Spark Plugs/Wires?

Post by nadz » Tue May 04, 2010 8:35 am

Hey,
I have a 95 volvo 850, Do I have to stay with OEM parts on the wires and plugs or can I get for ex. NGK Wires?

:!: Don't use any other kind of wires...Bougicord OEM only!

Spark plugs you've got a bit of choice, many reccomend the Bosch Copper plugs as they're cheap and work well. They need to be replaced more often than the Volvo plugs, though.

The only real difference that I noticed with changing the wires on the last car I did was that I got rid of the misfires that came with the Bosch wires that were on the car. When I first got picked up the '94 it had some originals and some individual Bosch replacements. I replaced them all with brand new Bosch wires and the mileage dropped by about 20% and it misfired like crazy when cold and at high RPMs. Replaced the brand new Bosch wires with a new set of Bougicords and it was all good again. If it is running OK now then you won't see a huge difference but they do wear out eventually.

The only spark plug wires I've used other than Bougicords are the 8mm IPD versions. I will concur with others that the best plug you can get for these cars are O/E, but if you are in a pinch I've had good luck with copper versions as well. Otherwise, expect a lot of misfires.

Wires must be OEM Bougicord.
Spark plugs....oem Volvo are the best,but you can use NGK or Bosch copper ones.
