Hi folks,
My 325 seems to be running a bit rich these days and I've noticed that a lot of the hoses are looking a bit past it. So I think a new induction kit is in order. Anyone know how much these are from BMW?
Cheers,

Hoses are cheap enough from people such as Motormec, Euro Car parts, German & Swedish etc.
If running rich is a problem - try turning the inset screw on the air intake housing (aluminium section of the MAF) - this also reduces your CO at idle -and most MOT garages will hook up their CO reader to help you adjust this. (325i needs to read around 135 ppm).
There are many views for & against cold air induction kits so the best thing is to figure out how to feed more air into the standard air box, fitted with a decent panel filter - if this is what you have?

Unless you're going to run a heatsheild of sorts, I'd avoid aftermarket open style induction kits. The BMC is a closed unit and they are available cheap through Sal (M5PILOT).
Other than that a test has proved the std air filter and units are the best design for allround performance for the stock motor.

First thing I'd check on a 325 running rich, is that the blue temp sensor on the thermostat housing is behaving itself.
