I have research K&N in full depth before going forward and 90% of people were happy and 10% were naysayer that it will spoil engine, etc. Due to the majority, I went ahead and never had an issue in actual usage in UAE dusty conditions.
In my Mustang I used it for 2 years, in my Pajero I'm using since 4-5 years.
I have no clue on IS 300 tbh. I had GS430 in the past when I was young and moved from 4 cyl Accord to 8 cyl Lexus so never felt a need for more power but actually concerned for how to put that 300 hp in a straight line.
Do share your research and experience about IS300 and K&N if you decide to go ahead.
Thank you Gaurav for the in depth advice.
Does this installation come with any draw backs?
Also do you have any idea if 2008 IS 300 F Sport air intake system fits IS 300 2008? From the videos in Youtube, I saw that there are many people you installed but just wanted to ask another expert.
Welcome NSQRD, very different user id.
For K&N, I have two experience to share from my Mustang for road and Pajero for offroad.
There is a noticeable shift in throttle response (free flow) you will feel after the upgrade, in my opinion, air filter upgrade is not for additional 5-10 hp, but for quick delivery of existing hp that your car has. This does make you feel the car is more responsive and crisp in throttle response.
For road use, I will highly recommend K&N and better if you can get cone replacement for cold air intake, that practically makes a good difference. If you can't then upgrade a standard OEM with box replacement K&N is also worth the money.
For offroad use, as much as I love K&N but I hate its extensive maintenance to clean air dry and oil almost every month after 3-4 offroad sand drives. So now I keep the OEM for every week playing and switch to K&N if I'm heading to some extreme areas for long hill climb to get a better quick response.
For buying you can compare local price with K&N website, as I found their website was cheaper including the shipping and package came in 3 days times with FedEx. This also made me tension free that I'm buying an original one and not replica's
Last but not least K&N website warranty is awesome, I broke my Pajero filter and send them a few pictures on email and they send me the new one without asking anything within 3 days with FedEx without even shipping charges.

I am looking to upgrade the performance of my 2008 IS 300 by adding a high airflow K&N Air Filter intake system.
Where would be the best place to purchase one and also would the IS 300 F Sport intake system fit on mine?
