I have a 2002 IS300 Lexus. I installed the Typhoon 69-8700 kit several months ago. Prior to installing the kit my gas mileage on trips was maximum of 23.8. I just made a 1679 mile trip where my average was 25.3 for the entire trip, the highest was 27.08 and lowest of 22.94, speeds of 60 to 80 MPH.

I have owned 2 98-00 Lexus LS400's. I totaled my first and bought another model one year newer. The first model I owned I dropped the K&N filter into the filter housing and it did all it said it would. On my second LS I removed the filter housing and kept the factory cold air duct in place. It performed exactly the same with one difference.... When the VVTi activates the car sounds like a true V8 demon. I have never heard a car sound so sweet.

Application is 2006 Lexus IS 250 AWD with 205 HP. Very, very detailed excellent installation directions which you can see on this website. If you are looking for sound, fitment, and finish this product nails it. Definitely a more aggressive, throaty, roar that will bring a smile to your face. You will know when you step on the gas. Meanwhile it will be silent on the highway while cruising. It is perfectly engineered to fit in my car with no modifications of any kind and the engine bay covers fit as normal. The chrome pipe peeks out from under the engine bay cover. I think they make these in black now. The car feels slightly more responsive. The horsepower I have no means of testing and it wouldn't be worth my time on a car with such a small output. However HP is guaranteed. The ratings K&N gives are for a IS 350 with 305 HP which then it may be more noticeable. Be aware of the oiling instructions for the filter. Solid construction and reuses your factory oxygen sensor. I actually think my car adjusted after a few days after installation. The first few days felt more responsive and lively. The next few days it felt like the car learned and adjusted engine air flow settings. Again this is all based on feel and not tests. It may just be in my mind. No negative effects for driving in cold temperatures below -20 degrees Fahrenheit.
