not knockoffs, stamped on side and all

I was skeptical because of all you hear about fake plugs, but these are real NGK plugs. Similar to another reviewer on here, I have a 2006 Saab 9-3 Aero with a VTune Stage 2. They work as expected of an NGK plug, and I will be buying them from this listing until they are no longer available.

Ordered incorrectly .. Nice plug..

Worked perfect for me. Used these on an alphaspeed street tuned 2.0 2011 genesis coupe. Gapped at .028

Great value
