Review part SU-3590
Tuesday, September 09, 2014 - Part SU-3590
I find all of your filters as far as increased performance are far better than OEM filters. The only problem with the SU-3590 was the wing nut supplied with the filter was almost impossible to use without disassembling the whole air box, but with a 6mm all thread rod and a wing nut it was a snap to install. I use your products in all of my cars and motorcycles. Keep up the good work!
