Review on MAHLE Original KL 66 Fuel Filter: Optimal Filtration for Efficient Engine Performance by Roberto Evans

Revainrating 4 out of 5

Inlet and outlet 516/1 slightly oversized

Fits my 2000 323i. But the inlet/outlet 516/1 is slightly larger. Changed every 100,000 as stated in the instructions. Fuel will leak from the filter. And when I disconnected, more fuel came out of the engine-side hose. I got fault code p0153 O2 sensor slow response, maybe this will fix the problem.

Pros
  • Great price
Cons
  • Modern
