I have replaced sparkplugs myself, and they are around $2 a piece. So around $12. However, you can buy more expenssive spark plugs. It takes a while, but you can do it yourself. Good luck!
Their is no 1993 olds alero the first year is the 1999 sorry.
Looking at the top of the valve cover there is a cover in the center. The spark plugs are right below that cover.
on a 2002 olds alero 2.2 4 cylinder ecotec the spark plugs are located on top of the intake, under the cover that gives the engine size,it is possible that yours may also be located under this cover. All you have to do is remove the four bolts on top of the cover and your plugs will be under there.
For the 2.2 engine:ACDELCO Part # 41105 For the 3.4 engine:ACDELCO Part # 41101
Alero
if its a quad 4 engine, you must remove the top engine cover to reveal ignition assembly. not a cheap part to replace. replace plugs only when misfiring.
