    Just for the record, that box on the snorkel assembly next to the snorkel is the resonator, not a silencer. The purpose of the resonator is to increase torque a bit at the frequencies it resonates at. It was a good idea to let it remain just as it was.

    Now that you have been running this intake for a while, how are you liking it? Any changes noticeable? Positive / negative comments?

    Funny you should ask...

    I am now in the development process of Air Box Tube 2.0

    When I originally put this together, I just assumed that if the tube was close to the exhaust manifold, that the intake temps would be adequate. I'd like to see 75 degree intake temps when the ambient temp is 0. That's just not going to happen with my current design.

    The next design is focusing on isolating the end of the tube to the hole in the exhaust manifold shield... I'll post an update when my next order of raw materials shows up...lol.

    Woohoo, version 2.0. Sounds good.

    Do you have any concerns with it getting to hot? What do you plan on doing once spring rolls around?

    Absolutely...that's a concern I have when you talk about isolating the end of the intake tube to the exhaust manifold heat shield. I think that will be OK when the ambient temps are 40 degrees or below. But with temps above that, I think something like my existing setup (with the intake pipe close to the exhaust manifold but still open to surrounding air) will be OK.

    So ultimately what I'm thinking about is the ability to use a silicone reducer and adjust it up/down on the intake pipe depending on the outside temperatures. I think once spring rolls around and we have consistent 70+ degree days, I'm not sure I'll run any warm air intake at all.

    I know someone else had a warm air intake setup where he ran it year-round with intake temps well above 100. I'm not interested in doing anything that extreme.
