insulator and connected to the coil through a distributor, and the negative attached to the screw threads of the plug and grounded to the engine block to complete the electrical circuit.
What kind of spark plugs should be used on a trailblazer?
I would recommend the OEM spark plugs, AC/Delco. Excellent plugs.
