MHC+ Carbon Fibre Twin Fin Front Ducts for the BMW G80 G81 M3 & G82 G83 M4 were designed to transform the vehicle's front end, especially when combined with the MHC+ SP1 Front Splitter In Pre Preg Carbon Fibre.

The aggressive twin-fin design matches up with the SP1's duct lines for the ultimate G8X front-end transformation. Whilst the MHC+ twin fin ducts work great with the SP1 front lip, they are also great as a stand-alone front-end upgrade for a more aggressive and imposing look. The MHC+ twin fins are a direct replacement for the factory honeycomb grilles and are super easy to install - see our detailed installation guide below.

Why choose pre-preg carbon fibre?

Unlike normal carbon fibre, pre-preg carbon is reinforced for increased strength and durability. It can also be an astonishing 70% lighter than other carbon options, ideal for weight-saving. Quality-wise, pre-preg carbon is far more consistent meaning the chance of imperfections is dramatically reduced. The manufacturing process eliminates undesirable air bubbles and results in a perfect, sleek, smooth & high gloss finish, making the ultimate part to complement your vehicle. 

When you buy pre-preg, you are investing in a higher quality, longer-lasting part that will outlast other forms of carbon fibre and potentially save you money in the long term.

Better pricing than BestBuy’s Geek Squad extended warranty!
Asurion is on of the best extended warranty put there! bar none! I used to buy only from BestBuy because of their Geek Squad extended warranty. But it’s way more expensive compared to Asurion. although with Asurion they require so much paper work and pictures first.

They refunded the amount. We just had to send it to them 2 times before they did.
We bought a printer and it was having issues from the beginning. We thought at first it had to do with the WIFI, so we didn't say anything, but then more things were going wrong. I talked to the manufacturer, who said it needed to be replaced but we had to go through Asurion. Asurion "fixed" it and sent it back but we had our doubts. Sure enough, it was within the same month we were sending it in again. This time they just gave us an amazon gift card for the entire amount we had paid. Thankful for the warranty. They ultimately did the right thing, I just wish we could have gotten it done faster.

Asurion worked as intended.
After three years, my monitor failed. Asurion paid to send it to a repair center. I didn't save the box the monitor came in, and paid $23 to have it packaged up. They kept me informed of the various steps, such as en route, arrived, testing, and repair started. They discovered it could not economically be repaired and refunded my purchase price. The entire process from me telling them it was broken until the refund took 5 days. I am well satisfied with the service.
