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!

It was very easy to install and fits and looks great.

Does not for the car - filter looks defective - I emailed asking for a return label and a refund and I am waiting to hear back.

I'm thrilled with the increased power! It really woke up my 2021 330i, and using the 93 octane map provides a significant boost while still feeling smooth for daily driving. The Tuning Pro app is simple to use and makes it very easy to switch maps or configure the warmup timer for added engine protection.

High quality products for your high end vehicle. Great customer service!

Took a while to get someone to call me back, but thankfully they coordinated with one another after calling back and mentioning this, and they immediately got back with me and walked me through all my concerns and skepticism.
