GROUP BUY - E9X M3 Carbon Intake Plenum
Group Buy Expiration Date: 28 February 2023 00:00 GMT

Hey everyone

Ive recently been looking at carbon plenum options and I came accross Carbon Klasse. Have a few friends who have their plenum and have nothing but good things to say.

I was able to get in touch with them and come up with a deal thanks to Carbon Klasse, im able to offer you a group buy for their carbon intake plenum for the E9X M3.

The full retail on these plenums is £1100 (1327.59 USD) + Shipping.

We have managed to agree a deal for a 15% discount for the next 10 units.

So a break down on cost. The initial cost to you would be £1100 (1327.59 USD) after you apply the discount code SLOWWM3 the price will drop to £935 (1128.45 USD)

Here is a product description direct from Carbon Klasse:

E9X M3 Carbon Fibre Plenum Conversion

Taking inspiration from the ultimate BMW M3 GTS & BMW M3 CRT Engine bay, we decided to keep things original and implement what we consider as OEM+.

Our plenums consist of replacing the top half of the OE Air Box with a full high temp carbon fibre version, ultimately increasing induction sound and cosmetically enhancing the look of your engine bay.

To get into the group buy you just have to apply Promo code : SLOWWM3 at checkout.

This is limited to 10 slots only.

Down below I have attached a few pictures of the different finishes you have when purchasing the plenum.

Options are;
Gloss or Matt finish
M power stickers and/or OE V8 badges
And you can either do OE design or Motorsport plenum

If you have any questions regarding the group buy feel free to dm on here or on IG @sloww_m3

Btw, the OE design is stated to be a “50% increase in sound”

The Motorsport design or smooth domed top says it’s a “75% sound increase”

I have one of the CK matte Motorsport plenums and it’s fantastic. I previously had a different carbon-lid plenum and the Carbon Klasse quality is miles ahead and sound is more pronounced than my old “export version” plenum.

I have a gloss domed top plenum and intake lid waiting to be installed. Can confirm that quality is great. Really pumped to get this on the car.

Any chance they'd offer a package with the airbox lid discounted too? I'm interested in both.

Also note the promo code isn't calculating properly:

At the moment all they’re doing is any order of £1100 or more is getting 15% off , so if you add the carbon air box lid to the plenum order it will deduct 15% off the whole amount

I am in. With the USD exchange rate it was ~$1700 for the plenum and an airbox lid with shipping to the California. I love the satin, but I already have a Dinan intake and struts, so went glossy motorsport style.

Thank you for the group buy.

Interesting one. Does anyone have any sound clips of either of the designs off-hand (without any other exhaust mods?)

This is the OEM style CK plenum with test pipes and standard everything else. Closest thing I could find.

I think that one's got a rear section plus test pipe, but still good info. Did some more digging, seems like this has an intake and airbox lid but otherwise claims all the noise is the plenum:

Hi,

I missed out on this, but if anyone ordered the Motorsport version, please can you post some video/sound clips? It would be great to hear how the motorsport version compares.

Thanks!
