Your Spark Plugs’ Condition Tells you How Your Volvo Is Running!

Your spark plugs perform an essential role for your engine and should be monitored/maintained regularly. If plugs fail they can cause all sorts of damaging effects to an engine so you shouldn’t cut corners with these.

If nothing else you should look at your plugs at least every year to see what’s going on in the engine the plug can tell you if you are too rich/lean and a multitude of other things pick up any Haynes manual or similar for a description of the various engine conditions shown by your spark plug tips.

Use Genuine Volvo OEM Spark Plugs

Why use Genuine Volvo Spark Plugs? Let’s be honest, there are times when using an aftermarket part on your Volvo is not only ok to do but reasonable. Take suspension parts like ball joints, tie rods etc, there are a lot of good companies out there that make decent products and some of the companies like TRW, Mehle and Sachs actually make some of the parts that are sold as genuine Volvo. So why can’t I use NGK or Bosch plugs instead of genuine Volvo spark plugs?
Don’t NGK, Denso and Bosch make some of Volvo’s spark plugs?
