I had some concern engine running early August I decided to change the fuel filter, I'll buy it from a shop that bmw 100m from my workplace 90.50 euros with 25% discount, it is expensive because the fuel pressure regulator (3.5 bar) is integrated in the fuel filter sets I do not regret the change because after shaking his flowed like black ink, the filter had just over two years and more than 30.000km, bmw recommended change every two years on the X5 3.0i-4.4i-4.6i-4.8i and mounted also on land rover range rover 4.4i.
Since I bought for future mounting external Walbro fuel pump and Bosch fuel filter screwed connector-type and adjustable external regulator for the fuel pressure.
Hello give us the référence for buying it .thanks
