you wont lose power there, is like the different for replacement panel filter and an IK kit is that IK kit will improve your power in high rev. As for replacement panel filter will improve your low to mid range power. Coz I tried both replacement filter and pipercross on my 172, with the replacement filter, the low to mid range response better than the pipercross..... but since i like the sound of pipercross, so I keep using the pipercross now...
So if u like to have more torque feeling from low to mid, go for replacement panel filter, if u like the sound and want more power at high rev, go for pipercross....
