Quick facts
- Part: NGK 5547 spark plug
- Fits: 2007-2010 Audi Q7 V8 4.2L and other vehicles
- Condition: New
A misfire, rough idle, hard starting or lower fuel economy can come from worn spark plugs, but ignition coils or fuel delivery can produce similar symptoms. With the engine off and cool, a removed plug with a worn-down electrode, a cracked ceramic insulator or oily deposits shows whether the plugs are the cause. If they are, this plug replaces them.
Fits
This is an Audi S5 spark plug for the 2008-2012 V8 4.2L, and it fits the 2007-2012 Audi A8 Quattro V8 4.2L as well. The 2007-2010 Audi Q7 V8 4.2L takes eight plugs, and the V10-5.2L engines among the other vehicles take ten.
