A question about Ignition Coils.

My truck has 218,000 miles and is 13 years old.
The next time I change the spark plugs, in a couple of months, I thought I might also change the ignition coils, strictly on a preventative basis.

First of all, is this recommended, if I'm having no issues.

Secondly, I see prices ranging from about $125 for 8 coils to $125 for a single Toyota OEM coil, and everything in between.

I'm wondering what people who know a whole lot more about this than I do are doing.

 

I wouldn't change them unless you are getting misfire codes. If you do change them, only use OEM plugs and coils. Those cheap ones will fail and are a waste of money.

 

If you have the money, want to have piece of mind, feel like having another .73 horsepower, grab 8 DENSO coils and be done with it. Keep your others for spares.

Or, if it ain’t broke (misfires, coil boot cracking) don’t fix it!

 

I'm at 280K, with original coils, no issues. I did have a misfire, but it was a ground that broke loose, once repaired misfire went away. Ultimately if it aint broke, don't fix it. Amazon and Ebay I'd stay away from, if you purchase your stuff direct Denso, or stealership, would do it online as often times prices are about 40-50% cheaper than at the parts department.
