Probably getting ahead of myself here since the car has other problems, but right now my Blacktop has a cheap autozone spectre intake. Around 2-3k rpms, it sounds quite bad. I am looking into installing the 100mm trumpets. How hard is this to do? Can I just take the autozone intake off and bolt the trumpets on? Do I have to mess with the fuel system? Is there a write up or video on how to do it, I can't find anything except stuff like thiswhich doesn't show the install of the trumpets from before unfortunately.
