Can anyone advise what are the correct Bosh plugs, per the factory manual for the 2003, 2.7 Boxster engine? I read many opinions about what different people like, but no one seems to specify what the factory specs call for.

Thanks

999.170.207.91 Spark Plug (14FGR 6KQU)

Loren, is this still the recommended plug for the 03-04 2.7? I ask because after I purchased my Boxster I had some much needed service work done and they installed NGK plugs. I'm going to change out the coils (slight misfire on 2 cylinders) and I'm thinking I should install the Beru plugs instead. Am I wrong to do this?

 

Mine is a September 2004 2.7 Tip (last month of production).

Yes, 999.170.207.91 Spark Plug (14FGR 6KQU) is still the correct Porsche part number.

Bosch, Beru, NGK should all work as long as they are the same size, thread depth, and heat range.

The correct spark pl99917020791ug for a 2003 Boxster (2.7 liter) is 14FGR 6KQU.

Is seems that Bosch FGR6KE (7413) is the equivalent of Beru FGR6KQU? It doesn't seem like Bosch has FGR6KQU available?

 

Can you confirm?
