Today,i need to speak about spark plugs. Yes those little ceramic plated rods,that fit in the engine,and of cours,give sparks and bring the car to life again.
Everyone changes them at (usually) the time plan stated in the owner's manual,but i've seen from experience,that it pays to do that sooner.
The cost from 15 to as much as 80-90 $,especially those iridium sparks,wich i don't find really up to the promise from the manufacturer. Just put the one sugested by the manual- be advised,the manual,not the dealer,as they tend to sell you anything they have a contract on,not what you need.
Why should you bother replacing them? here's why: Your car gets more MPG,swifter acceleration response time,shorter start up time,and most of all,you minimize the risk of having a dead spark plug in the middle of nowhere,Hillbilly County.
If you like to have dirty hands,you can change them yourself,all you need is a spark plug key,some copper grease,and maybe,in a perfect world,a dynamometric key. Dont want them over-tighten like my father wallet on new years eve !
Don't go the the other side either- changing them too soon. They don't grow in trees,and you're not made of money,you know.
