How much does it help? Can you feel it?

 

It helps alot. There is more info on it if you search these forums and planetsoarer.

there's like 3 different versions on there i believe.

 

Yea you also get a nice deep grumble under your hood. First and best mod i have done.

 

Agreed, it works wonders. You can really feel it, and there is also a lower and louder tone on acceleration. If you want less vulgarity you can think of it as "Big Flow Intake", "Big Friendly Intake", "Big Fat Intake", whichever haha. Also, if you're into tuning the SC400, take a look at this: http://www.alastair-mcpherson.com/ul...ning_guide.htm

 

The BFI is not about making power so much as it is about increasing throttle response, fuel economy, and giving a nasty growl to the engine bay when you open the throttle more than 3/4 of the way.

Regardless, it is a great mod. It is worth every penny and every hour invested. It will give you the SC400 fever.
