A Few Easy (I Hope) e46 Questions I Have!!

Hello all, just picked up a 2002 330xi and it's missing a few things and before I set out to purchase these missing items I want to verify a few things:

1. Is there a difference in solely the air box in e46's varying from year to year, model to model? It would make obvious sense that perhaps certain models with smaller or larger engines would have an air box of a corresponding size difference.

2. Is the bumper trim found on pre-face lift models with the standard bumper (sorry I don't know the technical name for these bumpers) different from face lift bumper trim?

3. Finally, attached to the bottom of the power steering reservoir there is a long hose that attaches to a long narrow metal hose that curves 180* and follows back to the pump. I found that it sits somewhere in front of the radiator (meaning in between the radiator and front bumper) but I'm unsure of how it attaches in there. I've looked at some diagrams but can't seem to figure it out.

I know some of these questions might seem redundant but I don't have another e46 to look at up close to compare, so I appreciate any and all input that may follow.

Thanks to all who contribute!

Sean

Welcome Sean.

You're way ahead with your terminology so far. Did you have a BMW before? Are you familiar with realoem.com?

If not, check it out and you can cross-check part numbers (for example to see what years' intakes exchange). We have a lot of bumper experts here too.

Not familiar with #1 or #2 but #3 is the power steering cooler. If a car even has a p/s cooler, it's usually just a small loop like you see there, nothing more. Most cars don't have one.

Yes, The early E46's (earlier than yours) use a different air box. I think the xi always used the same box as they are all the Later M54 engine.

Here is a diagram for a June/2002 Air box http://realoem.com/bmw/showparts.do?...06&hg=13&fg=20

With RealOEM you can enter the last 7 digits of your VIN and that will track down parts better.

Hey there, thanks haha, I've had a few e36's, e28's and an owner of an e30 right now as well as the e46 so I know some terms. I'm familiar with realoem.com, yes, but when I looked up my model it seemed that they showed a diagram for the earlier model bumpers with my car. I'll give it another look though!

Yeah I figured it played a role in cooling the fluid, but my main concern was how it seats next to the radiator (like maybe there's some kind of plastic clip that attaches to the radiator to support the hose). Thanks for the input bud!

Thanks man, I didn't know that about punching in the VIN # or the last seven digits that is. I'll look into that. Just thought I would ask as there's a junkyard pretty close to here that is parting out a 2000 325i.

Ah yeah that's what I meant, 328i. Thanks.
