I hate my (now defunct) dbilas with a passion. It hooted, it was heavy, the side-bolt that held it to the engine sheared on two occasions, the panel filter was tiny resulting in power loss and the MAF section is the wrong size.
I replaced it with the ITG filter and all my missing horses came back. Just get the ITG or forge intakes, and I understand the EVOMs has a pleasant noise as well. Or a BSH TruSeal. Or anything, in fact, apart from the dbilas.
