The Dinan high flow cold air intake has been something I was skeptical of buying due to little to no reviews on the item; however I bit the bullet and installed it and let me just say there is noise to the cold air intake, there is minor performance and it sits nice in the engine bay. Went the dinan route due to gtr e46 vented hood and my god is it worth the money; due be warned gas consumption does go through the rough as you’ll just want to floor it everywhere you go especially paired with a stage 2 tune.
