The cost to replace mine was $900 part + $200 labour, quoted by the offsider.
When I dropped off the car the main mechanic said he could probably do it a bit cheaper, but the job took him 4 or more hours so he stuck with the original price.
I don't know if the part was original it came in a box branded Denso though.
I think unclipping the rear connector was a real drama with two of them attacking it from the top and through the wheel arch.
