I, as many others on this forum use a replacement filter (Either Green, K&N etc) along with replacement air ducting - which you attach to the initial 90 degree bend bolted to the slam panel, straight into the standard airbox.
This has been fine for me, and noticed a very slight difference - mainly lower down the revs.
Hope this helps

Cheers jimbo so a replacent element with a better air flow duct will be just as good as a cda or streamline kit
