Don't really serve the RSM purpose actually, unless VAFC kaa, maybe good for tuning purpose. RSM most likely to eliminate speed-cut (180 kmh) on JDM vehicle. Donno whether Wise got speed limiter or not!
I'll comment about this specifically for Airtreks or Evos. I've been using K&N drop in since I got the Airtrek 5 years ago. Never tried open pod before, and now itchy handed.
