+1 Very true

So it's better off just to buy the MS air filter alone huh...

Yep I'd suggest so. I think the plain and simple evidence is that the stock intake system is more than adequate for even a highly modified M3 once the restrictive stock filter is removed.

Just like you never go any bigger on an exhaust once you have reached the appropriate size for your application, I'd suggest the same logic should basically apply on the intake. Remember smaller intake pipes mean faster air speeds so it is all about achieving optimal flow capacity AND air speed...

I was surprised to a GT4 m3 still utilizes all stock air box and charge pipe...etc...

LOL..

I was able to be present at the dyno to view the results during the runs. Due to a recent heatwave here in SoCal, we were greeted with a sweltering 101F temperature inside the shop, in which numbers will definitely improve as temperatures are cooler outside.

Here are some comparison shots of the Macht Schnell Charge Pipe vs the BMW stock piece. Here you can see where the restriction is virtually eliminated along with the "accordion" style ribs from the stock charge pipe. The included rubber couplers allow for proper engine movement.

The stock airbox is awesome in the M3, but the dyno shows there is definitely some room for improvement for those looking to modify.

sweet, can't wait to see the results

The other point to look for is intake air temperatures - for example I did some basic testing of the Tecnocraft Charge Pipe and Stock Intake and found intake air temperatures as measured by the ECU were higher for the Tecnocraft product.

Not saying this will be the case with this product and in fact it could be the reverse, but it would be nice if vendors could provide this additional type of data as well.

Clearly what you're seeing is not much of a restriction as you think, otherwise you'd pick up more than HP, not the minor claimed amount more than you get from filter alone.

Lee Rutter (Mathews) who ran a 12.74 in a bone stock M3, ran an AFE intake and it wittled him down to a 12.49 not to mention he gained 2mph to almost 109mph, this to me means alot more than any dyno. .

The AFE intake made good power on my E46 M3 as well, but it also made the car stall if you pushed the clutch in at 60 mph

It was not the best design and IATs were pretty high at low speeds. I didn't like how it made the engine bog coming off the line or in traffic.

Tom, first, I can see that it was pretty hot, the dyno curve was REALLY lumpy even with the smoothing turned up to 5.

Second, I think it'd be much more telling to do a dyno of a drop in filter and then the stage 2 intake, and show the weather conditions for each run (humidity and temp). These cars pull so much timing during hot weather, you're probably not getting very representative results.

As many of us have indicated before, some simple Vbox runs on a flat road would be even more telling, because they accurately reflect what is going on during driving.

Honestly, I can't see a tube with that large a cross section being any sort of restriction at all.

Yes vbox runs would be nice. But if you remember the rpi scoops thread good luck ever getting one. Plus the minor hp increase would probably have no measurable effect on vbox runs.

Thats seems to e the issue.. Im happy spending the $100 for the 6/7 HP Gain. I already have the MS Filter. I cannt justify throwing away my perfectly good MS filter and its 7 Ponies for a new $500 Filter with 10 ponies.

people have spent more money on dumber shit on this forum...at least this one has gains..unlike technocrap :/

You had an early model of the AFE intake. I was involved with the fix for this problem which included a small baffle right after the front intake. The air flow was so great across the MAM that it caused the car to stall. This baffle let the air go around the MAM and it solved the stall problem.

AFE should have sent you out a new lid that would have solved this problem.

I had no driveability issues with my car at all once the stalling issue was solved and it was on my car for almost 4 years, in fact the original owner still has it on the car with no issues and that was over 6 yrs. ago.

Aint that the truth.

[kitw]

So, this is a really mundane aspect... does this intake take away the buzzing resonance in the stock intake? When you stick an aftermarket filter on the stock intake, most people report a resonance at 3000-4000rpm. Does that go away with this?

According to endofanera7, there at least seems to be some noticeable difference from stock chargepipe when it comes to sound. I believe he was running an aftermarket filter before running the MS unit. Wonder if it makes the resonance any louder?

Like what you hear in the video but louder and sexier in person, of course Not only that but as soon as the kit was installed, the car almost got louder in general since I have an aftermarket exhaust system (Eisenmann Race). Before this, I have been itching to delete my secondary cats to increase the sound level of the exhaust system and also gain some additional ponies. However, when combined with this intake kit from MS, I dont feel the need for that anymore.

any dyno yet? also there is only one seller of this intake?

Looks like most gains are due to the hi-flow filter....

There is a considerable amount added from the replacement Intake Charge Pipe also, there a a considerable restriction in the lower portion as seen in post#94.

If there was such a restriction why do you only pick up 3 hp over a filter alone?
