its surprising just how much sh*t you suck in on trackdays.

i run my m3 without headlamps with just mesh in front of the air filter.i have had some running problems where the car runs very flat and have ended up removing all the inlet manifold,had the injectors cleaned,new fuel lines,filter,press reg,afm,lamdas.

just built it all up and was about to refit the induction kit so decided to clean it up a little and the cone filter inside was completely blocked with thick shit-as this was the only way air could get into the engine im presuming this was the original problem!
how stupid to overlook one of the basic things!

its been cleaned out overnight and you can now see through it,so im hoping it will al be fine when back together now.
