I have searched for air filters ,using google and in the k&n web site , and there is nothing for the 2014 is 350 , but there are some filters for the 2013 is350 and also the 2013&2014 gs 350 . Anyway did anyone try the one for the old is350 or the gs ?
I'm looking into buying an air filter ASAP .

Look at K&N #33-2345 pic and compare to yours. This is my next step.

The GS filter fits.. the IS filter does not. I bought mine on ebay... 33-2452

Can you notice any difference? performance? MPG? sound?

BOBFSPORT

Sound yes. Anything else is doubtful.

Marginal sound increase... not noticeable to most people. As far as performance and MPG, its too early to tell, but i highly doubt there will be any significant gains.

Im also using a JoeZ intake tube... so i no longer have the noise generator.

BTW they all look the same ... I think your best chance to find out is to measure your filter and compare it with the available filters .

Thanks for the information ،now the only thing remaing is ordering the filter . I was going to measure my filter and compare with the one from k&n , but there is still a possibility of having a slightly diff. shape .

I have already confirmed to you the part number to order.... 33-2452... it is for the GS460.

AMNss

I meant that I was going to measure the filter , but now there is no need to measure it .

AMNss

I just order the filter , and I'm waiting for it to be delivered .

Hope it fits. 33-2452 is for the 14 IS250 but I thought you were asking about the 14 IS350? Let us know. Thanks.

The stock filter is thick with pleats. The K&N is more open allowing more junk in the engine. If the sound of your engine wearing out is worth the difference, go for it. I've never seen any gain with K&N, just sound. And it's been shown that the K&N allows more particulate through as well. Your gamble.

Sounds great... gamble... sure, but it's trial and error right? At least until f-sport comes out with an intake system...
I ordered the 33-2452, fits perfectly... and 44.99, so just a little wallet shaking...

Yeah I'm looking forward for a cold air intake , but in the meantime I will get the replacement filter . BTW I have an old k&n filter installed on my second car for almost 5 years , if not more ..., and I had no problem what so ever related to the air filter , and my brother also installed a filter for 6 years and no problem . Anyway the only problem which you may face comes after cleaning the filter since many people dosen't leave it to dry .

AMNss

I received it few days ago and I'm waiting until I finish from taking my car to the service then I will install it . The plastic bag in which the filter is in is full of oil similar to what happened with me regarding my old filter , so I left the air filter out of the bag to let it dry .
