- Pros: Easy to install, no need to replace
"Was pleased with the easy install of this filter. Be aware you'll need to purchase oil to clean it in the future. It does come pre-oiled though so you don't need it right away."

- Pros: Added Power, Nice feeling
"This was first time to purchase K&N Filter for me. Until now, two weeks later, I'm pretty satisfied with the performance. I don't know how it is durable and reliable but I can feel more power and a little bit different engine sound. Good for the money!"
