Using four of these angled pods on the 89 kawasaki zx600. Filters are the perfect size and the angle allows me to keep the filters clear of any frame contact, pure fresh air baby! It runs very true to the advertised i.d. and the clamps are top notch, the fit is firm and reliable. Shipping was fast and each pod came with a pair of UNI decals to boot. Would recommend to anyone looking for top-notch filtering when going with an airbox delete.
