Speedway Motors 91680918 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.

Customers say

Customers highly praised our product for its perfect fit and effective functionality in adapting factory sending units and temperature sensors to LS engines. The product is deemed essential for LS swaps with older GM sensors and specially appreciated for its suitability with vintage models like the '66 C10 and '69 Chevelle. It stands out for its easy installation, avoiding issues such as leakage and unwanted contact with other parts. However, some customers expressed a desire for the gauge sensor to protrude further into the cylinder head. Overall, it's a highly recommended product for its practicality and reliable performance.
