Debaffling your airbox....are you kidding me? This adds no power what-so-ever.
As far as I know...similar gains can be had from a good drop-in (Green or K&N) as opposed to a CAI.
People also like a CAI because of the deep sound it helps create at higher RPMS...soooooo...that being said you can have a similar situation with substantially less mods with a good drop in and a debaffled airbox...im not saying the same...but probably similar...
I just wondered why you all think that BMW or any other manufacturer will spend thousands of dollars/pounds/euros whatever, researching and developing a small piece of plastic?
If your never going to use your vehicles in the rain, fine. But if after 30minutes following traffic along a shitty wet autobahn you find a few days later your HWF MAF sensor decides to throw a wobbly because its covered in salt and poop from your previous modifications.....don't go running to get warranty cover! :nana
I have spent years in my job filming results from environmental wind tunnel testing in just these exact circumstances so your car won't breakdown when the MAF gets coated with dried up road dirt, please beleive me when I say there REALLY is a reason for these little odd shaped little bits of plastic that adorn our cars...honestly....because believe me, if we could save 15 cents on each vehicle by deleteing them at the factory.WE BLOODY WELL WOULD!!!! :lol:
