Just changed the two engine air filters on my 2007 LS460. I noticed in the top cover of the filter box there appears to me an open cell foam post-filter held in place by plastic mesh. I couldn't see this - based on feel alone. Anybody know if this is correct and, if so, does the foam filter ever need changed?

 

Anybody....... Bueller....... Anybody.......?????

 

The only thing that should be changed (Based on owners manual) is the removable air filters, so you are good just keep changing the engine filter every 15K.

 

I have k&n filters in there for the long haul. (i know some people here don't agree with that move)

I wonder if this other filter can be removed to further improve flow?

 

15k or 30k?

 

15K unless you live in a sandy climate then less than that.

 

The more you increase your air flow the more contaminants are likely to enter the engine. Your choice! I never change or modify anything that can impair the internal parts of the engine.

 

I guess after driving an LS with a CAI for a few years impressed me beyond words.

I had more volume under acceleration than some cars with exhaust!

When i added exhaust my car then sounded exotic.

 

im rocking the dual k&n no problems.... petebabes what cai you rocking????

 

Absolutely. I can tell you first hand stories on K&N's. Scary stuff.

 

I have the dual k&n cartridge filters now.

I'm sorry i didn't specify, it was my previous LS430 which had the cai.

The cai that the company in MD is trying to create will likely be my first mod once my car drives out of warranty.

 

oh because I was wondering where i have been. yeah no worries on my part though it is what it is... good luck on your cai..
