The problem of butterfly valves on the intake manifold Alfa 159 150 HP

[Giacomo]

does not work more clean by changing the manifold with one without swirl

[blackwolf76]

but what you have to pay... and pay for, the caps cost 2 euros all

[checcosassu]

no saw nothing

[michele30]

can it be that with this problem to the valves, the machine will put us a few more to go?
why? I have a customer that complains of this problem.

[checcosassu]

you could also impact power

[sportknight]

Of course, it also depends on them

[marco]

I wanted to ask a question, but if the swirl take it off in the map, the butterflies I have to physically remove?

[hyrosat]

it seems to me you can remove or leave them open from the ecu, however expect the advice of someone more? expert I had issues with the swirl on my manifold 3 were broken and they were metal

[marco]

ok, thanks a diagnosis of what it gave you?

[blackwolf76]

The important ? rimuoverele physically, being that sooner or later they break and they always end up in the engine, causing serious damage. From the map it would be appropriate to togleirle, but when they are in good condition to avoid disassembly.
