I took some advise around here and removed my engine covers last week. Took off all of the plastic pieces (4 total including the fancy center piece).
I've had my IS350 for 1.5 years and I drive it hard.
I am experiencing an very noticeable increase in performance all around. The IS350 is MUCH snappier at all acceleration, feels like a new car. It really didn’t seem to get much louder.
I would probably associate it with the air intake. In fact when I took that piece off and saw the air intake there, I knew there would be a difference.
To add to the change. This summer has been real cool until this week where we have had 2 90 degree days. I've been experiencing this increase in performance driving the car with AC on full on a 90 degree day.
I have no numbers and such, but the car feels a hell of a lot better, especially in simple mid range acceleration, driving on the freeway and stomping it. Feeling a lot like my old Sti's acceleration. While I haven’t hit the track in a few years, I did put a lot of hours in at PIR on the track and in AutoX in my S2000's and such so Im no dummy on car perf at 95%.
Thing feels like it can finally breath.

I'll leave mine on, our engines are kinda... not... pretty to look at with the cover off. When i look at my mustang 5.0 engine i can feel my spirit soar BUT when i look at the 2GR-FSE... well... it just looks so... so... effecient

i took just the front one off last night on my 250....it seems a little louder...
for those that may know...does more air equal higher rpms?...if so then i can say for sure it makes a differnce...im pretty sure i saw an increase of about 100-200 rpms when cruising at 75ish....i think it used to be right above 2000...(those that know please chime in)...on my drive to school today it was closer to 2200....

Npe, like I said its not really louder. Our engine is not loud. In fact it almost sounds like a washing machine at idol. Its actually kind of odd, dont like it myself, I want to hear the 300 hp. the IS350 does sound pretty nice when its opened up at high RPM, just like it should My Sti at idol in my garage would rattle my ****ing house. It sat in that garage and damn strait let you know it was in the garage being fired up.

This is most definitely a placebo effect since the covers could not contribute for better OR worse to performsnce. Well, I guess you could make the argument that the extra weight makes a difference, but it would take very special timing gear to measure it. The front cover does not hinder the intake at all, and might actually help it since the cover will reduce the amount of hot air it ingests from the engine bay.
