Just wanted to post a bit of information for any of you that have been having negative LTFT issues. I purchased a CAI 2 months ago shortly after buying my 2002 330ci. Since then, I have been dealing with P0172 and P0175 error codes. After weeks of trying to trace down potential causes, like MAF...

Hey guys, I am pretty new to CAI mods even though in some situations it is considered a pretty standard/beginner mod. Anyway my question is what would be a nice budget friendly cold air intake. I know it doesn't really show any exponential values of performance, but I do love the throatier sound...

Okay friends I recently found DIY's for both a heat shield and a cold air intake and I plan to do both. However, I have a question. I drive a 325 so my MAF is 2.5" diameter. Would reducing UP from the 2.5" MAF to 3" intake tube cause me much trouble? too much air flow? Wobbling? damage to the...

Searched around on the forum and couldn't find any info on this... I'm thinking about making my own custom CAI through bits and pieces I can buy at the local auto store and I can't decide on which air filter to go with. I want to stick with the non-oiled filters because of the horror stories of...

Pretty new to this DIY forum. But I recently purchased a used Dinan CAI and I know I am missing some parts. Called the local Dinan authorized shop and said that i'd have to figure out which parts I am missing and to order from headquarters. The problem is, I am not sure which parts I am...

so I recently installed a long, dinan cai intake, and the cut a portion of the brake duct per their instructions. Just curious, will this have any effect of my car whatsoever? I know the brakes need some airflow, but any harm in doing this?

How much should it cost to get the Dinan high flow intake system installed, by a professional? Also how hard is it to put it in, as the instructions look very technical. Thanks guys!

Hi I am looking for a dinan high flow intake system. I would prefer to have the system new, but a slightly used system is ok as well. I need it to fit a 2001 BMW 330Ci. Also if anyone knows where I can, get one for a discount price that would be extremely helpful as well. Thanks and I hope to...

Hello I own a BMW 330Ci, and I was wondering what the best cold air intake I should buy for my car is. I have heard of brands such as Dinan, ECIS, GruppeM, and Rouge, I just dont know what intake is the best out of these ones. Also I would like to know if it is even worth putting in a cold air...

Hello I own a 2001 BMW 330Ci, and I was looking on the Dinan website at their cold air intake, which goes with this model. I was also looking at the K&N 57-1001 CAI which goes with my car. I did some research and people have been saying that the K&N CAI is no good, and will actually make me lose...

so i found an amazing deal for a a dinan intake (old style metal tube) but it is for a 328,325,323. I searched and found out that the tube is 2.5" and mine is a 3". so all i would have to do is get a rubber coupling. Can anybody reassure me that I am correct. I dont want to buy it and it not...

Has anyone ever had a problem with the AFE intake for the 330 causing a Service Engine Soon light? I had a Conforti Intake that I just returned because I kept getting a SES light and am looking to the AFE intake to hopefully solve this problem for me. Thanks for any help!

Does the Dinan Air Intake block the brake cooling duct? Does it obstruct it in any way? If not, then how does it get air from the brake duct? Thanks!!!

Hi guys, I understand from ESS website and from Safar, that the new ESS twinscrew supercharger kit does not have an alternative CAI. I understand that non supercharged cars gain a few HP by replacing the BMW CAI with other, better flowing CAIs. I was wondering if the same is true for the ESS...
