Another weekend, another spark plug job

[jayjr1105]

Because labor is typically the largest part of the job, I tend to replace everything with a kit. Really depends on how the car has been maintained.

On my 2004 V70R, the previous owner changed the oil every 5000 miles with mobil one.

That entire system was clean as a whistle.

On some of the other cars, that had been maintained by the book, the entire system needed to be replaced.

It looks like there’s about a $15 price difference between a set of six OEM Volvo, at about $15 apiece, or genuine Denso at about $12 apiece.

Interesting those seem to be standard Denso twin tip iridium's. That's what I use in the Honda Van and I love them. Anyways, I'm probably set for the next 9 years but I'll keep that in mind. Nice they offer free shipping over $50.

Is that anything like another day another dollar?

No. It’s individual coil on plug. Nothing shared like older designs.

I didn't realize that a precious-metal pad on the ground electrode was helpful for a non-waste-spark ignition system.

Get a diesel and be done with spark plugs.
