Maintenance on ignition coils

[artist]

I have a '98 4Runner V6. Is there anything that can be done in terms of maintenance (or refurbishing) on the 3 ignition coils?... or are they basically a throw-away item?

When they go bad, they usually throw a code. I know of no way to salvage or renovate them.

Out with the old - in with the new.

My experience with them is it's best to buy new from a dealer. There are a lot of after-market coils made in China and many are pure junk.

Thanks for the info!
Is "Denso" a reliable product?

Denso supposedly makes the OEM coils for Toyota.

That said, I have seen Denso electrical/electronic parts for sale that look a little different than their Toyota counterpart(dealer part).

Does this mean the Denso part is inferior to the one they make for Toyota?

I can't say.

There are a lot of online Toyota OEM parts sellers that offer discounts.

The boots are replaceable. I'll get you a PN later today.
