That intake looks great..... i'm gonna make one this winter, but i'm gonna remove the entire stock air-box system and put a conic filter on the end of the L_intake. If you think about it, there would then be no need to purchase the rubber "Hump," the breather fitting and one band clamp, which makes the assembly a little more easier. BUT in the end you do have to buy the new(somewhat expensive) conic filter.
I know that its not the best idea to have the intake sucking in warm air from the engine compartment, but i live in Canada.... the bloody air is freezing most of the year. I'm not really sure how warmer air is detrimental to performance, i guess it has to do with the relative higher oxygen content in the cooler air. Thats why when you've exerted yourself physically you wanna breath cooler air rather than warmer air.
Well, anyhow great intake man keep up the good work.......
