Can anyone suggest the best performance spark plugs to use in my A4. It has apr stage 1+ injectors. It has a manual trans and It's my daily driver. Thanks in advance.

the bkr7e is a good choice but needs replacing about every 5-8k for optimal performance. the BKR7EiX using iridium last to like 30k.
copper plugs all the way, they fire easier and conduct better, need more changing by me FREE!! the harder less conductive plugs came from the required OEM warranty, not the better performance they claim, stealers, they DO NOT work FREE!!!!
