Hello, Very new here and new to Lexus also. I come from a background on modding and tuning VWs, being new here I had a few questions on the cars because is foreign to me! I appreciate the help and sorry if any of my questions were covered already.

I recently bought a 14 IS350 Fsport and I'm loving the car, sweet thing is it was tuned when I got it and has an axle-back on it! (revs to 7200 rpm) I was doing some general maintenance on in when I first got it and it has a stock intake, I replaced the intake filter to find that the airbox had holes drilled all over it ( not like the intake box mod where it drilled in the front) So I want to replace with and was looking that Lexus actually makes a F sport intake that comes with the upper air box for my model but not the lower but the old 2IS comes with a lower airbox.

I wanted to know if I could use that airbox or and 2011-2013 IS350 intake airbox on my car or does it have to be specific to my 2014-2016/17 model, I see that there are different mounting holes to lock it down with but inspecting my engine bay it looks like the holes could work to add the bolts in. Any help is really appreciated! I'll attach some pictures also.

Thanks a ton for the help!

Mine has this bracket which is odd

Fsport one does not have it nor does it look like most is350s do

 

Welcome to the forum!

Rather than a lengthy answer to your question, see this link: https://www.clublexus.com/forums/bui...ml#post9842534
Lots of pics...each worth a thousand words at least.
There's part numbers and a video.

 

Can anyone please tell me the part number for high beam and low beam for is250?

 

What kind of headlights do you have on your IS250?
Is it the single or dual projector? HID or LED?

 

it is a dual projector LED.

 

You can't replace the bulbs in the LED headlights...mainly because there are no replaceable bulbs in the headlight.
The LED's are part of the headlight.
Did you confirm if it's the actual LED or the controller? The controller is the computer in the headlight that controls the lights.

 

There was moisture inside the headlight, after few days it was showing " check the headlight system" and now the low beam not working.

 

There is a bulletin for the 2014's with moisture in the headlights due to a cracked tab on the top. Given the age of your car it would be out of warranty for the bulletin.
This is most likely the cause of how the moisture got into your headlight.
Honestly the easiest solution would be to find a used headlight...and confirm the tabs on the top are not cracked on it.
