TRD
Performance Air Intake
QUICK FACTS Positive + Best fitting intake of all tested + OEM Quality + A/F Ratios mimic stock intake system + Second Highest Horsepower 3,000-3,500 RPM Negatives – Stock A/F ratios limit power production
Overview: The highest production quality of any of the units reviewed. The TRD Performance Air Intake delivers a factory fit and finish. A/F ratios are not manipulated.
Analysis: Power gains are limited due to a lack of manipulation of the air- fuel ratio. The true potential of this intake will only be realized with a reflash of the factory ECU.
