Spark plug NGK or OEM Audi

I have ngk spark plugs and I went with z1 high ignition coils

if you don't want to pay for VW boxes, NGK ruethiums are a killer deal on rock auto, I've run 2 sets through out alltrack without a hiccup, about 60K total.

I changed

- 4 new NGK Iridium sparkplugs

Now post how much they want to change spark plugs. I've usually seen dealers asking for $200-$250 on a 4 banger. Or I can buy some nice NGK plugs for under $60 and get them changed within my lunch hour in the parking lot.

I run NGK Rutheniums now and they've been excellent handling 30psi of boost with zero blowout even at wider than the .024" gaps that most tuners recommend. Oh and theyre MUCH cheaper at $8/ea vs $40/ea for the NGK race plugs.

I went to colder plugs from ngk and noticed a difference in shift pattern for the better (my car is an auto).

OEM plugs are NGK as well.

I do NGK 6510 one step colder. I do 0.025”-0.026” gap. I had a shop do my last set since I didn’t trust myself. He accidentally did 0.022” and I put them in and they’ve been fine. The other set is 0.018” and idk if ima put them in. Gotta change the one step colder NGK’s at around 15-20k miles. I usually change mine when I start seeing high spark retard. I’m BT 93/E40 with aux.

Additionally I would endorse the use of a Champion or NGK plug. The LG/Torch/random Chinese plugs are a crap shoot. I see tons of failures on them as well.

I’ve gotten fake NGK on Amazon before it’s very possible
