Injen Installed-HELP! Quick advice needed!

rvruggiero · 04-03-2013, 08:17 PM

Hi. Today I installed my injen intake on my 06 330i. Followed instructions to a T. I've had intakes on my G35 coupe and other cars before and noticed that this one seems much louder than in other cars-is this supposed to be the case? It does sound good, but it's almost deafening at 3500-4500 rpm and it does seem to drone a little when cruising around 2k rpm. Is this normal? Again, it sounds great but it's almost like it vibrates the interior of the car around 3500-4500 rpm even when I'm not pushing it hard or accelerating quickly.

The directions said not to plug in the vaccum line for the 330i...so I didnt, but I wasnt sure-should I plug that into the intake or what?

Thanks!

I just installed an Injen SP series intake on my 09 328xi...Mine sounds the same way around 4 grand, and I must say I can't complain

Have one on my 328xi and yes it does sound like that, I love it

Okay...for some reason I thought from reading reviews that it would be a nice increase in sound but wouldnt really be "loud". This injen SP is loud! I figured something was wrong...leak, or vaccum line, or something was off. Curious-did you plug in the vaccume line or leave it with the cap on?

just plug it in and see if the noise changes

Now I'm having a vibrating noise in my dash at idle coming from the center of the dash.... Any ideas?

try tightening your strut tower braces

rvruggiero · 04-05-2013, 11:15 AM

I will check on that-any other ideas? I'm guessing its related to installing the intake as I didnt hear this before the install.

Wondering-- I didnt get a bracket with my injen to relocate the power steering reservoir-could this be it? I noticed the two hoses rub up against the intake by the MAF sensor, which i dont think is a huge deal is it? It's not like they are going to be moving all that much or slamming the sensor... but thought i'd ask.
