    Nice product legit!

    Works really well and easy to install. Reason for 4 stars is gauges aren’t the matching as far as shape. Check the photos for details.

    Satisfied!

    Auction was for #30-4110 but received #30-300 X-series. Thank you! Gauge works flawlessly! Compare to the old gauge in pic, the X-series looks mean and displays bigger numbers 3or 4 digits.

    Good gauge bad sensor

    Gauge is nice and works well, the wideband 02 sensor that came with it stopped working after a few minutes, had to order a new one.

    As expected

    Haven't installed it yet. But make sure you specify what bezel And faceplate you want at checkout. Everything else checks out though.
