Just get the OE version from FCP. NGK 91006.Bump!
Anyone know where I can pick these up on the cheap? I paid $60 last go around for a set of 4, back in early 2020.
Audi RS7 plugs 06K-998-601-M
I've had these on my tuned 2019 MK7.5 (Stage 1.5 93 octane EQ Tuning) for about 38,000 miles now (car has 47k), and I've recently noticed a drastic drop in MPGs; roughly 2/3 MPG. Haven't pulled these to see what condition they are in, but my gut tells me this could be the issue?? Unless this is pure placebo and another issue rearing its head.
I drive a crap ton of miles (90% highway) a year - about 20,000 miles at this rate.
As far as mpg goes, we moved to winter blends and check tire pressure.
