It's time to change the plugs in my 2011 GTS, all the online sellers mention that the Bosch FGR-5-NQE-04 is not for X51 cars.

Does anyone have a Bosch spark plug part number for a car with the X51 package? Also, what's the difference, are the plugs a step cooler?

Thanks!

 

if u r not in a hurry u could remove plug to see exact #, then order online,
takes a few days if u buy from western supplier.

 

2010+ 997.2 with X51 uses Bosch FGR 4NQE, slightly different heat range. Also attached is a Bosch spark plug part number decoder

 

Thanks! This is exactly what I needed. I was able to pick up the plugs at my local dealer no problem.

 

Anyone know if there is a benefit of using the X51 plugs in a Carrera S(with sharkwerks center pipe and tune)? I'd assume it's compatible?

Thanks

For anyone who comes across this thread, make sure you do NOT use either of these plugs in a 997.1 engine. The 997.1 cars use a K length thread (19mm) whereas the 997.2 use an N length thread (26.5mm).

You'll either drive the piston crown into the plug tip or the carbon build up on the protruding threads will rip out the aluminum head threads when removing them.
