    Speedway Motors 91680921 Details

    So you’ve got your LS engine swap complete and ready to run in your classic, a turn of the ignition away from weeks or months of planning and work.  That’s about the time everyone realizes that older original equipment and aftermarket gauges with pipe thread senders and connectors will not plug into the LS platform of engines.  Water temp and oil pressure ports on the Gen IV engines are a metric straight thread with an o ring seal.  Speedway has you covered, as usual, with these easy adaptors to make your gauges work. 

    • 6061 aluminum fitting for no corrosion of dissimilar metals

    • Designed for oil pressure gauges
    • 16mm-1.5 Male

    Overall Assessment

    Customers appreciate the efficiency and practicality of our product, specifically citing its compatibility with factory sending units and ability to facilitate oil pressure gauge set-ups in LS swaps. The product is commended for its high-quality build and convenient installation, which requires just a standard socket. User satisfaction is evident in their willingness to repurchase; customers even recommend it over alternatives, praising its unique features and functionality, such as fitting perfectly in place of the original sender, even when PCM doesn't require pressure monitoring.

    Since the pcm didn't need to see oil pressure, I just removed the original sender and put this in its place.
