I wanted to replace the intake manifold on my Civic Si 07 that I drive every day. I bought a used car and the previous owner broke the intake manifold with no vacuum fittings and that was very limiting. I wanted to keep the factory airbox so I decided to try this tube although it's a bit pricey but as they say buy once cry once. This tube made a difference in the midrange, especially after the vtec crossover. I can not compare with the drain, because my self-made. Definitely looks cute under the hood of my Blue Pearl Fiji Si and was very easy to install. I would definitely recommend this hose to anyone who wants to keep the factory airbox.
