    You are on a path to re-discover some interesting quirks in the e30 chassis aerodynamics (same for the missing headlamp trick).

    I'll give you a hint though: If you really want ram induction... Drop a tube below the boundary layer.
    thanks, this is just my alternative to the 3 eyed e30's.

        so you are saying that the air travels around the grille area?
        Yeah more info please.

            You're front splitter creates a high-pressure area right above it, near the brake cooling ducts. For the maximum airflow, you should attach the hose there.

              O'rly?

              That's nearly perfect then. I removed the fogs from my BMP front bumper so I can install the BMP brake ducts, then the small "what are supposed to be the brake ducts" are now not being used. So I could open up the one on the driver side for it.

              Although that does put the pick up close to the ground.

              But I don't drive my car in the rain usually, so it shouldn't be a big deal.

                I've been thinking about doing the same thing and attaching it to one of the brake ducts. Then again, I don't have a cone filter, so I hardly care. However, my dad's car does. KA, do you sell M42 heatshields?

                  You need to reserve areas of high airflow for deer whistles.

                        I think what he means is that as air travels between the car, it gets slowed down and bundled up (due to viscous (friction) forces- Bernoilli's equation only applies when viscous forces are negligible). This creates a high-pressure area under the car that is higher than ambient pressure, so theoretically if your engine drew its air from there, it would get more mass than, say, behind the headlight because there's more force pushing the air into a hole than there would be if the hole was elsewhere. Before you think too hard about it, though, you'd have to be moving pretty quickly to build up enough total pressure to see a positive effect, and I'd be very concerned about road debris, water, etc.

                          water isn't going to travel UP the air tube and in your filter, so you're ok.

                            I understand the high pressure thing, this was just an easy convenient location to put it, going from the brake duct require either cutting a hole in the car or a few bends and hope that it doesn't hit the alternator.I was amazed how much room was behind the grill in that area, the hose goes directly from the grill, under the high beam, and straight to the filter( the pipe is very rigid so it holds shape really well.)

                              Wrong again hippie.

                              A close friend of mine blew the motor in his Integra from precisely that, water got sucked up the AEM CAI and into the motor and BANG, no more workie.

                              And if that doesn't happen, explain why the big CAI manufacturers (AEM for example) now put valves inside the intakes before the throttle body to evacuate any water that gets inside.

                                Yeah, I would definitely not want to have the intake tube mounted that low. Like most of us that are on coilovers doing that would mean the tube would be 3 1/2 or inches off the ground, must too close for my comfort.

                                But the brake duct seems like a better compromise.
