Hey guys, I am doing a BFI setup to my V8 soarer in a week. I have been looking at many different setups and am going to go for the stage 3 (face cut out) setup. I was wondering if anyone sells complete kits, I found a couple on Ebay for $80+, so will probably just go to the local hardware store and get some material and spend a day on it myself.

Christian, ignore those peons and simply type BFI into 'search' and you will find a number of ways to do it yourself for very little money. Not worth buying something you can manufacture from corflute (the stuff which is used for real estate signs) for example.
Any tips before I go ahead and cut my air box open? Does anyone know where to get the rubber seal from (which goes around the edge of the top piece and/or around the cutout of the air box as I want mine to look good and work well, cheers!

buy the stainless steel egg cups at woolies, or get a pce of 90mm pvc. heat the end over a bbq and push it over a bottle/flagon to flare it out. cut to length,and paint black. cut 90mm hole in front of airbox and glue in place.
The flared end makes it look professional.
I think the extra opening gives the max improvement. Not sure if boxing it in gives much more, plus it hides the "good look"

Christian, if you want the best from your BFI, forget the egg cup number as I think it is only for looks. As the best BFI's exclude warm air as much as possible, just take the front of the air box out all together and close in the top and the sides so as to not allow engine bay air in. There you have it. My $1.24 worth.

Consider using insulated rubber (reflective one side, sticky the other) from Clark Rubber, if not for all the panels at least to seal up gaps to keep out warm air.
Yeah doing it Mikes way and will be going to clark rubber to get some material. Is polypropylene good to use as the cover and on the sides to block off engine heat? and does anyone know where I can get the rubber seals from? Thanks for your help!

i purchased the egg cups from woolies a few yrs back. as an alternative get a pce of 90-100mm pvc pipe, heat one end over a bbq and push that end over a large bottle or wine flagon to flare the end. cut to length, paint black and fit to hole cut in front of airbox to suit. will look great.

I'm unsure why some of you guys are bent on getting egg cups. If you are going to insulate from heat you will not see them. Just cut the whole front out and be done with it.

And, post 100, woo-hoo.
Egg cups because I am doing it a bit at a time and not insulating right away and it is neater and easier than a single big hole. Plus I figured the egg cups would be easier to find, and if I don't like it I can make the hole bigger later.
Tom, do you have any pics of a setup like that? Sounds interesting, but maybe harder than a big hole.

michael, if you heat the pvc and push it onto a flagon, the end will start to flare out.heat push heat push until you get the desired flare. it is easy and looks good when painted black. trace the pvc onto the front of the airbox and cut or drill out. wrap a bit of sand paper around a bottle/can and use it on the hole to get a smooth finish and tight fit on the pvc. Cut pvc to length desired and glue in. easy and you have a 100mm flared inlet sticking out ~25mm? from the aibox for "no cost"
