Help: Cold air intake install

For those who have have a cold air intake (Dinan or custom) setup, how is your passenger side pipe setup?

I'm installing a set of Rezahyde CF intake tubes and I have completed the driver side, but am stumped on the passenger side. I have all the plastics removed (air box, snorkle, any unecessary parts) but there is a large metal heat shield that holds together the secondary air pump as well as part of the A/C (and a few lines).

I ran out of time (and sunlight) so for now I threw the stock airbox back on. I'd like some insight as to how to relocate these parts to make room for the intake.

Thanks!

SAI pump must be mounted upside down in the bracket. Bracket also takes minor modification to get it to bolt back up at the right angle.

On Bank1 (passenger side) the body metal must be cut below the headlight bucket. It's a minor cut that is actually necessary to fit the Dinan intakes. Same goes for the Raza CF replica intakes.

Just hope that that inverting the SAP doesn't start producing a nice squeal for you. I have an annoying noise coming from my pump after installing the dinan CAI. Before installation, it never made any noise. Now for the first minute or so, it sounds like I have a belt slipping on my car due to the SAP.

There is a copy of installation instruction for the Dinan CAI on the board somewhere. Do a search for Dinan CAI, it should be pretty apparent on the bracket and repositioning of the SAP with that.

It will also provide a cut out template for the cut that needs to be made as mentioned above.

That's because inverting the pump, as is required, turns it into a water pump. Replace the pump and your noise will be gone. Or just deal with it for about 80 seconds on cold start LOL.

They are bottom sucking moisture pumps from the factory, but turning them upside down makes the situation worse.



There isn't much required for the cut. Pull the bumper and remove the bank1 intake setup. Loosely install the CF rep piece, and cut a half circle with an air saw where you see fit. Finish off the area with a air grinder and fit the rest of the setup.

Could someone please post some pics of the portion that needs to be cutout to install the CAI and a picture that shows the area with the cutout?

Thanks in advance.


Also could someone please show the way to extend the bracket to allow the SAP to remain right side up?

Thats the air pump... The Dinan relocation uses a slightly different bracket, and inverts the pump upside down. You can use the stock bracket with a little ingenuity. The pump MUST be relocated upside down, and mounted so the line to the check valve is routed appropriately.

Do you have a picture of this setup?

You can, but you would need the software to do so. Otherwise you'll have a check engine light for inadequate secondary air flow.

And once you do that, you won't be able to complete readiness monitoring for OBDII/State Inspection testing. And of course, no Tuner will take the responsibility of erasing the codes, and still satisfying the readiness monitors.

Ahh the joys of BMW tuning... BOO.

Has anyone been able to install the SAP below its original location but keep it right side up?

With the people complaining about it making noise after turning it upside down, I figured try to keep it right side up. It's more the noise I'm concerned about. I figured the pump works fine either way......

BTW, is the noise a sign of faulty pump or not? And does everyone's pump make a noise after turning it upside down or are there only a lucky few?

All secondary pumps make noise, there are none that make zero noise (unless they aren't working). I turned mine upside down after 87k miles, and it made the same noise as when it was mounted upright. The first 2 minutes of starting your car from cold, step outside and stand near the passenger side front corner and you'll hear it working.

Almost done with mine. Just waiting for my heatshields to come in along with the SAP brackets. I've cut the plate to make room for the passenger side CF tube. Unfortunately I've also had to cut off a part of the headlight mounting point, also to make room for the passenger side CF tube. Oh well.... I hope the other 3 will hold the headlight in position.
Also, I think I'm gonna try to modify the OEM SAP brackets since I'm getting too impatient to wait for the Dinan brackets. My ECU just came it today so I'm dying to get the car back on the road.

3 weeks down time is a long wait!
