2005 ls430 cold air intake
Does anyone have a cold air intake (CAI)on their 2005 LS430? I see several options for 01-03 models and one Weapon R CAI for 01-04 models but can't get any confirmation if they will fit my 2005 LS430. Any recommendations?

Factory cold air inlet
Here is your factory cold air intake.
As Striker eludes, remove the restrictive charcoal element located underside the air filter cover.(17705)

Wow good to know. I have never looked at what’s in that box before. Also, it is near the MAF sensor. Is there any additional reasons why they decided to have this filter in place?

This, I find it kinda ironic and overkill though since at idle you have very high vacuum and the electric TB should be near closed when you shut the engine off.

If you do find one, please keep the oem airbox so the next owner can undo your "performance mod"

First immediate effect which I noticed - engine revs up slightly faster. Second effect noticed later - when driving and quickly unpressing accelerator pedal, the car doesn’t abruptly slow down the current speed.
MPG remained the same.
I looked at this carbon filter and found out multiple layers of filtering materials. There is no way this does not slow down the air flow. I assume this was designed for emission control like you said but also is there a possibility this filter creates some sort of back pressure or more smoother air flow?
I researched this subject a little bit today and also found out that this filter IS NOT include in European cars. If anyone could confirm please that UK LS430 doesn’t have this filter?
