KNS Performance LLC

I highly recommend KNS Performance in Elmsford. He replaced my serpentine belt, tensioner, pulley, spark plugs (gapped to 0.026”), and ignition coils on my 2017 Focus ST— all at a very fair price. The work was done professionally and with great attention to detail. My car is running noticeably smoother, and I truly appreciate the honesty and quality of service. If you’re looking for reliable, knowledgeable automotive work, KNS Performance is the place to go! Will definitely be bringing my car back for any work that needs to be done.

Top tier work and customer service!! I needed help getting a underboost code diagnosed. He was able to give me a diagnosis for my turbo really quick and gave me several suggestions on how to proceed. I ended up bringing in a aftermarket turbo and he installed it for me. I forgot to order gaskets with my turbo and he was able to acquire gaskets in a reasonable time. Quality work. My car drives amazing now and the turbo sounds awesome!

5 stars for sure. Excellent place to take your car to have aftermarket work done on it. A few months ago I had my 2024 Mustang GT Premium lowered with Eibach Sportline Lowering Springs and Kevin did it wonderfully. Again I went back to him for a resonator delete and had a Roush H-Pipe installed and he did an amazing job. Only downside is the location, as the other reviewer stated, is right by a busy intersection next to a highway so sometimes its difficult getting into and out of the shop itself. Kevin has been doing this for a long time, knows what he’s doing and on top of that has a fast response time to inquiries - I will definitely be working with him more in the future. Highly recommend.

I brought a 2013 Ram 1500 Sport which needed a a complete brake system, water pump and a complete suspension system. Kevin was excellent in installing everything. He also installed a lot of modifications to the truck, bed cover, running boards, front headlights, rear lights and side mirrors.

I came here after looking at reviews for my Civic. I immediately ran into Kev, and he advised me of how much for installation of certain aftermarket parts and cost of work, he is very reasonable on his prices and definitely knows what he’s doing. Im going to be doing more business with the him in the near future because of the expediency and attention to detail of his work. I’d say the only thing bad about his place is the location which is right off of a busy traffic intersection so there is constant traffic trying to get out but it is still manageable if you’re looking for premium automotive maintenance & tuning at a fair price! You really cant go wrong here.
