I have spark plugs for my 2001 volvo s80 t6 and i want to put them in asap but dont know the torque rating to torque the spark plugs and also need to know the correct gap in order to install them. if anyone knows it would be appreciated, thanks.

 

I have heard you just leave the gap at what it was set at by the factory. I didn't change the gap on mine. The book value for the torque is 22 ft-lb. here is a how-to: http://www.matthewsvolvosite.com/for...9deb161e38c6b6

 

From online Volvo manual:

Spark plug gap: 0.028-0.032" (0.7-0.8 mm)

Tightening torque: 18.4 ft. lbs. (25 Nm)

 

What brand of plugs did you get? Just curious.

 

The ones in the Volvo package for my 2.9L non-turbo are just rebranded Bosch. I put Bosch Platinum Ir Fusion plugs in mine instead. You don't have to set the gap on any of multi-electrode plugs either. Apparently the distance is optimized and set at the factory. I've been told you shouldn't use plats with turbos though. Don't know why as I've never owned a turbo.

 

Cool, I was just curious. Last time I changed mine I used NGK just because where I work I get a discount on them

 

can i use NGK platinums on my 99 S80T6 ? i used NGK plats on my 97 maxima cause they were recommended and i was really happy with them

i hate bosch plugs

 

Well, the Volvo package explicitly states S80 non-turbo models only. And if you use the plug finder on Bosch's web site they don't recommend plat plugs for the T6 either. So I wouldn't if I were you... but it's your car.

 

ok , i dont mind using copper plugs, but can the be NGK only ?

what is actually recommended for the 99 S80T6 ?

 

Well the OEM T-6 Volvo plugs are Bosch Platinum plugs with Volvo's name stamped on them.

 

I made the BIG mistake of putting in the NEW Pulstar plugs into my 01 S80 and I actually dropped gas millage by about 3 to 4 Miles Per Gallon..I immediately put in the Volvo plugs again..it didn't like them at all...Buyer Beware on the PULSTAR Plugs..they are advertised in Popular Science and Popular Mechanics Magazines..with a bunch of BS...

 

Note it says clearly on the package, excluding turbo models.

 

Oh, and here is the link to Bosch's website. http://www.boschautoparts.com/Products/SparkPlugs/

If you use their part find it'll tell you not to use plats too.

Thats funny your link didn't work but I just looked up plugs through the site for a S80T-6 turbo motor the 1st 2 parts were platinum plugs.

OEM Volvo plugs are bosch platinums.

The Non-turbo motors don't use platinums they use the regular plug with the 4 prongs. The pic you have above is only for the Non-turbo motors. Also alot of shops put the platinums on the Non-turbo motors and never have problems either.

 

Here is the screen shot of the site.

 

the 4 prong bosch plugs were proven to be crap, spark takes the path of least resistance thus it does nto travel through all 4 prongs, just one of them...wasted money

i cant come to the idea of using bosch plugs , heard so many bad things about them... NGK plats are solid plugs, but i guess they would have to be re-gapped since they're not oem equivalent

 

The one the dealer put in were three prong, which are just regular Bosch plats I think, same as in package pictured above. The four prong ones are the Ir Fusions I put in. Bosch site still doesn't recommend plats for the 2.9 turbo... dunno why they do for the 2.8. Anywho, I've been very happy with them in my non-turbo 2.9, quadruple redundant prongs and all.

Here's the Volvo branded ones I pulled out and replacement plugs I bought on ebay (cheap).

 

I put the same Bosch IR fusion plugs on my 2.9 S80, no issues... I felt an immediate difference over the volvos, but possibly only due to those being a bit worn..

 

Supposedly the iridium makes them "feel" like new plugs longer. Figured they were worth a try anyways... guess I'll know for sure in about 30K miles

 

Same goes, I have only put on about 5000 miles since the change so I really wouldnt know until a few years later.. hopefully, with the exception of oil changes, I dont have any maintainance to really take care of for another 25k...
