## Customer Reviews

### ⭐⭐⭐⭐⭐ I fits perfectly!
*by J***N on August 3, 2024*

I installed this Reusable K&N filter on my 2003 Buell xb9r Firebolt. The installation only took 10 minutes with basic and tools, and fit perfectly! Definitely worth the money. The bike performed a lot better. Definitely a quality part.

### ⭐⭐⭐⭐⭐ High quality filter
*by R***T on October 5, 2024*

Perfect fit and great quality. I highly recommend this filter.

### ⭐⭐⭐⭐ Fits. Works.
*by I***S on June 27, 2017*

Fits like OEM. Filters intake air. Not much more to say here. Glad someone is making this part for our special unicorn bikes.
