Whether it's cruising on the highway or tackling challenging terrains, the NGK spark plugs have enhanced the overall driving experience of my Audi A6.

Great plug

Worked flawlessly for my motor. Normally theyre gapped to perfection but it never hurts to double check! Always recommend the iridiums. Best bang for the buck, of course theyre easy to install.

Instantly noticed an improvement in performance, but then my old plugs had some carbon build up. Can't go wrong with NGK plugs. Very satisfied and highly recommended for this 2.0t version. NOTE: do yourself a favor and lube the threads with anti seize. Pays off next time they need to come out.

Great spark plugs

Using in VW EOS Hybrid K04, w/ every mod and APR 3.2-104 Octane Tune with E30+ Water Meth Injection. Lasts around 19k Miles. APR recommended change of 15k. Better than Denso IK22 which only last 10k-12K at best.

Works on my S2000 turbo build. Love NGK

Best spark plugs for a turboed or supercharged Kseries engine My car feels a lot more powerful 👌💯
