Awesome spark plugs!
Works exactly as noted! I couldn’t notice a power gain, and i am the type of person to floor my car constantly, but it does feel smooth and reliable. Mind you, i only have an audi 2.0T (ea888 third gen engine) tuned with a full Miltek exhaust. Nothing insane like an r8 or anything, but still couldnt feel a significant power increase :( Highly recommend the product if your previous plugs are old and/or starting to give way. The cheap price for genuine ngk plugs, cant go wrong !

I would recommend this product to any and all potential buyers. Plus you would be getting better products at a ridiculously low price.
I have always used NGK products from being a Japanese import mechanic. The wear is less, giving them a more efficient use. Plus they do improve spark.
