Spark Plugs (which to use?) V70-XC70 2000

posted by  someone claiming to be Emission on  Mon Nov 5 16:33 CST 2001 [RELATED]

My wife's 2000 V70 is nearing 30,000 miles so it is time for a minor tune-up. The car has run flawlessly (except for the common blinker/hazard light problem). Next week, it gets new synthetic oil and filter, cabin air filter, engine air filter, and plugs. Brake fluid (ATE Super Blue) and pads were done at 20,000 miles.

I want to replace the spark plugs. What does everyone recommend?

Before someone suggests Bosch Platinum-4's (or something crazy), be prepared with a logical argument for their added expense over OEM.

Oh yeah, I live near Los Angeles, so cold weather isn't an issue.

Thanks in advance.

    Sorry, here's the picture of funky-looking S70 N/A spark plugs.

    Emission, I must back up the people recommending OEM plugs. They are pretty cheap and very effective. I have yet to find anyone who has significantly improved anything by installing anything other than OEM, but I have heard (right here, in fact) many stories of degrading performance and going back to OEM plugs. You don't mention if your car is turbo-charged. If it is not, then the OEM plugs are kind of funky (see picture). I think they are that way for a reason. I got a brand-new set of Volvo-branded plugs from volvoparts.com for something like $7.00. With that price, I felt no need to experiment, since Volvo has already put in some work into choosing the right plug and found a way to make it very cheap. After I put in the new plugs, not mucha has changed, nor did I expected it to. As you see from the pictutre, my original plugs after 27K miles look like they can easily go much longer, but I changed them out anyway since I already had the replacements and they were already out. Next time I don't think I'll be in such a rush and wait until the plugs have at least 35K-40K miles.

    Good luck.

    Hi,

    Buy yourself a set of Bosch Copper plugs. These are the ones that Volvo installed in the car. In 1999 model year some engines came off the line with Champion spark plugs. A good plug for the price but I would go with the Bosch.

    I know I am going to tick off someone with the following statement but I am going to say it anyway. Stay away from the Platinum plugs! They will last longer without flowing but they will also slightly ruin your gas mileage. I have empirical evidence stating such.

    Good Luck,

    Steven---

    oem is best. you're not gonna see more power from some branded sp plugs, so why go thru the hassle of trial n error. using fancy sp plugs will just be another factor to eliminate if n when you encounter some engine problem later on. stick to oem, less worry, less trouble.

    Can't go wrong with the OEM plugs. There's no need in spending more IMO.
