2002 XC70 Spark Plugs and wires for 2002 Volvo XC70

Hello. I see there are many posts about plugs and wires, but with technology always changing I thought I would update this question.
What are the best plugs and wires for my 2002 Volvo XC70?

I know using the standard Volvo Plugs (Champion RC8PYP-8 - 0.028"-0.032" gap (0.71mm) - torque 25nm) are the recommended choose, but what about the E3 plugs?
What is the part# for the wires, and do they need to be replaced as often as the plugs?

Any help would be appreciated.

Cheers!
Stephen

No wires on a 2002 model. Coil on plug technology was used after 1998 on all 5 cylinder models.

What are E3 plugs? Lots of options for a 2002 depending on your budget. I used NGK V electrode plugs recently on my 2002 XC70 and they seem OK.

Platinum or Iridium are the next steps for longevity however I like to remove and clean them at least every 35,000kms or 20,000 miles and see if they're a good colour range.

I've always just used plugs from dealer. w.r.t. wires: as mentioned it's a coil pack on-top of the plug. I've seen people replace the coil packs around that age pre-emptively in case they are getting weak.

I had a coil pack fail recently on my 2002 S60 & just replaced the one bad one. So it's probably not totally unreasonable to replace them if you really want, and perhaps it does improve spark, and it might avoid you getting stuck somewhere or waiting on parts. Or just keep a spare one on-hand...
