What you can do to your RDX: Engine Upgrade Master List

Here is a running list of engine mods that can be done safely to your 07-12 RDX. (sticky please)
I'll try to keep the list updated with the help of others, anything that might be incorrect or missing will be updated with your help. I'm not an expert, I'm just trying to put together the puzzle.
Hondata Combo - Potential HP gain is K&N: 54.77-64.77 and CP-E: 65-75
Non-Hondata Combo - Potential HP gain is KN:104.77 and CP-E:115

The BOV helps as well. Pure Tuning - Aaron, stated he's seen he same BOV in Subarus (same part) with eventual, inefficient performance. I'm currently using the "light" spring.

That air straightener is definitely interesting. I've got a stage 2 Legacy GT and there's certain intakes to avoid because of turbulence across the MAF (Subaru in general). I'll definitely have to look into it and ask my tuner about it.
