i just did mine less than a week ago in conjunction with an AEM intake. It took ten minutes to do. Remove top 2 bolts that hold on engine cover, use hex head wrench to remove four screw. I left the screen in (it is only actually covering about 1/3 of the opening.). Hardest part was putting in new bolts and aligining the things back up. I kept thinking I was putting the new bolts in crooked. Otherwise it would only take 5 minutes. No cables removed in process. Be ready for the whistle... sounds like someone letting air out of a tirein the 1600-2200 rpm range.
