So, last week i picked up some new spark plugs in the hopes that i would change them this weekend. When i bought them, i opened one of the boxes to make sure they were the right plugs and they were, so i bought them and left.
Then, today, i went to install them, and guess what, two of them were different. Even though the are all X5DC's Two of them came without caps on them. I thought this was weird because i though all X5DC's came with non-removable caps. Am i wrong? or are these two just some type of manufacturing screw up?
Also, what is the correct Fuel filter for a 1990? The one they gave me is a Mann filter with part number WK830/7 is this correct? When i compared it to the one on the car now, it was shorter. This is my first time changing the fuel filter so i don't know what type is on the car now as i can't read it.
EDIT: The fuel filter on there now is a Kayser.
