New OEM Spark Plugs – 06H 905 601 A / NGK PFR7S8EG

 

New OEM Plugs

There is a new part number for the OEM spark plugs – 06H 905 601 A.  They are made by NGK now instead of Bosch.  The corresponding NGK part number is NGK PFR7S8EG.  This new plug is a double platinum laser plug that is also one step colder.  I guess all those people advocating one step cooler plugs were correct.  Anyway, I installed these last night and the engine is purring as always.  The BKR7EIX’s I had in there had begun to show erosion at the ground electrode and the gap had opened up considerably.  I did not notice any real change in performance, slightly smoother idle is pretty much it.  I’ll report back if it affects mileage considerably.

This plug supercedes part number 101 905 631 H which superceded 101 905 631 B.  The previous part was a Bosch FR6KPP332S.

Anyway, here are some pictures showing the new plugs.

*Update*

Some more information regarding the newer OEM NGK sparkplugs from a forum member on Golfmkv.com:

When comparing to a bosch stock plug many goof on the difference in how their ranges work. Because of that some cross references out there show the 6 heat range NGKs being stock. If you go to NGK themselves and check THEIR application guides it shows a heat range 7 as being stock.

    • The socket size is the standard 5/8″. Get one with the little rubber spark plug retainer.
