Best plug to use in your 300-600hp turbo/supercharged Honda, and its NGK like stock. Will not cause detonation and will not break off like the worst plugs made in the world - platinum. Everyone knows copper is the BEST conductor with the strongest spark they are just to lazy to change them out as often as they need to :)
Most Liked Negative Review
Wrong Plugs
These plugs might be good but the website said they were exact fit. A lot of headache before a I had a professional discover these were a 1/4 inch shorter then OEM

Put these in my vette when i changed heads. no improvement over the accell shorty header plugs. Longer and less clearance the n header plugs.
Bottom Line No, I would not recommend to a friend
Excellent Plugs
I use these for autocrossing my N/A '97 Probe GT w/ a 4 degree advance. Excellent performance. I don't use for everyday driving, as a matter of fact I install before race day and remove and detune when I come home from the races. They predictably work
Bottom Line Yes, I would recommend to a friend
