Does anyone know what the part number is for the 3.5L engine cover logo for a 17' IS? I know they sell the 3.0L emblem logo for the GX, but I couldn't find anything.

 

Not exactly sure what the question is vs the thread title.
The engine cover only has the Lexus logo on it...so it's not missing any logos, the Lexus logo is the only one.
The logo comes with the cover...you can't buy it seperately. The part number for the cover is 11209-31320.
If you're looking for a "3.5L" logo for the engine cover, then you will need to source it from another model that has it.

If you can find another model that has the logo you are looking for, we can help you find that.

 

Cool that's what I figured. Just wanted to make sure. Thanks!
