Any1 know what this part does and its benefits? thanks

aFe Throttle Body Spacer for BMW 135i/335i/535i L6-3.0L turbo: http://www.wstoshop.com/servlet/the-...-spacer/Detail

 

more volume = more air into engine. does it work i don't know.

bigger throttle body has given gains for cars some significant ~70whp, just don't know about these.

 

Can it be used with a stock setup?

 

my guess yes but i dunno i'd talk to afe and see

 

Spacers give you an effective small increase in your intake manifold volume. A sizable spacer on a carbureted or throttle body injected engine will tend to give a small boost in power. On a modern electronic fuel injected or direct injected engine, it will make you go faster only by lightening your wallet (though the weight of the spacer probably more than makes up for that).

 

So do you think I should go for it?

 

^no

 

Absolutely useless. Even the dinan throttle body is useless. You need a combination of laminar and turbulent flow for the TB.

 

DO NOT get this. We used the prototype 1yr ago and it didn't do anything with my cousins 335i. :thumbsdown:

 

thanks guys for the heads up
