How much better mpg do you get with a bfi?

 

I will let you know as I just filled up with a tank of gas and recently did the BFI. Prior to the BFI, I was getting 20 mpg with 90% Freeway Driving.

 

Alright thanks a lot did you make the bfi yourself?

 

I did mine and used several links to get my own ideas. Try http://planetsoarer.com/BFI3/bfi3.htm and http://www.lextreme.com/BFI.htm.. You can use whatever you like, just be creative. I used all aluminum for the plates, and the cover.

 

Yes. Its fairly simple. The only time consuming part was crating the top cover heatshield template. I too used an aluminum sheet bought from Lowe's. I now have a template for specifically for the SC300 for those are interested or are lazy to make themselves

 

I am planning on building one of these ASAP but wont have time to do it right for a few weeks. However, I was thinking of doing something to get me by for a few weeks and wanted to know if it would do anything at ALL.

I was thinking of either doing just this

and leaving it as is for a couple weeks, this would result in similar effects to the K&N kist that bolt right onto the MAF I assume.

Or my other thought was basically doing the above but then running some hosing (which I have from a home project) from those 3 holes down inside the front fairing to get more air.

In your collective opinions would either be worth the effort or should I just leave it alone till I can do the whole job the right way?

 

Sorry for newbie question but what does BFI stand for? Is it some sort of CAI?

 

Big Frigin Intake LoL

 

Ok lol. Feel noticeable gain?.

 

Yep and better sound. It works better with an aftermarket exhaust.

 

ur wrong noob lol big F###### INTAKE LOL

 

Just put the lid on top, Shield on the side, Cut out the front of the box and thats it. You will notice an definite increase in intake noise (a good one) and a slight decrease in fuel consumption (depends on how you drive)

 

Forgive the noob question, but is this useful for a stock VVT-i 2JZ-GE?

 

Bump (sorry!). Anyone have an answer to my question?

 

it useful on any car

It makes the engine "breathe" better

I have it on my stock 94 SC4 - I really don't know how much difference there is in HP or power, because I did all three things together - The car is def. super powerful now, and the gas mileage is BAD!

160 miles --> 15 gallons (FAIL!)
