Eschew the auto parts figment guides for the user manual recommendation

Volvo or Boschplugs only, please

Ok, IPD site lists a Bosch FR7MPP10 , which is 26mm reach.

Plugs I removed are FR7DP......19mm reach...

Which is right. Car ran for at least 15,000 miles on the short plugs....
Longer plug may hit piston .....

Do you know the entire history of your car?
Doing a little research, the B5244T motor was shipped with earlier 2.4l engines. I've got a 2001 V70 T5 with a 2.3l engine that uses the 26 mm spark plugs. Could this be a junkyard engine put in your 2006 S60 T5?

Maybe the earlier 2.4l engines used 19 mm plugs?

Are you sure you have a T5?

Or maybe you have the B5244T5 engine? The B5244T5 uses 26mm plugs referenced above by velorider.

I will check the Denso site.

The engine is a B5244T. Turbo, 20v T5

What number is in you VIN position 6 and 7? (YV1 M S ## 2 6 5 2 049843)

http://new.volvocars.com/ownersdocs/200 ... n2006.html

52?
54?
59?

52 = B5254T4 S60/V70 R AWD - Automatic / Manual
54 = B5244T5 S60 T5 FWD - Automatic / Manual
59 = B5254T2 S80/S60/XC90 2.5T FWD/AWD, V70 2.5T FWD, XC70 AWD - Automatic Only

I am not by the car currently. But I will check vin. The tag on the hood listed the engine as “B5244T”

But I did try the denso site. It picks a 26mm reach plug for a 2006,S60,T5, automatic- the denso 4704.

Thanks for your help Paul

Plugs I removed are FR7DP......19mm reach...

Per Bosch:
The 2.4L can use FR7MPP10 or FR7NI33.
The 2.5L can use FR7MPP10 or FR7DPP+ .
FR7MPP10 is OEM for both.

Run you VIN number through the Bosch parts finder.
