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

Lexus IS250 / IS350 Cold Air Intake FAQ (2005–2013 Performance Intake Kit)
Q1: What Lexus IS models does this cold air intake fit?
A1: This cold air intake kit is designed for 2005–2013 Lexus IS250 (2.5L V6) and 2006–2011 Lexus IS350 (3.5L V6). It is engineered for factory engine configurations and bolt-on installation without major modification.
Q2: Will this intake fit a 2008 Lexus IS250 2.5L?
A2: Yes. The 2008 Lexus IS250 with the 4GR-FSE 2.5L V6 is fully compatible. It is a direct replacement for the factory airbox system.
Q3: Does this cold air intake fit Lexus IS350 3.5L V6?
A3: Yes. It fits 2006–2011 Lexus IS350 models equipped with the 2GR-FSE 3.5L V6 engine. Always confirm engine layout before installation.
Q4: Will this intake increase horsepower on Lexus IS250 or IS350?
A4: Most users see a gain of around 5–12 horsepower depending on tuning and supporting modifications. The most noticeable improvement is throttle response and engine sound rather than peak horsepower.
Q5: Do I need a tune after installing this cold air intake?
A5: A tune is not required for basic installation. The ECU can adapt to airflow changes. However, a performance tune can help maximize gains, especially on IS350 models.
Q6: Will this intake improve throttle response?
A6: Yes. Reduced intake restriction allows the engine to respond faster, especially in mid-to-high RPM driving conditions.
Q7: Does this intake improve fuel economy?
A7: Slight MPG improvement is possible under normal driving, but results depend heavily on driving style. Aggressive acceleration will reduce any efficiency gains.
Q8: Will this cold air intake make my Lexus louder?
A8: Yes. It produces a deeper induction sound and stronger intake noise under acceleration, especially above 3,000 RPM.
Q9: Will this intake cause a check engine light (CEL)?
A9: A properly installed intake should not trigger CEL. Issues usually come from loose clamps, vacuum leaks, or incorrect sensor installation.
Q10: Is this a true cold air intake or short ram intake?
A10: This kit is designed as a cold air intake system that improves airflow while reducing hot engine air exposure compared to stock airbox designs.
Q11: Is installation difficult for Lexus IS intake kit?
A11: Installation is simple and usually takes 30–60 minutes with basic tools. No cutting or permanent modification is required.
Q12: Can I install this intake myself at home?
A12: Yes. It is a bolt-on modification suitable for DIY installation. Most users can install it in a driveway or garage.
Q13: Will this intake work with factory MAF sensor?
A13: Yes. It is designed to retain and properly mount the factory MAF sensor for accurate airflow readings.
Q14: Will this intake cause heat soak issues?
A14: Some heat soak may occur in stop-and-go traffic, but airflow improves significantly during driving conditions compared to stock intake.
Q15: Is the air filter reusable and washable?
A15: Yes. The included high-flow filter is washable and reusable, designed for long-term performance and easy maintenance.
