Don't do an air intake system
 

Really the title is the question...is there any reason or anyone out there not doing an air intake system for a particular reason?

I am looking to make a few mods and this is where I will likely start followed by exhaust.

Obviously, if it isn't available on all GS's then that does not warrant a response but I do know it is available for GS350.

i never do intake. don't need the extra sound in my cabin, and it's not visible on exterior

If you want your car to sound a little louder Intake will give you a better effect then exhaust itself.......I have both of them on my car and I am absolutely loving it and if you want your car to sound more aggressive Intake is a must done in mine mind.....
