2000 e39 528i oil/oil filter/air filter

So tomorrow im performing my first oil change, im getting 0w30 mobil1 oil with a mobil1 oil filter,
I picked up a K&N air filter but then I was told to get AEM DryFlow, then I was told to get a cone filter because the airbox is restricting and holds back that BMW roar I so desperately desire.
I came here to discuss this with my very knowledgable and professional bimmerfest family for the real best parts I should get for my e39. As I want the top best performance for it but also for it to runs like the champion it is, and I was told to get new spark plugs and maybe a coilpack.
Still a noob, lookin forward to hearing from the best..

Most of us here eschew the K&N, in favor of a stock German filter. Same goes for the other filters. If the Mobil 1 filter is made in Germany, it may be okay.

Many here use M1 0-40. Take your choice.

I like the K&N air filter and Mann oil filter. I use royal purple 15w-40 for my 528.

I think I might wanna remove the stock airbox and replace it with a cone filter, any suggestions on doinf that with those? And I purchased a Manns oil filter and 8qts of BMW 5w30 oil from a local BMW technician, but I do like the fact that so many of you use M1 0w40 and still recommend it, so its obviously good, I only want whats best for my e39 but im still a noob, am I making the right decision? As Ive already purchased everything.. But I still have my reciepts and returning it isnt an issue, thanks again bimmerfest family!

Well after doing some reading, I'm not doing a CAI, I don't even see why they make them if its such a bad thing and Im definaty not putting my bimmer at risk like that. can I put an aftermarket air filter in the stock airbox?

Aftermarket air filters aren't worth it IMHO. If they are less restrictive, it's because they're less filtering. If you want more power at high revs, fit an M50 intake manifold.

Maintenance (such as checking injectors, spark plugs, MAF, VANOS, O2 sensors and catalytic converter are all working properly) is the best first step when chasing more power. Or a louder exhaust, so you think it's faster.

Yeah, it's quite involved. Even removing the current manifold has its challenges.

Woops, I forgot that your post 1999 car has the M52TU engine. That further increases the level of difficulty, and means you'd use the M54 intake instead.

Thanks for not letting me make the mistake of using a CAI and messing everything up btw! MAYBE one day il consider an AEM DryFlow filter but maybe not, I just got a taste I that BMW sound and craved more haha, what are your thoughts on straight pipes? I did a muffler delete and had a piece welded up just long enough to keep emissions from rusting out my underside, it has that BMW sound its just really faint

Poor BMW engineers! They went to a lot of effort making the E39 a quiet and refined machine, but now you actually want it louder!


Personally, I think it'd be a freak occurance to hydrolock the engine from an aftermarket intake (unless it was down at the foglight). My reluctance was more that I doubt there's any performance benefit for a stock engine. But if you're after more noise, maybe ditching the airbox is the way to go.

I'm surprised it's still too quiet with the rear muffler removed. Maybe stand outside the car, get a friend to rev it and see if it sounds nice. If so, then you just need to work on getting more of that sound into the cabin.

I always said this about bikers, that it's *EASY* to make a bike loud; it's HARD to make it quiet.

Same thing with bimmers.

I'm not impressed by a loud bimmer; it's the quiet ones that impress me. But, to each their own ...
