These type of coils are certainly not a regular "disposable" part like spark plugs that you normally just throw away after a certain amount of mileage. Going through 8 coils in a short amount of time is very suspect.

Also, I would echo the sentiment that if money is really tight, go get some replacements at a salvage yard rather than aftermarket. This is one of those cases where OEM is really better. Sewell is a good online dealer where you can get factory parts for substantially less.
