£10.50 used on Ebay. Fiat - MAP / Manifold Air / Boost Pressure Sensor - T-PRT05/A | eBay Or £6 - or best offer + postage... FIAT STILO 2003 1.6 16v AIR PRESSURE MAP | eBay
Wouldn't count on it, my Son had a Punto and parts from Fiat were extortionately priced. We changed the front struts (with aftermarket jobbies @ £30 each) but the 4 bolts that held them onto the axle were so corroded I had to cut them off, Fiat wanted just shy of £50 for 4 x M10 bolts... :Jawdrop:
Second hand £6 Vs about £60 - new Fiat ones are dear I think yes, but second hand market cheap as chips
Looks identical has to be worth a punt as no way would Ducati make such a part they would just buy in from an oem.
