Lexus drivers are people that demand quality vehicles full of features and power. First introduced to the United States in 1989, the luxury vehicle division of Toyota Motor Corporation has a well earned reputation for incorporating the highest quality materials and craftsmanship into their manufacturing process. They call this process - The Pursuit of Perfection. It is that ongoing quest for excellence that converts drivers into Lexus evangelists, blissfully spreading the word of how remarkable it is to be a Lexus owner.

Two of the most talked about Lexus models are the IS250 and IS350. Revamped in 2006, the second-generation IS250 produces 204 horsepower at 6400 rpm. While the IS350 with its 3.5-liter V6 engine and redesigned exterior, weighs in at just over 300 horsepower. Both models once more have reclaimed their position as the yardstick for measuring the entry-level luxury sedan class.

Although both sedans list impressive horsepower numbers, Lexus owners have an easy option for more power and torque. AEM, like Lexus, continues their own pursuit for precision by focusing on regaining power lost through factory intake restriction with their Electronically Tuned Intake (ETI) technology.

AEM has two air intakes for 2006-2011 Lexus IS350 models with 3.5 liter engines. Part number 41-1402C has a tube with a gunmetal gray finish and 41-1402P has a tube with a chrome-like finish. These intakes are easy to install and they will add an estimated 11 horsepower at 4400 rpm to your IS350. 2006 to 2013 Lexus IS250 models with 2.5 liter engines get a power boost of an estimated 6.6 horsepower at 5900 rpm with AEM air intake part 41-1406C (gunmetal gray finish) or part 41-1406P (chrome-like finish).

AEM achieves these significant horsepower and torque gains by supplying the engine with cooler outside air and by designing the air intake system to restrict air less than the OEM intake. AEM also uses its revolutionary and fully integrated ETI module to adjust the vehicle's MAF (Mass Air Flow) sensor electronically. The ETI module optimizes the MAF as it sees denser power gaining air being fed into the engine.

  • More Power

  • Great Filtration
  • Attachment for MAF Sensor
  • Attachment for PCV Hose

  • Lifetime Limited Warranty

These large increases in performance are coupled with exceptional engine protection. An AEM Dryflow air filter is included with these air intakes. It allows air to flow with less restriction than a typical paper air filter while it provides outstanding filtration.

AEM Dryflow air filters are easy to clean and reuse. These performance air filter elements can perform for up to 100,000 miles, depending on driving conditions. When servicing is needed, AEM's synthetic cleaner (part 1-1000) is used to quickly dissolve dirt then a rinse with water washes the dirt away. Once dry it is ready to use again.

AEM's Lexus IS350 air intakes 41-1402C and 41-1402P, along with AEM's Lexus IS250 air intakes 41-1406C and 41-1406P come with a heat shield to block hot engine air. The intakes also come with a fitting on the tube for connecting your existing PCV hose.
