Performance Air Intake W/Heat Shield for Lexus IS 250 (2005-2013) with 2.5L V6 Engine Black

Precision Induction for the Lexus 4GR-FSE: Performance Intake with Heat Shield

Who It’s For: Engineered for Lexus IS 250 owners running the 4GR-FSE powerplant who are tired of the stock sluggishness and want to hear that V6 sing.

The Symptom: The factory intake on the 4GR-FSE is designed for absolute silence, not peak volumetric efficiency. It uses a series of restrictive resonator chambers and accordion-style plastic tubing that creates massive air turbulence, effectively choking the engine’s throttle response when you’re trying to merge or pull away from a stop. This makes the IS 250 feel heavier than it actually is, leaving a noticeable lag between your foot hitting the pedal and the car actually responding.

The Engineering Fix: This system replaces that restrictive factory plumbing with a mandrel-bent T304 aluminum tube. By smoothing out the airflow path and utilizing a dedicated heat shield to isolate the filter from hot engine bay air, we significantly increase the oxygen density entering the combustion chamber. This results in a much sharper throttle snap and a deep, mechanical induction growl that the factory plastic boxes are designed to hide.

Why Mechanics Choose This Kit

• Optimized Volumetric Efficiency: Gains of up to 10% in horsepower and torque by reducing the pumping losses inherent in the stock baffled intake.
• V6 Induction Roar: Removes the factory sound-deadening resonators to provide a throaty, aggressive tone under heavy acceleration while remaining civilized at cruise.
• Premium Material Science: Constructed from T304 lightweight aluminum for heat dissipation and paired with a high-flow, washable cotton filter that only requires servicing every 50,000 miles.
