What do you people think? No coil issues but I think plugs should be replaced.
Should I replace coils and plugs at the same time to ensure longevity of my engine?! Or should I just replace plugs and worry later about coils to go out to replace? Out of warranty and no plans of purchasing extended warranty. |

your plugs are probably fine. just pull a rando and check it out. i changed mine at 70k and the only reason i actually changed them is because i happened to have the plugs.
they did not need to be changed =( |

Thanks for quick response. Car runs fine. I do have the plugs and coils but probably wait for signs of them to go out or wait another 10k at 80k to change out. Normal driving, no drag or hard driving.

no reason to change coils unless they need to be changed.

The NGK plugs have been updated twice? since 2007 to produce a more powerful spark. Makes a difference in the mid-range, and worth updating now.
