Revainrating 5 out of 5

Huge improvement in throttle response

After installation, which was very easy with basic tools, I took it out and immediately noticed a difference. Actually, you could hear the breakthrough breathing much better and gulping down the air. I haven't mapped the bike yet, but I can only imagine how much more power it will be capable of when it all comes together. Buy this air filter. Looks just as great. Lots of comments and questions about road traffic from young and old

Pros
  • High marks for support and durability from testers
Cons
  • poorly thought out
