Dont bother . stick to your good old standard air box with a bit of moddification . take off the lid ,remove the filter and you will see a trumpet shaped piece of plastic sat in the bottom, simply take it out this leaves a nice size hole for xtra air to get in ,replace the standard filter element with a performance one replace lid and take it out for a spin, while driving normally you wont tell the diffrence but when you put your toe down youll hear some nice suttle induction noise.. give it a try after all it is a free mod..
