  1. #1

    Default Holley/NTK 554-100 sensor maintenance?

    Is there any maintenance that can/should be done to prolong WBO2 sensor life? Specifically the Holley/NTK 554-100.

    Nope, and I've never done anything to mine.
    May God's grace bless you in the Lord Jesus Christ.

    The only thing I suggest to help prolong sensor life, is to use the Innovate Motorsports HBX-1 Heat Sink Bung Extender.

    You're darn right! For either Bosch or NTK WBO2 sensor. I won't use a WBO2 sensor without an Innovate Motorsports HBX-1 Heat-Sink Bung Extender.
