Is there an after market option? NGK, Denso, or any other brand?
Original Audi spark plug not available in my country... I would have to import at high cost.
After being quoted a ridiculous price for OEM spark plugs from the dealer here I spoke to my tuner and we removed the plugs and replaced with NGK Iridium LFR7AIX (2309).
Running for over 2000 kms and all is well. My PFL RS3 is on Stage 1 APR.
