I ask because the same part number is quoted on ebay listings which range in price from £40 to £140. The common make looks to be Denso, which they class as 'original'. LR want £130 each. I bought the two pre-cat sensors on ebay at £40 each and the error is still showing. the mechanic did say that they looked different to the old ones, more holes in them etc.

Can someone point me in the direction of the proper ones ?

I really don't want to pay £130 each if the Denso ones on ebay are exactly the same at £40-50 each

anyone know the correct part numbers for both pairs of front and rear sensors for 4.2 S/C ?  RR Sport Supercharged Vesuvius Orange 4.2 V8 First edition

Prefer RR Vouge S/C but they don't do Orange !
