New on this forum, my vehicle 2008 VOLVO S60-T5 (Engine: B5244T5). Begin maintain by myself, confused about the spark plugs. Local dealer used the genuine spark plug part# 8692071, found now discussions that the part# 30751806 is the right one (although on this plug package S60 is not mentioned). Any idea what's the right one ?
Same issue, another thing, the genuine spark plugs are "Made in Germany". I'm quite sure by BOSCH. BOSCH spark plugs we have two part#, FR7DP and FR7DPP10. Any idea who is who compared the VOLVO genuine part# ?
Thanks by advance.

I read everwhere that Volvo OEM plugs were better, but according to this thread the Bosch ones last longer and give you better gas mileage?

Thanks again all.
Jackalope, that's what danomman007 experienced, don't now what was the BOSCH item# used. Answered now from the local BOSCH inporter that the right BOSCH spark plug for the VOLVO B5244T5 is the BOSCH item# FR7NI33 (it's not the FR7DPP10/FR7DPP+ mentioned everywhere).

30751806 is the same plug for the B5244T5 Engine, its just in a different package.
BTW, there is no increased power or gas mileage attributed to spark plugs unless you were first using the incorrect plugs (short ones in a long plug head like the T5 or R). Spark plugs provide a spark to start the ignition of fuel, that's it. The longevity of a plug usually are determined by the metal the electrode is made of. Copper, Platinum or Iridium. In that order. High boost levels may require more frequent plug replacement. Volvo plugs in my experience are always 100% compatible with the ignition system and the nickle coating on the threads provides better corrosion resistance so the plugs have a lesser chance of seizing in the head. The price for the Volvo plug is well worth it. I have only ever run Volvo plugs in Volvo engines in my 24 years working on Volvo's. I have removed countless other branded plugs to improve driveability issues.

Thanks for clarification.
Now I'm with a problem (or not, hopefully).
Reminding,2008 Volvo S60-T5, B5244T5, unfortunately noticed now after 20,000 km the shorter 8692071 spark plugs where installed by
Volvo official garage on schedule maintenance (noticed something not the same but left it). Replaced now by the correct 30751806.
Can somebody clarify me if there is any negative influence, after driving 20K KM with the shorter 8692071?
If yes, there is a way to fix it ???
Thanks by advance.
