Cold Air Intake for 2005-2013 Lexus IS 250 2.5L V6 /2006-2011 IS 350 3.5L V6

Unlock the true potential of your Lexus IS250 or IS350's naturally aspirated V6 engine. The Flashark Cold Air Intake Kit replaces the restrictive factory airbox and plastic intake tract with a smooth, large-bore aluminum intake pipe that routes cooler, denser air directly to your engine — delivering sharper throttle response, stronger mid-range torque, and the satisfying induction sound that the factory system completely suppresses.

Built with a mandrel-bent aluminum pipe finished in durable matte black, paired with a high-flow red cone filter, this kit comes with all hardware for a true bolt-on installation. No cutting, no welding, no fabrication — just basic hand tools and about 60-90 minutes in your driveway.

Compatible with 2005-2013 Lexus IS250 (2.5L V6) and 2006-2011 Lexus IS350 (3.5L V6).

Why Upgrade Your Intake?

The factory intake on the IS250 and IS350 was engineered for one thing: quiet luxury. Lexus deliberately muffled the 4GR-FSE and 2GR-FSE V6 engines — restricting airflow with a bulky plastic airbox, dense paper filter, and deliberately narrow tubing — all to reduce cabin noise.

That compromise costs you real performance. The Flashark Cold Air Intake removes it:

• Immediate throttle response — the V6 feels alive from the first press of the pedal; no hesitation, no lag
• Stronger mid-range pull — the IS250/IS350 pulls harder between 3,000–6,000 RPM where spirited driving actually happens
• Improved fuel efficiency — more efficient combustion under light load reduces fuel trim corrections
• The V6 induction sound — Lexus muted these engines on purpose; the Flashark intake finally lets the 4GR and 2GR breathe (and sound) like they should
• Reusable filter forever — no more $30+ OEM paper elements every 15,000 miles
