The K&N 69-8701TP Typhoon air intake system is a free-flowing, mandrel-bent aluminum tube air induction system designed to fit some Lexus IS250 and IS350 models. The restrictive factory air filter and air intake housing are replaced by the K&N Typhoon air intake which is designed to dramatically reduce air flow restriction as it smoothes and straightens air flow. This allows your engine to inhale a larger amount of air than the factory air intake. More air means more usable power and acceleration throughout the engine’s RPM range. The 69-8701TP air intake comes with a black rubber topped K&N high-flow air filter and a heat shield that installs into the previous air box space. Air is directed through the intake tube into the engine’s throttle body for a guaranteed power gain. The intake tube has an attractive chrome-like finish that's made to last and it accommodates the factory mass air flow sensor and crank case vent hose. The oversized cone shaped air filter can be used for up to 100,000 miles before servicing is needed depending on driving conditions. This air intake is relatively easy to install usually in 90 minutes or less using existing factory mounting points. The tools needed are a screwdriver, diagonal cutters, needle nose pliers, ratchet set and some wrenches. This air intake cannot be sold in California. It is not legal for use in California or other states adopting California emission standards.

Product Reviews      Review part 69-8701TP

 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.
