The Holley (534-10) coolant temp sensor seems quite expensive at $34. I understand that the LS style can be used. Is there a particular part number that is recommended? Any downsides?
Same question about the 100 psi sensor (554-102) for oil pressure use. Is there a more reasonably priced alternative?
Is there something special about these Holley branded sensors that make them so expensive (like with the WBO2s which have a special calibration)?
