The tune is amazing. Definitely feel a difference in power and acceleration! Want to commend CarBahn for customer service too! Josh W

Great product, and excellent customer service!

fast service, great product.

Shipping of this item was fast. Item was well packaged. The quality of the carbon fiber is high quality and it fit like a factory part.

Fast shipment

I love these, the provide improved stability for my G80 M3, I highly recommend. . .

Beautiful.

The part your system suggested did not fit correctly I returned it for a refund. It cost me $80 to return.

Great fit and finish. Easy install.

The CarBahn air filters are simply the best…none better!

Fast shipping and delivery!!

Shipping took 6 days for $10. Ensure this expectation is displayed well before checkout. I was not aware of 6 day shipping until after order was placed.

Great Product! Looks fantastic

Very light and looks very sturdy. Customer service is great, rec'd the item with huge hole in the box, took pictures and sent them to Carbahn, without issue sent me another, unbelievable!

Great service ! Promptly shipped! The product is a must have for any G90 owner to protect the radiator from damage !

Great quality and fit perfectly

Thank you

Perfect fit and easy install but the screws provided were incorrect (over 1” long). Get your own 1/2” or less self tapping screws or you’ll drill into the rocker panel. I reached out to support about this and got no response after a week.

4 bolts for $46? Wild. I asked the website AI/help how many bolts were included before I purchased and it said 12. But I received 4. I coulda ordered a 6 pack on amazon for $12. Yall got me, what can I say. An honest company would either lower the price or increase the number of bolts included. $10+ per bolt is crazy.

Love this controller and the fact you can buy a replacement car warranty through Carbahn. I’ve only been able to use it up to 93 octane but even at 91 it is a noticeable difference. Waiting for their e85 kit to come out!
