Should i get a fuel sensor (New Stage 2)?

[Pipps]

I remember reading a detailed thread on another forum which demonstrated that the 306 HDi air intake is actually in a very good location, and that aftermarket air filters in most cases made things worse, and at best only add a negligible benefit over a standard air filter. The conclusion was that simple changing the £5 filter twice a year would be far more cost effective. If anyone remembers this thread and has a link then please let me know. Thanks.
