BMW Just released a New Part Number for the N54/N63/N74 Injectors
These are categorized as Index 11 as the old injectors (188.8.131.525.261) were Index 10.. They have an enhanced internal filtering and special thermo compensating oil.
I have two full sets brand new in box.. I put a set in my car and you can tell a difference, I can't put my finger on what but the car just feels healthier.
A set of 6 lists for $1,436.10
I can do $1,099.00 Shipped.
PM for more details
