Question about Vtec J35
Hi I own a V6 Vue with the Honda J35 engine in it and I have a few questions
Here is the thread in discussion

note one guy posts that for vtech engines the intake tube must be long, but doesn't he mean intake runners? and do you guys think that the idea in that thread is doable.

He is wrong. For high RPM power you want as much airflow as possible, as cold as possible. Thin pipes give you low end power. Obnoxiously long pipes are typically to silence the motor (on certain Honda motors with a short intake the intake will be louder than the exhaust inside the cabin) and generally to piss off tuners and mechanics.
The reason Honda performance intakes are longer is to pull air from somewhere outside the engine bay, for colder air. It hurts throttle response and low end power, but on a 1.8 liter 4 cylinder all you care about is top end power anyway.
That intake pipe going over the engine is 100%, hands down, the worst intake design I've ever seen from a performance standpoint. Even though it's plastic you're still going to heat up the air considerably at that point. I think a short ram intake in the area pointed out by the original poster of that thread would be much better for performance than something using the original design. It's going to be pretty loud though, be prepared for that.

mr. CRX, stop being a dink.
I think a box would do good, but also it looks like you could relocate that coolant line in the third picture to be closer to the radiator. Hard to tell from just some closeup shots though.
