K&N Performance OEM Replacement Air Filter (EFI)

OEM replacement performance air filter

Customer Reviews

    I put an Nfield EFI Silencer (Z91510) on my 2011 G5 Classic when I bought it in Dec., '10; never rode with the stock muffler. A couple months ago, these K&N filters for my bike were on sale so I bought one.
    I'm surprised, and very pleased, at the noticeable increase in power and acceleration after installing this filter. I suppose the muffler may have something to do with that as well, but, whatever, it works, and I'm a happy rider!!
