Randy (empowerd), Thanks!

After replacing the K&N cone style filter w/ heat shield back to the original stock air box w/ K&N drop in filter, my car's throttle response was very crisp and from 4K RPM up it just kept pulling and pulling like you would not believe. Amazing combination with the bored out throtte body you help me do. Thanks! I can't wait to dump this thing on a dyno.

On my old cone style filter it felt very sluggish in the city under 100km/h. On the highway it felt only slightly better. I love the flat pannel filter and your 100% absolutely right about 318's intakes, the K&N flat pannel filters w/ airbox work way better than the cone style. At first I doubted your friends 130hp @ RW on his "ti" but now I can definitely feel it.

Bryan

No prob Bryan.... glad all the bolt-ons worked for you. All I did was relay what Shawn told me and I guess now you confirmed it. This thread also helps to clear up some questions other M42 owners might have. I'm moving it to the Performance Section.

would it work with mine ?

I find my throttle response very sluggish. Is this true for all 6cylinders? Would your mod work on my car too? OBDII?

Did you have it done before the Niagara Cruise? Cuz your car sounded very responsive when you rev at idle.

Is it possible to get that "Honda" throttle response on my 328? I previously owned an Integra (GSR motor), and it was totally different. I'll admit ... I stalled the BMW a few times before I got used to the throttle.

do you have a chip in it to get the most out of the bored out TB? how much work did that involve? how expensive? will it work well with a stock chip. i have a drop in K&N and Supersprint exhaust with stock chip now and id like more power without going crazy (motor swaps, forced induction, bottle feeding, etc.) so this sounds like something feasible.

Cone filters are for Honda boys.. they don't work any better then the factory air box on a BMW.. remember guys the tech's over in germany put a lot of work into the intake system your not gonna get much better. if you want better throttle response try a lightend fly wheel and a free flowing exhaut.. then if you've done that the olny thing i can think of is light weight engine internals and head work. I don't see why a chip would help much but it kinda seems to work
