Hello, I need your opinion until i do real CAI for my car i want to do something better than stock one.

There is a small (4x4 or so) fresh air grate right in front of the air box to feed it cool air from the front, from behind the headlight. It does a pretty good job of getting SOME cool air to the intake.
See the circled area on my picture...

Air temp is a factor in the combustion equation, but keep in mind that the sensors in the intake were designed as a system, and you could get some gremlins if you start messing with that area too much. I like the suggestion of 1990TSIAWDTALON to explore the airflow going into the box, and perhaps enlarging the snorkel a bit for improved WOT airflow. The place where you can really drop some degrees is at the intercooler, and simple water sprayer there (enhanced evaporative cooling) or improved airflow through it will likely do a lot more for lowered intake air temperature than at the filter box. The classic CAI effect is more pronounced for N/A cars, especially when they relocate the inlet to a cooler area within the engine bay (or outside of it), as the compression of the turbo raises the temperature a lot (hence the intercooler). The more boost, the more the temp increase, too. There are aftermarket intercoolers you could consider as well, though I think in most cases those are overkill too, unless boost is quite high. If the temp is too cold you could have poor combustion through lack of atomization/ evaporation of fuel (think of cold starting!). Drivability is important to keep in mind as you seek more power, unless this is just a race car.

I did something similar to your picture as well as remove the plastic vent part that 1990tsiawdtalon mentioned. I will say this my car is mostly stock and I noticed absolutely no improvement. The car was designed to use that airbox so even though its restrictions are there your car was designed around that so on a stock car I'd say just wait (unless you just want to tinker).

If you want colder Intake temps, you will need to improve the intercooler system, however it is best for you. Some guys switch to a Supra intercooler I think, or another model of car that has a thicker core. Possibly an Evo but I am not sure on either of those suggestions. I run front mounts but mine are just race cars in junker looking bodies. I can daily them but I have other cars for that. Sleepers are what I call them.

I bought VRSF front mount IC so I want some more air but not too hot air I think this mod will be best so far

can make me take too much hot air. What u think ?

You can remove these 2 pieces and get a bit more cool air flow....
