Thanks to all the posts & advice from all CEG'rs,I just purchased & installed both upper & lower Bosch sensors on my 96 zetec(140,000mi) Ford wanted around $120.00 per sensor.....since the Bosch's were about half the price at my local Advance Auto store, I asked the dealership if they would install them too at 120 bucks each...He laughed and said I should use the Motorcraft sensors and then I laughed. The car is running as smooth as when I bought it & I am getting around 32 miles per gallon.That top sensor was a real ***** to get out. Be careful.Buy the Bosch's!
