I saw many post about switching stock plug with copper plug....no doubt all the AUDI owner loves the performance of copper plug..but....
I just went to NAPA and they recommend me using iridium plug instead of copper...they said they would never put such a cheap pulg on a high end car like AUDI...
Why is that??? which one should i get??

 

NGK platinum plugs

 

COPPER! Ihate irridiums... your not supposed to gap them either..

For turbo cars I love coppers.

BkR6E's only cost 2-3$/each .. and so what if you have to change them every 3000/5000 miles ... they cost 3x less, and work damn well.

 

I use Bosch F7LTCR

 

Never listen to what people at napa say....
+1 for NGK BKR6E! gapped .028 for chipped, .030 for stock.

This has been talked about too many times.

 

I use NGK PFR6Q. Cost around $15 each and last 40K mi. They are OEM.

 

BkR7E <- This is what I have. I change it evertime I got my oil change. It works great.

 

ya 7e's are one range cooler than 6e right? very important for BT guys like you!!
