    Hello, this is my first post on this forum. I'm currently working on a E46 320I M54B22 that had an air leak, I think at least. Had a weird sound coming from the IM in the area of cylinder 4, 5 and 6. Also has a bad idle and misfire and so on. No fault codes on any sensors except o2 high...

    Recently decided to change the CCV system on my E46 330i since I live in a cold climate and it seemed lika a fun project. It has turned into a not so fun project, since the car no longer starts after the intake was off, CCV changed and everything put back together. When we were done, I sat down...

    Hey guys, I recently got the P1500 “ICV Stuck Open” code on my 325ci which would put the car into limp mode within 5 min of driving but no difference to performance (no hard starts, idle issues, reduced economy, etc.). As I was taking apart the intake system, I found the MAF sensors connector...

    Hi guys, I have a noise, somewhat like a shit blow off valve, coming from somewhere along my intake when I touch the throttle. It mostly noticeable if I just lightly tap throttle and it sounds like it’s coming from low on the engine, making me think it’s the idle control valve. I‘ve done a...

    Hello. I'm replacing my intake boots and thought it might be the best time to reroute my positive battery cable. (I routed it incorrectly and didn't have enough slack when I replaced the hard coolant pipes last year) Based on this picture, does anyone know how I can route it without removing...

    I’m not too sure what the cause is but it is seeming to get louder over time. The whistle noise is only present when my foot is on the accelerator and the rpm’s are around 2000-2500 im thinking its anything to do with the intake? any help? All inputs are appreciated

    Preface with I know that gains from a CAI will be minimal and I'm not going for big power or anything, just looking for a bit more pep. Intake sound is an added bonus too. That said, does anyone have any experience with these intakes for a 330 (non-zhp)? I have supporting mods like headers...

    Hi, I just finish swapping the N42 to an M54B25, It was running fine so I decided to take it for a drive. I did not have any air filters so I decided to use a piece of cloth hose clamped to where the MAF should be. When I came back from the 10-mile drive I noticed that the rag and hose clamp...

    i have an 03 325i m56 sulev. I dropped the engine and did some refreshing on it for the last month and ran into a problem with the intake manifold. I took it off and the two rubber seals fell out that hold the mounting hex nuts to the intake and i need to know if anyone knows where i can get...

    I will need to replace my air filter soon and instead of going the same $11 dollar OEM route. What are your thoughts on putting a K&N filter in the OEM intake box? Kinda like this, Custom Intake Using STOCK Airbox but probably without making the front inlet bigger. I am looking for some intake...

    Hey guys! Me again with another stupid question...Does anyone know where I can get a bigger intake manifold for a e46 2.5L coupe? I love my little bmw but I wish it just had a little more pep to its step, tanks!

    Hello. I have a problem with my e46 320ci. The car wont idle and it feels like it doesnt have any power at all. It also runs very rough when i press the throttle and the rpms jumps up and down. I diagnosed the car with an OBD scanner and it said it was a bad mass air flow sensor so i changed it...

    Hey guys, I have an '03 325it and I'm hearing a chirping type sound when I step on the gas. Sounds like the chirp is coming from around the intake/intake manifold but I can't locate it. Only chirps when I first hit the accelerator but constant acceleration will not cause any sound. The first...

    Hi all, Was just looking over the engine bay (no car problems that I can tell, runs nice!) but I’ve heard cracked intake boots are common so looked at mine while I was poking about. To me it looks pretty damn cracked. But like I said, no issues. Common to look like this or is it on its way out...

    Hello Everyone, I have a complex problem that I would love help narrowing down. Thank you in advance to any contributors. I don't drive my e46 often and so this problem has been dragging on for some time. I love this car and want to keep enjoying it. Last January I brought the car in to the...

    I have been trying to diagnose and remedy this problem for several months, and now I need the to call on the collective knowledge of the group. It all began when SES illuminated one morning as I was on my way to dealer for routine maintenance. The car was behaving normally on the roughly one...
