2019-2022 BMW G20 3 Series Performance Inspired Rear Diffuser
IMPORTANT NOTE FOR CUSTOMERS TRYING TO REPLACE 330 DIFFUSER WITH M340 STYLE: You will need to purchase OEM PART # 51128079607 (rear bracket) as well as the angular exhaust tips in order for the installation to be successful. It is NOT a direct replacement.
Introducing the BMW G20 3 series performance inspired rear diffuser upgrade for your 2019+ G20 BMW 3 series sedans. This diffuser is made from mold injected thermoplastics and will fit any M Sport equipped G20 BMW 3 series (both petrol and diesel versions). That includes the 330i, 330e, along with the diesel variants. This will fit M340i models as well since those are M Sport equipped right out of the factory.
This does NOT fit the standard bumper, you MUST have a factory M Sport package or aftermarket M Sport conversion for this lip to fit properly.
Note: The M Performance style rear diffusers are a matte black finish. Both can be installed as-is, or can be repainted if you so choose to.
If you do not know which trim you have, please refer to this image below to see the difference between the non M Sport trim vs the M Sport trim:
Disclaimer: Although these kits can be installed on your own (DIY) we highly recommend that you utilize an experienced body shop to perform the labor. A professional body shop can be the difference maker between a good or bad result.
As best practice when looking for a shop, you should ask to see results of their previous work. If they claim to be experienced but have no tangible evidence, we would recommend caution when taking your business there. Kiesmotorsports is NOT responsible for poor labor practices.
If you have any questions or concerns, please don't hesitate to contact us. An informed / educated customer is a happy customer.
Your satisfaction is our priority, and we look forward to serving you!
We are typically very quick and have a 24-48 hour turnaround time (this applies to products we have readily available at the warehouse and not a product that requires special order). Transit time depends on your order and which warehouse we are shipping from, but typical transit times are between 5-7 business days from one side of the US to the other. Larger items like bumpers and body kit conversions can take up to 10 business days to get you from time of ship.
Majority of the items we offer do ship free to the lower contiguous 48 states. States that require plane or boat to reach (such as Hawaii, Alaska, Puerto Rico, etc) do NOT qualify for free shipping. Larger items such as bumpers, hoods, fenders, also do NOT qualify for free shipping. Please contact us to inquire about international shipping costs. During checkout, you will know which items ship free and which have shipping costs associated with them. In general, larger/heavier items will have additional shipping costs (body kits, wheels/rims, etc)
Even though everything can be shipped internationally, sometimes the cost is simply just too high and doesn't make sense to do so. We're here to make sure you have a great shopping experience, so if you have a product(s) you want to inquire about, please contact us at email@example.com
Yes, we do price match reputable competitors in the marketplace. If you find a product cheaper elsewhere, please email us the (1) link of the product from our website and (2) the link to the competitor site. We will make an assessment on our end if we are able to price match or not and respond to you via email.
Typically you have 14 days to return a product you purchase when you change your mind. Damaged and improperly installed products are NOT eligible for returns. Shipping fees may be assessed and not refunded based on criteria as well as restocking fees. Please see our FAQ page for more details.
