Looking to purchasing dinan intake with the BF sale. Should i also purchase the dinan inlet?

[VegasG42]

Just an FYI - the inlet does very little to increase sound and performance.

However, it does increase the difficulty and time for the installation.

Agree with VegasG42

Last summer I installed the MST intake and turbo inlet and ran that for a little over a year. I recently removed the MST inlet because I do not like/trust the fitment and attachment system (just a silicone tube + clamp). I've now been running the MST intake with the stock turbo inlet for a few months and do not hear any difference - it still makes the exact same noises as when I had the MST turbo inlet.

The aftermarket inlets may provide an air flow benefit, but if you are looking only for sound, don't waste your money. The only argument I have for the Dinan CF inlet is it will likely last longer than the OEM plastic inlet, so if you plan to keep the car for a long time, it would be one less plastic part to break down over time and require replacement.

Regarding the install:

• Intake - Super easy
• Turbo inlet - The first time it is annoying to do. Removing the metal clip that attaches the factory inlet to the turbo (Dinan re-uses this) can be annoying and dealing with the PCV tube that attaches to the inlet is a pain to remove (you can find many threads on this). The juice is not worth the squeeze. Since I've now installed/removed the inlet 3-4 times, I can remove the metal clip pretty quickly, but the PCV is a headache every time. The primary problem is you have very very little area to work.

The inlet isn't worth the headache.

I've seen a lot of praise for the Dinan intake but after buying one I just don't think it's a high quality product. The way the lid is held on with these cheap plastic pins basically guarantees that you will lose half of them if you ever want access to the filter, and guess what, they provide you with a bag of extras so they know that as well. I guess you could put a piece of tape over each one when you pull the lid off but again, stupid design. The fitment was ok but not top notch as the reviews would indicate. I also wasn't a fan of getting a giant box of packing peanuts and no installation instructions (it is fairly straightforward but a reference helps). I actually pulled up the BMS ones to install the Dinan intake. It still functions fine and it does look good, but there are other options.

If I did it over again, I'd go with the BMS competition or MST intake. I think the MST is about the same price and the BMS is $380 so you'd save money too.

Drop in filter, muffler delete.

If you're gonna do an actual aftermarket intake at lease make it cold air, like the RKtunes one

I'm very happy with my BMS Competition CAI. I've had it for a few months now. Great quality, great fitment, easy install. Modest increase in sound. Re-uses the factory heat shield.

The inlet was an absolute nightmare to install. Legit 0 room to pull off the plug and the clamp which gives you constant worry it’s going to break. Looks super cool until reality sets in and you realize you can’t see it. The intake fit with the inlet perfectly, I got rid of the bulky one, and I learned that it was a pain in the ass to change out. I’d prolly do it again unless the price was higher. Price was already ehh for what it is so any higher 100% no.

[BlueLEDz]

In stark contrast, installing the inlet in the 230i was fairly straightforward. Plus with the smaller engine, the inlet is very visible.

Where best place to order MST for the m240i?

R44 has one but the shipping is $$$$$

I ordered from xtreme power house, it ended up getting shipped from kies motorsports, try either one of them shops.

[IanH]

R44 is in the UK, so you can look at products there but it wil never be the best source per-se.

[MPR]

If you’re looking to save a few bucks then you can try an off brand that looks identical to the MST. You may end up getting a better fitting intake that sounds just as good.

The MST fitment is terrible, I considered buying a Dinan or BMS since they fit like OEM (from what I’ve seen & read). When installing the MST I thought I was shipped an intake pipe for a different car but it ended just being the way it fits. You need to angle the pipe into the heatshield box and then kind of slip the filter mounting silicone over the pipe and through the heat shield opening.

Yeah, it's crazy the way the filter barely fits on the intake tube through the hole.

I can't believe the kit sells for nearly $500.

It does sound great though

If that's the case, OP should definitely get the BMS and call it a day.

I'd just get it from the source, burgertuning.

If its sound that hes after, the question is which sounds better/louder, and does carbon fiber matter.

I have never heard the Dinan or BMS and was in this same position deciding between the two when I was looking to replace my MST.

[IanH]

Why buy a new box to replace the stock box? Dinan and burger aren't sealed, so you are dropping a true cold air intake for one that isn't cold air but also doesn't have as much sound?

C'mon folks...

Either go open filter, eventuri or rktunes, or just take the $80 option.

I've been very honest about the BMS from day one.

Being that its a much more enclosed, mostly sealed airbox, the turbo and intake noises are reduced a fair amount.

If I had to put a number on it, I would say the BMS is a good 30% quieter than the MST. Don't let anyone tell you the BMS is nearly as loud as the MST. Because you will end up disappointed. I remember going for my first test drive with the newly installed MST - I was grinning ear to ear.

But the BMS is providing cooler temperatures when I need it the most during the summer time here in Vegas. So for me it was a trade off - better reliability, better fitment, cooler temperatures. But less sound

The stock box is sealed. The Dinan and Burger are sealed as well.
Something like the MST is more open and will draw in more hot air.
I don't think the stock box, Dinan or BMS would be considered cold-air intakes.

They are considered 'cold air' intakes due to the ducting tube that let's fresh air from the front bumper/grill area that leads directly into the sealed air box. And the air box keeps the warm engine air from being sucked directly into the intake filter.

With something like the MST, you're getting a bit of both. Fresh air from the front , and some engine air being sucked in. But you get all the noise. People with the MST style intakes mention a bit more heat soak occurring when doing multiple runs at a 1/4 mile track, for example.

[IanH]

The dinan and burger both have open holes/slats on the side of the box into the engine bay. Neither is sealed.

Only stock, eventuri and rktunes are actually cold air intakes. Maybe injen evo is actual cold air too?

Stock is a true cold air intake, it only draws air from outside the engine bay. With a drop in filter you get all of the airflow from these other options. For a fraction of the price. Every tuner says that stock turbo all that's needed is the high flow filter, the other intakes provide no benefit.

Like I said, if you wanna suck engine bay air you can, and you will get more sound and you do it for that reason, but if you're going to choose that go full open air.

[VegasG42]

The carbon fiber Dinan can be had for about $460 right now. The regular black - $360.

The BMS has been $360-ish for a while.

The Dinan Carbon fiber intake looks so good.

My selling point of the BMS over the Dinan was the factory heat shield is maintained. If you've ever reached your hand into the engine bay after driving to tinker with something, you will feel how everything in that area is very hot. (obviously)

But isn't the stock box pulling in air behind the active grille? And if the grille is closed, it's not really pulling in fresh air? Or is the duct pulling in air below the grille in the lower bumper area?
I think it's pulling in engine air because it could be 70F outside and the IAT is reading 110-120F while cruising.
