How often are you guys changing your plugs?

When boosting 1.3 Bar and higher, should the plugs be changed more often?

 

My car is now just over 28K miles; a 2001. I've changed plugs twice.....first time around 15K miles. This last time I had the 30K mile service done at GMG; a sponsor on this board. They also recommended and used the upgraded heat range plugs, I can't recall the spec/name but it's been discussed on the board.

On a high-boost (or nearly any turbo car) the short answer is; yes, change them more frequently.

 

And it's not a trivial job, so also consider changing the plugs
whenever the car is being worked on in a way that you've
already done most of the work to expose them.

+1 JOE....

yes... and Dave... In ur case.. when u feel the misfire... or I say between 5 and 10 K miles.....
once a years for sure...

 

2001's (like mine) came with Beru #5's which do not tolerate high boost well.

Now Porsche spec for all years is the #6. Several brands are used. The

ones you get from your Porsche dealer seem fine. Others like the Bosch.
