I'm just wondering if it's even worth it I just bought the Afe stage2 sealed box 2 months ago for my E90, to spend another 400$ when I already have an intake is difficult. What do you guys think what are the benefits over the Afe stage 2 vs euro. The Afe has dyno proven results for the gains and the euro intake i researched the gains are mostly at lower rpm range compared to higher rpm range for Afe stage 2
