Crap. You're right.

Now if I could just get some filters for my motorbike, bicycle, boat, atv, snomobile, another that matches my jogging outfit.......

And what about all my vehicles that don't even HAVE a filter?

:rolleyes:

Your X5 is better than them, the air inside those vehicles isn't as clean and you probably smell more outside odors. :D

It is a $20+/- part that needs replaced every year or so for the air to be cleaner and smell better. Why not replace it?

I'm about ready to pull the trigger on this DIY, here's what I looking at buying:

BMW E53 X5 00-06 3.0i 4.4i 4.6is Replacement Radiator Fan | eBay

I am confused. Why is your inquiry of a DIY in this thread? And are you just saying you are going to purchase this fan and install it? Or are you asking us what we think of that fan?

Wow. I goofed! Had a couple of windows opened and replied to the wrong thread. I was actually trying to get some feedback on the fan from another diy post. Please ignore.

As for the filter, I've agreed with many here...use Mann on Amazon and you will do just fine.
