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 replaced the OEM plugs with NGK, they lasted about 15,000 miles. Burger Tuning told me that 15k is about all you'll get out of NGKs in these cars.
Get rid of those ASAP. These are prone to breaking their ground straps. Myself and many many others have fell victim to this.
During a 300 mile trip in 100 degree weather, my car decided to start shaking horrendously, and the check engine light started blinking. Ford Pass notified me of a cylinder misfire. Apparently the spark plug was missing a piece, and there was extensive damage. Metal debris throughout the engine, turbo charger, multiple lines and drains. Everything has to be replaced.. but luckily it’s all covered by the 5yr/60k powertrain warranty. Such a huge failure at 46k miles is disappointing. I love the car but definitely have trust issues now.
