NGK extended reach spark plugs

Product Review (submitted on March 14, 2019):
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.
