NTK (a division of NGK) is the original manufacture for the NSX O2 sensors. Direct replacements are available at a fraction of the price from Honda (which range in price from $455.00-800.00 for the pair).
Do not confuse these with the "universal" type found. These Japanese made sensors are direct replacements manufactured with the same connector plugs used on the factory harness. We have found these to perform better and last longer than replacement sensors made by Denso or Walker.
