Heyall,

1.I have an 2002 A4 3.0 and would like to change the spark plugs on it and can anyone recommends the brands and locations to purchase ( Autozone, Pepboys, Kragen ....)

2. Recently my check engine light came backon again,last time it happended,I had the dealership replaced the emmission. But the last fews days, while I was driving I changed gear from Automatic to tiptronic, and I wondered if that caused it? if not what else caused it?

Thanks for all your input

I get my spark plugs localy at autozone. No sense in paying shipping on something that can be found localy unless you live on an island. While you are there (autozone) they can scan your ecu for fault codes to see why the CEL came on. Write down the code(s) and post them here and we will help.

 

onepoint8tee,

what's the brand name of the spark plugs that you got from autozone?

 

Mine are NGK.
The ones you want are NGK PFR6U-11G
