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.

Overall Assessment

Customers have positively reviewed the product for its functionality and perfect fit, particularly on LQ9 and LS blocks. The product provides the facility to run an aftermarket gauge effectively. Besides, it excellently supports adding an oil-pressure sending unit to the LS block. However, it is not suitable for LS1/LS6 due to size constraints with headers. Overall, the product outmatches others due to its quality and practicality, as per customer feedback.
