Hey everyone i just got a cheap "hi-performance" air filter from autozone. Removed the whole air box and replaced it with new filter. Well the main difference it the sound...it sounds more throaty with a little more power from 65-85. Maybe 1-2hp. Anyway i also got a crank-case breather, and was wondering if that effects the performance, as i cant really tell. I am still curious about the two other hoses attached to the air intake tube. One thicker one goes to the resonalor, and attached to the resonator is a small vaccum line. The other hose attached to the intake tube goes from the end(left side) of the intake manifold(pletnuim) back into the intake tube, i guess to re-curculate unused air. Anyway my main question still remains, can i remove these two other hoses, will i get a performance increase? and if so how should i go about removing air intake recurculator hose? Should i just plug it or let it vent? any info would be aprresciated(imlazy)

thanks,
silas
p.s. Im soo mixed up....is my intake a warm air type or what???
