Hi,

First off, I continue to have an absolute blast with my 2020 M340, whether on the highway, track or any of the Dragon drives.

Over time, I have replaced all of it except diffuser. I have looked across a number of sites, but have a challenge finding a gloss black diffuser for my M340

Would appreciate any help in locating

Thanks

It is hard to find a cheaper aftermarket diffuser fits on m340 but below 2 diffuser are for the m340.
2 fins vs 4 fins.

First and foremost, thanks for the information.

It figures, I liked the 4 fin one, but it's out of stock.

Certainly aren't many options!

Yes they only have 1 or 2 very low in stock and go out so fast.

I have the 4-fin one by ikon and it fits like a glove and looks spectacular

Looks awesome.

Do you have the power trunk? If so did you have to have it coded or anything and does the kick function still work?

[GD1981]

No power trunk for me so didnt have to worry about it.

Well, after an abortive attempt to get a gloss black diffuser from eBay, I was about to give up the ghost & have the OEM one painted.

Thankfully, I checked Kies Motorsports and found a good one with 4 vanes, albeit it matte black. I ordered it & it arrived 5 days later, nicely packed an complete with the small lip that goes bottom of tow hook hole. Took it down to body shop & had both pieces painted gloss black & installed -- looks great!

I've also attached a before and after picture

Looking great!

Is that 2 pcs or just 1 pc?

Mark729 ,

Thanks, I really do like the way it came out

I posted a before shot (with OEM Cerium gray diffuser) on top and an after shot (with gloss black painted Kiessport diffuser) on bottom of my previous post

Actually, threw pieces: large piece that goes across; piece with 4 fins that snaps into center of large one; and the small lip for the tow hook hole

Two quick questions. Do you mind sharing how much it cost to have it painted? Do the stock exhaust tips attach to the back side of the diffuser?

Thanks

I must say, and im form the UK, so tastes may vary wildly, but what the hell is a prestige car like an M340i doing with all those silly badges splattered over the rear end... it's spoiled a sleek classy car , it now looks like some cheap chav mobile.
Sort it out mate.

Ikon is telling me this diffuser doesnt fit our cars:

https://www.ebay.com/itm/Fits-19-21-...-127632-2357-0

I know someone above posted this as an option but has anyone actually bought this and fit it to their car?

I think that's the diffuser folks have been buying for their 340s. Strange thing for the seller to say as the car in the photo is a M340.

I dont get it. It does say the seller will pay for return shipping. Might be worth a shot to buy it and test fit it.

It does look like it's cut to fit our bumpers.

Anyone know if the Kies diffuser can be installed without having to remove the rear bumper?

That looks great, but can you confirm that's what they call "matte black"? That's where that link takes me. I wanted gloss and that sure looks glossy to me in your pic!

[RSnic]

TheCrespiEffect ,

Thanks

In fact, it did come to me in matte black (no gloss); I had it painted gloss black-- and that's what in the picture

Hope that help
