Which Spark Plug to use??

Postby 03xc70 » Wed Aug 18, 2010 3:25 pm

I have a 2003 XC70 Turbo and need to change plugs. This should be a easy process especially after viewing the step by step pictures which are posted on this site. My regular mechanic told me the plugs would cost $75 plus installation cost. Checking my user manual it identifies plug type for Distributor Ignition System. Mine is not a distributor ignition system but operates on an ignition coil for each plug.

Can anyone tell me what type plug I should use and where I can purchase them??

Thanks for your help.

What does your owners manual say? Mine ('02 XC) says Champions and that is what I use or the equivalent NGKs. Both work great.

Cheers,

Hi, I have a 2002 S40 1.9T, I went to the auto parts shop, asked for some plugs, they gave me some "autofire" ones. I noticed that they were gaped at like .04 instead of the recommended .028, I put them in anyway, and the car was really shaking, like it was misfiring. I put back in the old official volvo ones, and it was back to normal.

So my question is, is the shaking more from the gap, or the inferior plugs? Should I try to get the OEM plugs, or try to gap these autofire ones at the correct distance?

Def need to set the gap in your plugs.

The OEM plugs in my gf's S60 are Volvo-branded Denso plugs. I put some NGK Iridiums in there and they seem to work well.

so i gapped those autolight ones and put them back in, and it ran ok at first, but then got worse and worse. At first just would idle rough, then infrequently would misfire, then it would pretty bad.

i guess i buy some new ones... how important are plug wires? do i need to replace those for the 60k mile service?

Isn't the motor direct fire? So no plug wires?

Always use OE plugs from the dealer otherwise you will have strange problems, also use a little never sieze on them. We have fixed many problems doing this and the dealers price is reasonable, make shure you torque them properly. Trust me .

Since '93, the feedback is always that this motor is sensitive to which plug is used. You cannot go wrong, and you likely can't do better, than the OEM plug. Rather than the stealership, get them from FCP or IPD.

Good luck.
