    This is not a bad concept on the whole, dropping the tube as in the second drawing is probably your best bet...

    To much possibility of picking up shit into the intake using the lower ducts...

    Ram air induction doesn't work so well (and with an AFM works even worser-er) So I'd strongly recommend skipping any thoughts of that.

      thanks, yeah I'm not going to bother with ram air.when I removed my filter and hose their was a sticker and a leaf sitting in front of the filter, good thing the foam filter is actually a filter and its really thick foam very similar to a dirt bike air filter.

        if you can come up off of the brake duct like the evo's do that would be a good step. you are just trying to fill the area around the filter with as much cool/colder air as you can so that the colder air is available for the filter to take it in.
        in the design that i got from you, the filter is still sitting in a closed off area. it still takes in air from the headlight and the stock location also.
        by ducting from the top of the brake tube, you are just adding another source of colder air.

        as far as a kit, i am not sure that your average r3v'er can handle doing a little modification to their cars to make it work. cutting a hole to run the air supply hose might scare some off.

          There would be no difference in air temp/velocity between the headlight grills and brake ducts. if anything, the grills are better because of the high pressure area created just above the bumper (same concept as a lip spoiler, high pressure is created just above the flat plane). There's no point in routing the intake all the way down the to brake ducts, all it would do is suck up more shit from the road and create more complexity.

              But just above the bumper isnt grille.. Its part of the valance.. would the high pressure still make it up to the grilles?

                it is not going to jump up over the bumper to get into the grills.

                IIRC DC said something about there being a "void" of some sort there or a low pressure area at that point (the grills)

                  Thats what i thought too.

                  Id think if anything, the brake duct area, with a splitter and lip beneath it.. but then you have to woory about crap getting in it

                    all I know is that at 60mph the I.A.T. starts dropping real quick and even gets below the O.T. which i'm pretty happy with, the grill seems to be a pretty good spot to cool the radiator so why not cool an air filter?

                      I've monitored the I.A.T.s for quite some time and at all the speeds I've hit there hasn't been a speed where my I.A.T.s start rising because of a "VOID".

                      CorvallisBMW isn't talking about the splitter making high pressure and then going into the grills he's saying that the bumper will create high pressure into the grills.

                        i am not discrediting your placement of the the intake "hose".

                        you were talking about comming from a different location, so i brought up the brake duct like i told you about. that method would require some extra modification to make it work to the best of it's abilities.

                        you are not going to collect much crap with a splitter in place. you are just directly feeding air to the filter, not forcing it directly into the filter

                          Well after my old filter got discontinued I kept on selling the kit with a similar filter but not the one that has the clamp on end, so I decided its time to make a new setup.

                          I basically have an infinite supply of these filters because they are being custom made. I'm here for some suggestions not people saying how stupid cold air intakes are, if I can get cooler air temps than the OEM air box, snorkel,headlight shield setup I'm happy. I was really happy with my last kit, its was very unrestrictive,easy to maintain and really got cooler I.A.T's. this kit will be for basically all e30's because the filter is already shielded.



                          So please tell me what you would like to see included in this kit.
                          I can either do it the same way I have been with the hose that leads to the grill or I can have a nice short hose that leads to the triangle betwen each headlight, the triangle method would require the owner to dremel the slots so air can flow threw it.




                          Good Idea on the kit. At what cost though?

                            I don't get whats funny? I've been selling full kits for $100 and i've sold about 10 kits but seeing as I have to purchase the filter,hose,couplers,and adpater I'm still only making money on the heat shield which is almost no profit after every thing is shipped

                              afaik the area above the bumper is actually a low pressure area.

                                At some speeds it is actually in "vacuum" there.

                                And Kamotors,

                                How intricate can you get with forming ABS?

                                I'm thinking you could build a complete housing... We should talk
