That hose is a piece of shit too. Be ready to replace it again. I bought a $10 hose from AutoZone and made it work however the Cosworth IM requires a different hose be used. Regardless that one lasted like a year on the dot too so who knows.
To delete it probably isn't smog legal but its like impossible to tell. I capped the intake on the intake manifold and ran a dump hose from the valve. Then I capped the spot on the air hose and put a filter on the valve cover. This made it independent from the air induction system. I won't have to worry about it causing a vacuum leak anytime soon
