Has anyone done a bfi on a 1LS? It seems like everywhere I look they have been done on sc400's and I saw one for a 2LS, but that has a different radiator cover/snorkel. Any help for a 1LS would be great.

kinda hard but im sure someone has done it. we have no room under our intake unless u cut a hole of some sort.

intake solutions have already been discussed, please search

a lot of the stuff us 2LS guys do (found in the 2LS sticky) are somewhat applicable to 1LS as well.

I have searched. I have two issues, one is the snorkel/radiator covering on the 2ls which acts as a roof for the airbox, the other issue is how to get cold air to the box in the first place. I read that you remove the headlight gasket but that seems awfully restrictive.

u could read lexkost's mod and try that.....that way no restrictin to worry bout.

I already read lexkost's mod, but I also read that the K&N filter is more restrictive and filters less, so I was hoping to stick with the stock filter. So if I removed the gasket around the headlight will it provide enough airflow?

read up some more buddy, u can do the Lexkost mod with your stock filter, in fact, thats what im running.....

ok, thanks for putting up with my noobishness lol.

i didnt even need any rubber trim.. the stock filter clips back on fine.. if you want to leave the rest of the factory intake on except the plastic canister you'll be getting soem "cold air" from that as well

you'll also be getting some hot air too, thinking about trying to block off the hot air entrance and keep the stock "ram air" thing in the front. probably gonna do it tomorrow.

Ls4hundred

What "ram air thing" are you talking about?

LiCelsior

the thing in the front, on top of the grille. im thinking about expanding the opening too.

I think you are talking about the snorkel on top of the radiator.

yea the snorkel, i just think of it as ram air lol.

tried to make a sample one with cardboard to try and block off the hot air, and its just impossible. theres too many wire harnesses around the intake and its a tight fit.
