The 2006-2011 Toyota Yaris 1.5L 1NZ-FE is one of the most reliable economy engines Toyota ever built — but the factory air intake was engineered for a single goal: silence. The multi-chamber plastic airbox, paper filter, and restrictive snorkel prioritize cabin quietness over airflow, leaving the 1NZ-FE feeling gutless above 3,500 RPM and sluggish off the line with the A/C running.

The FLASHARK Cold Air Intake Kit replaces the entire factory intake tract with a mandrel-bent aluminum tube and a high-flow dry cone filter. Real-world gains are 2-5 WHP with improved throttle response across the rev range — the difference between waiting for the engine to catch up and the car actually moving when you press the pedal. No ECU tune needed; the factory 1NZ-FE management adapts automatically.

At $78.95, this is the most affordable bolt-on upgrade available for the Yaris platform. Installation takes 30-60 minutes with basic hand tools, no cutting or permanent modifications. The dry filter is fully washable and reusable, saving you money on paper replacements for the life of the vehicle. Compatible with all 2006-2011 Yaris hatchback and sedan trims (CE, LE, S, Base) as well as the Canadian RS.

Key Features

Mandrel-Bent Aluminum Intake Tube — 6061 aluminum with black powder-coated finish. A smooth internal surface eliminates turbulence in the factory plastic airbox, improving airflow velocity.

High-Flow Dry Cone Filter — No oil required. Captures 95%+ of airborne particles without the contamination risk of oiled filters. Fully washable and reusable.

Sharper Throttle Response — Noticeably improved pedal feel, especially from a stop and when merging with the A/C on, where the Yaris needs it most.

Bolt-On Installation — Uses factory mounting points and all OEM sensor provisions. No cutting, drilling, or permanent modifications. 30-60 minutes with basic hand tools.

Factory ECU Compatible — Designed for the 1NZ-FE's MAF-based fuel system. The OEM ECU adapts automatically via fuel trim learning — no tune required.

All Trims, Both Bodies — Compatible with CE, LE, S, Base (USDM) and RS (Canada), in both hatchback and sedan body styles.
