Injen Intake - 6 Month Review

It has been about 6 month now since I purchased the intake for my E92 328. I really like the sound from it compared to stock. I do feel some what of a difference when I changed it between stock (few times for dealer service).

Although it is a great product, I found a problem dealing with this intake.

Since the intake is only held up by the black, rubber piece and a clam that connects it to the engine, it shakes when I accelerate moderately? Thus rubbing against the black bracket on top of the intake. It also rub against the bolt on the bottom of the bracket when I lowed the position of the intake. I have tried repositioning the intake a few mm at a time, but still couldn't find the perfect position for it to not rub.
Due to the rub, I should have holes on my intake within a month. Oh wells, time for a different one.

About me:
1. I have tighten clam that butt up the black rubber and the intake to the best of my abilities.
2. I don't accelerate that hard. I shift at 3-4k rpm 95% of the time.


I hope this isn't a repost. Please leave your feedback and your intake statuses. If anyone needs pictures to understand what I am talking about, I'd be happy to post them within a day or so.

Edit* Pictures on post #6.

is the E92 and E90 engine bay a little different?
because the only part of my intake that is in contact with is i think the bulb wires right behind the headlight housing and occasionally the power steering pump which the instructions has said that we should turn the clamp sideways. besides that i don't have any odd contact for my intake.

i occasionally open up hte hood and check on the intake for the fitment to see if still fit or loose.

edit: ok, i see umcool911ok also has the same problem with the 330i. let me look back into it. and thanks for the heads up.

I have clamped it sideways. It used to rub against that, but now it's rubbing on the bottom.

what frame?

if it's what i think it is, you can either 1, loosen the metal clamp thing or 2, switching the tube around?

not sure if it helps at all..

When taking car to service

I was woundering if you would have to switch to the Bmw intake when taking your car to services?

I put back the original because if they find anything wrong with your car, they'll try to blame it on the after market parts.

That is where I am rubbing against, but I do not have one finger space. If most, I have only half of that. But since I've seen this picture, I'll try to see if I can push the intake more inward.

Thanks

maybe you should try twisting the intake lower with the filter lower to the engine bay??
