Thanks for the question, which is a fair one. The S&B intake mimics the stock one, which draws from both behind the grill and the left fender. I didn’t realize this before I bought it. Fortunately, I don’t have to do too many water crossings, but I’ve been thinking about seeing how the truck reacts if I only draw from the fender. There’s always the one supplier for a snorkel intake which should increase airflow via the fender as well, but I’m not a huge fan of how it looks...Where is that new intake pulling air from? It looks like it's pulling air from the grille area. That could be really bad if you go through and moderately deep puddles. Eeek!
