if i use this turbo 4" inlet how do i keep the MAF and other hoses do they sale a costume one inlet hose? like the 034 motorsports for the gt28 series 3" inlet. or do i have to run a filter of the turbo and no maF? its for a 2000 audi a4 1.8t im just confuse about this. sorry if i make 0 sense lol ahah

 

The car will have to be tuned to run without a maf on bigger turbo setups.

 

so basically im looking at running a filter of the turbo and eliminate all other hoses and go mafless then? if I go anything bigger than 3" right?
