Hi Everyone. I wanted to check with regulars to get some takes on this.

I came across a mod for the Lexus IS 350 that some people have posted on forums and youtube vids involving cutting a hole in the airbox to increase the amount of air coming into the intake.
From what it looked like, it gave a noticeable performance/acceleration increase in the videos that I saw.

Obviously a high flow air filter or new air intake would be better in general, but i'm looking to minimize costs and see which cheap mods work the best.
I understand that air intakes are designed specific ways to maximize airflow, and that putting a hole in the airbox will suck in air from the engine bay which could be warmer than the air coming in the beginning of the intake.
I'm just looking for any input on anybody who has tried it or heard about it and what they found with it.

As presumed, just cutting a hole you will suck up warm air. To find the cheapest resolution..., keep in mind that the actual filter should be maintained new or fresh preferably KnN and for the box create a insert cut out path vented scooping to fender to increase air. I guess a hardware store that sells hosing and plastic fittings.
