Q: Dealer estimate of $ replace my ignition coils & spark plugs? For real? on 2004 Mazda RX-8

Took it in for a compression check which they won't do until the above is done. I have no power when accelerating. I have an automatic transmission.

The retail cost of aftermarket coils is $70 each, there are 4 coils they are easy to replace. Call around ask for good quality parts it will still be way cheaper at an independent repair shop.

Take it to another shop there is no reason for them to refuse a compression test without these repairs. Because you have to remove all of the above to do the test, and they will not change the test resault if good or bad. Second I have a hard time beleiving all your coils are bad and the car is running. The plugs may really be bad but you should also be getting misfire codes and check engine light on. Patrick is also right that after market coils are much cheaper and will do just as good. Independent shops are also cheaper on labor.
