LF: performance parts for my bmw 540i 4.4

[tuner117]

Hey guys, have been looking for a cheaper supercharger for my bmw, tho that being said its harder than it looks, i am new to superchargers and v8's as to i am more of a import guy but decided i would give er a go, so if someone has some information they would like to share about either 540i's or different performance mods and things to do to it just comment or dm me.

Thanks guys
Brayden
