I placed these into a 1994 Na in preparation for the turbo build and saw a 3-4MPG average increase and could feel more torque even when N/A. Once I installed a turbo setup 10k later they were flawless even at 15psi. I highly recommend these plugs.
- very good
I had been chasing NGK numbers trying to figure out what was best for my NB2. After I bought these, I worried that they were wrong so I sent an email to Flyin' Miata. Within minutes they assured me that I had the correct plugs.
- What a surprise.
Shocked at the difference. Stock 2002 NB. I was surprised at the difference in performance. Much better than just a new set of plugs.
