Coil packs - preventative maintenance
« on: May 19, 2026, 11:59:29 am »
Hi, looking at doing a full service on my car. Considering replacing coilpacks at the same time with Bosch or genuine ones. I have no history of them previously being replaced. Am I likley to see any improvement in replacing them or would I be better off replacing them when/if they fail.

Thanks

If you have no misfires seems a shame replacing them, but if you do get a misfire it's best to replace all four.
