The best carbon parts on the market!High quality, perfect fitting !!

Great Service and product. items were received as described. Quality is exceptional! Ana and the Owner are extremely kind and helpful to my purchase. Items were very well packaged. Very happy with my purchase~Installation was pretty straightforward in my case since i have installed with another CSL rep, so wiring is all the same. Fitment is really good.. would recommend to ppl who are looking for CSL type bootlid to buy from Karbonius~

The Karbonius Airbox completed my M3 Sedan build. Beautiful and sounds incredible.

Ana and the folks at Karbonius, like their products, are THE STANDARD! Amazing individuals who produce amazing products and offer amazing customer service. This is now my 3rd time ordering/dealing with them direct and I encourage you to do the same. A+++

An absolute pleasure to deal with. They make great products and stand behind them. They went above and beyond in helping me out with an issue I had on one of their earliest airboxes, and I wasn't even the original purchaser of the box so they had no obligation to help yet they still did. i highly recommend them and will definitely be purchasing some more CSL goodies from them down the line.

Top class. I ordered CSL intake and quality was way beyond my expectations

They are absolutely brilliant! The quality of their products is exceptional and one of the best after-sales services I’ve ever had. 100% recommend!

What can I say? Super professional, timely and superior products. The cabin filter cover is lovely and the vented engine cover is amazing. Super light and just top quality.I'll pay a visit in person whenever I take a trip to Spain. Keep up the good work and thank you Karbonius team!

Karbonius is an incredible company that makes incredible products. The CSL Airbox and snorkel I purchased for my E46 M3 are of masterpiece quality. There is clearly an extremely high attention to detail on the design, fit, and finish of these products.I somehow lost some hardware from my airbox and Karbonius made for a very fast and easy replacement! This was completely my fault but the Karbonius customer service was fantastic. They clearly care about their customers and have passion for the product.I have had my components for several years now and they have had zero faults, even with track use and some other abuse to the parts.I can genuinely not recommend Karbonius enough! Their parts don't come cheap, but know you are getting what you pay for, and at a great value. I look forward to doing more business with this company.
