Turner Motorsport CSL Airbox

[jk715]

Few notes from my install:

1. SMG relocation is a tight fit. Needed to drill a hole into the strut tower with small room for error.
2. Strut tower brace barely fits. I'm hesitant to put on the brace because it will definitely rub. Update: Make sure the bottom bolts are seated all the way on the bracket. I had to push down with tightening.
3. Attach both lower connections prior to securing to throttle body.
4. Remove driver side fan shroud, it will rub.
5. Turner bottom harness bracket needs to be bent another ~5mm.
6. Throttle body gaskets need to be from pre-'03. Update: Aftermarket boot clamps need to be secured in the right angle to not interfere with the actuators/rod.

2. Strut tower brace barely fits. I'm hesitant to put on the brace because it will definitely rub. A few spacers on each end would work.

Hmm that doesn't sound right. Are you sure your airbox is fully seated everywhere?

I've actually had better results attaching everything on the bottom after the airbox is secured to the throttle bodies. However, there is a specific order in which you should do this or else you will have a ton of issues. First crankcase breather valve hose, then ICV hose, then the two 10mm nuts that hold the airbox, and finally the rubber mount that slides onto the metal bracket on the airbox.

Aftermarket strut tower? Two connectors/bolts on the bottom of the airbox seated all the way?
SMG relocation is kinda tricky. Measure 10X, drill once.

Which one is that? #10? https://www.realoem.com/bmw/enUS/sho...diagId=11_3517

I’ll take a look tomorrow. Need to strip it apart to replace the tps sensor.

I didn't drill into my car, I used an existing hole and mounted the bracket in a likely non-traditional way. Either way, seemed to work fine and the reservoir never moved.

Anyone know what size bolt is needed for the smg reservoir bracket? Picture for reference.

That's mine. It was just a random one off of my parts car with a 10mm nut on it.


Here's how it turned out:

Here's how it turned out:

I see that basically everyone with the PCV valve/solenoid left it in place and lengthened their breather to make it longer.
I went overboard thinking the hole in air rail would cause a vacuum leak because the PCV would default open so I bought a pre-04(?) air rail. In the meantime I have a vacuum cap/black fuel hose and a hose clamp blocking that hole I created on the air rail.
I should have simply lengthened my Breather, less $. Sucks to have bought an air rail and its not even a CSL unit.

At least yours looks a lot cleaner than the mess I have on the top of mine.

Regarding PCV solenoid, I also capped at the rail and removed it.

COVID-19 Ended up being the rear bottom screw wasn't fully seated in the bracket. Had to push down and tighten at the same time. Maybe the silicon throttle boots are bigger/stiffer? Strut tower brace now has about 5mm clearance, hoping this is enough and doesn't scratch up the box.

Yup, #10. you'll see when you get it but the existing bends are not enough clearance for the harness. Should bend easily.

Received my GB bought intake yesterday and sadly it was damaged too. Will contact Turner tomorrow, thanks for all the useful info.

lol jesus, I feel like I'm the only person so far to have received theirs intact..

Dang, I’ve lost count.

Yeah, awful packaging plus no fragile warning for a deceivingly lightweight package. The JB Plastic Bonder is supposed work for bonding metal to composites - https://www.amazon.com/J-B-Weld-5013...01IBOK7FE?th=1

[Will ZCPM3]

This is not surprising. Everything I've ever ordered from ECS or Turner has been horribly packaged.
