hello folks, I am new here, I have a 2012 fx 35, I have a check engine light on my dashboard, went into the dealership for oil change and they also diagnosed my truck. I was told that I need to replace the MAF SENSOR-MAF SENSOR-(2) AIR FILTERS-CLEAN AIR CHAMBERS. The price quotes for both parts and labor is very high. The dealership told me that only they can replace the part because of the computerization. How true is that? I have already search the parts online and got great deals. Do I really need to take it back to the dealership to replace this part?
