Subaru Liberty (year:2000) 2.5 RX Spark Plug Selection and Place of the fuel filter?
Hi all, I'm David. I own a Liberty RX 2.5 year 2000 and I want to buy BOSCH spark plugs and I'm confused. Which one will be the best for fuel economy? 4 nailed platinium ? 2 nailed or 1 nailed ones? Currently there is NGK with 1 nail on it.
As far as I know from my past BMW 320i (1994) Bosch spark plugs always give better fuel economy rather than NGKs.
I will be very glad to read your suggestions as Im new to Subaru after several years of BMW experiences.
Secondly, I wanted to change the fuel filter but I couldnt find it. Service says that it s with the fuel pump and can not be changed periodically every 10K kms. Is that right or I should buy and replace the fuel pump?
