OK i was looking at the intake on the t/c today to try and see what i need to piece together a cone filter set up. It looked like just calmping a cone down to the MAF but then i noticed a hose comming off the intake inbetween the oval air box and the maf, it went down to a box that looked like on line came out of it and to the passenger side wheel, what is it and is it important
that is emissions.. it is the carbon cannister
Is it bypassable?
