Performance Cold Air Intake System for Lexus IS250 & IS350 – Enhanced V6 Response & Sound

This performance intake system is engineered to maximize your Lexus's breathing potential. By replacing the restrictive factory air box with a high-velocity induction path, this kit allows the V6 engine to pull in a larger volume of oxygen-rich air with significantly less effort. The result is a more energetic combustion cycle, providing crisper throttle sensitivity and more fluid acceleration, especially in the low and mid-range RPMs, giving your IS a more responsive and engaging feel on the road.

Tailored specifically for the 2.5L and 3.5L V6 powerplants, this upgrade unlocks hidden engine efficiency while maintaining the smooth, refined drivability expected from the Lexus platform. In addition to the performance gains, it grants your vehicle a deeper, more authoritative induction note under load, while the clean construction ensures the engine bay looks polished and purpose-built.

Key Features & Performance Benefits

• Unrestricted Induction: Replaces narrow factory ducting with a high-flow pathway to satisfy the V6 engine’s demand for air.

• Instant Throttle Feedback: Eliminates the "laggy" feeling of the stock intake for more immediate engine reaction.

• Cooler Intake Charges: Channels denser air into the manifold to support more consistent power delivery and acceleration.

• Aggressive Sound Profile: Adds a throaty, sportier growl to the engine during heavy acceleration.

• Direct Fitment: Engineered to utilize factory mounting locations for a secure and reliable installation.

Installation Tip

Disconnect the NEGATIVE GROUND CABLE from the battery before starting the installation and keep it off for at least one minute after you finish. This reset allows the engine's computer to learn the new airflow parameters. Ensure the engine is completely cool before beginning work.
