Unintended positive side-effect of K&N drop in
I have a Roush axle-back on my 2013 V6. Often between gears when I push the clutch, there would be this loud pop sound. I installed the K&N drop in today and noticed there was no more popping. All the way home from work I was trying hard to get it to pop, and I only got it to do it once, and even that was barely noticable. Before the K&N, it was very loud and pretty annoying.
I just went for another drive down the street and no popping. I have no idea why the filter would effect this, but I'm so glad I got the K&N for this reason alone. So if anyone else has this setup with the popping problem, try the K&N, maybe it will have the same effect for you. I'm going to keep testing throughout the week, but so far so good!
