New to Volvos.I hope I haven't asked a question that is answered elswhere. I've looked through the threads and didn't find anything on this. Just purchased the car to replace a totaled car for my daughter. The plugs at that came in it are FOMOCO. The parts store looked up the part for the 2007 and it was too short. The part for the 2004 is the correct fit. I have checked it on a couple of websites and found the same mistake. The manual doesn't give a part number for the sparkplug but recommends a Volvo part kit #30650379 and gives a gap of 0.027in. Looks like Volvo is secretive about the plugs in these cars. Any advice.

 

Welcome to the forums. I would buy the plugs from Volvo. They are very good quality and you will not have to worry about them fitting or if they are compatible.

Thanks for the advice. I did that last evening. Also changed air filter. $30 from the Volvo dealer and $49 from the parts store.
