Hi Bro,
For E90 320i PFL.

Anyone modified the air intake manifold, I found that there is only 1 air inlet to the air filter, the other is dummy.
Anyone mod it to 2 inlet ? any different in low end and high end ?

This is the part number... 13717560918 (the one with the BMW logo on it)


Number 13

Don't think it will improve anything ...... And the whole chamber is a dummy as well not just the inlet.

FYI - That's not the intake manifold in the pic.
 
Re: E90 320i PFL Air Intake Manifold

no point to modify ... in fact ... can't be modified
why take the trouble to modify
just install simota v2 (gruppem style) intake ... this product probably discontinued liao ... but still can find in ebay or taiwan/china motoring website or ask local workshop to order from taiwan
anyway, been there done that and i feel e90 best intake is stock airbox + KNN air filter :thumbsup:
very very little effect (only at NSH on highspeed) but the sound is good

Pocket no deep deep leh..

Don't think can gain any hp with drop-in lah, hoping to get a smoother ride nia.

Cheers.
 
Re: E90 320i PFL Air Intake Manifold

Choose filters carefully. Know how many microns is stock and use it as a benchmark the filter you are looking at.

Did some research on this a year back - K&N filter hole is lagi big. That's a lot of dirt getting into the engine when using K&N filters.

For NA engines - IMHO, you have more than enough air going in via the stock filters.

Turbo engines if boosted would justify the need for performance filters in certain conditions.
 
Re: E90 320i PFL Air Intake Manifold


During vy low rpm driving/picking up, quite often there are very obvious vibrations for about 1-2 secs like insufficient combustion & i thought that's because the intake not smooth/breathing properly.. Hence looking at options to reduce the vibrations at low end.

Or it's due to some other problems..?

Good filter 300-400.
Engine overhaul 1500-3000.

I go for option 1 anytime.

It's some other problems ..... And could be a combination of issues.

Re: E90 320i PFL Air Intake Manifold

Anyone mod the intake (The part with BMW logo) from single inlet to dual inlet ?

Anyone used 325 intake ?

Bro, what's the recommended filter for option 1?

I suspect u're referring to open pod huh? Wouldn't that kills the low end when it's breathing hot air from the engine bay?

Thanks.

Like to know if the 323i/325i intake can fit on 320i for the dual inlet?
How much will it cost if able to?

Can fit also no use. U will need ECU to operate 2 stage DISA.

323 got only 1 stage DISA.
