AFM removal on M20 what did you do?

Post Fri Feb 13, 2009 6:47 pm

Just wondering what people have done once they have removed the AFM on an M20 really

Big pipe with a cone on the end? Stock airbox with a pipe section.

S14 Airbox?

What did people do then?

Cone filter attached to the MAF unit, going to try sort out a CF replica of the stock box.

replace with nothing and use MAP or AlphaN/TPS or replace it with a MAF sensor. The advantage is better response and performance especially on modified engines.

Miller MAF.

Uses the stock airbox and their own chip.

you got a picture Reggid? UniQ is the prefered weapon if this happens

On a M20 I´d go for a 1bar absolute MAP sensor for the load.

Should be REALLY easy.

Excuse the dirt and crap, i have been doing some rerouting of hoses for the ICV and things are still messy. I am looking to get one of:

You can see a plastic block that i bolted the aluminium flange from M30 onto, it is that thick so i could put a shape bellmouth so air going from the airbox into the silicon hoses has a nice transition rather than a sharp edge which would create turbulence. Its all sealed up with that nasty sikaflex stuff.
