just to let you all know it is worth calling chrysler FIRST!!
my resistor went west (only working on full speed) my car is a 2002 grand voyager 2.5crd i called chrysler and they quoted..................£20.70 inc V.A.T!!!! yes its true was totally shocked

 

I agree, Mopar oil filter £11 from chrysler, Better than halfords etc. Air filter £16 and fuel flter (spin on) £32 which is now getting too steep!
But wait for it.......cabin/pollen filter £127!!!!!!!!!!! The parts guy told me they don't sell many!
Europarts is £15 ish for the cabin filter.
