This is one reason why I joined this forum. I wish to do away with all the snap on pretty plastic pieces that retain heat/limit access to the engine.

I was hoping there was already a thread or two about a quick and easy (cheap) way to route tubing from the TB to air filter housing that is not an eyesore. I'm thinking about doing away with that plastic housing too. I need to come up with a ducting material that won't be prone to heat sink. And I don't want the typical aftermarket CAI that locates the filter in the hot engine bay.

Might have to use a different 72mm MAF as the Bu's MAF is integral.

I am not intentionally looking for more power, MPG or throaty sound. But those would be a bonus.

Definitely not looking for a home depot CAI.
