Description
Upgrade the airflow and throttle response of your Honda Integra Type S with the Infinity Design Honda Integra Type S Intake. Designed to address the restrictive factory intake system, this high-performance intake uses a significantly enlarged air path, a large-volume redesigned airbox, an integrated MAF housing, and Infinity Design's signature high-surface-area double-cone air filter.
The latest Honda Integra Type S is a highly potent sports car that delivers a formidable 325 HP and 310 lb-ft of torque. However, the factory intake system leaves room for improvement, which is evident when listening to the engine during normal driving and inspecting the engine bay. The OEM intake features a convoluted air path and a relatively small opening for incoming air.
Infinity Design took a radical approach to the intake design, utilizing a large expanding tube with an integrated MAF housing that feeds into a completely redesigned airbox with significantly greater volume and an 80% enlarged opening. The system uses Infinity Design's signature double-cone, large-surface-area air filter with a 175 mm opening. The filter is housed within the air filter housing, and the complete system is securely clamped together.
In addition to the intake system, Infinity Design developed a standalone turbo inlet tube that increases airflow volume and provides a smoother radius into the turbocharger, helping to reduce turbulence.

Intake Design
The Infinity Design intake system was developed to significantly improve the airflow characteristics of the Honda Integra Type S while maintaining an efficient intake path.
The OEM system features a small opening and a standard panel filter with a relatively small cross-sectional area connected to a simple intake tube. Infinity Design developed a system that follows the same general intake path while substantially enlarging the air opening and incorporating its signature large Venturi tube into a vastly larger-volume airbox.
The front inlet feed has been designed with double the cross-sectional area, providing a more than adequate increase in available airflow.
After multiple design iterations, this configuration provided the best airflow characteristics during CFD analysis. Testing showed less turbulence than the OEM system while providing vastly increased airflow.
The results on both the dynamometer and during road driving were excellent, with vastly improved throttle response and improvements in low-end torque response. During normal and spirited driving, the engine feels even more eager to accelerate throughout the RPM range, whether under partial or full load.
Development Process
During the development process, Infinity Design created multiple prototypes and models to optimize the intake system.
The OEM system uses a small opening, a standard panel filter with a small cross-sectional area, and a simple intake tube.
Infinity Design developed a replacement system that follows the same intake path but features a significantly enlarged air opening, a signature large Venturi tube, and a vastly larger-volume airbox. The front inlet feed has double the cross-sectional area of the OEM design, providing a substantial increase in available airflow.
Following multiple iterations, this design method delivered the best results under CFD analysis, demonstrating reduced turbulence compared with the OEM intake while substantially increasing airflow.
Road testing and dynamometer testing confirmed the improvements, including significantly improved throttle response and low-end torque response. Under both normal and spirited driving conditions, the engine feels more responsive and eager to accelerate at every RPM, whether operating under partial or full load.
High-Flow Air Filter and Intake Temperatures
The Infinity Design intake uses a bespoke short-stack, high-surface-area air filter that is larger than any cone filter design currently offered on the market, with a huge 170 mm (6 3/4") opening.
The filter is designed to take full advantage of the intake tubes by altering the direction of airflow toward the outer walls. Positioning the air filter in front of the inlet tube allows the system to achieve the largest possible velocity stack.
The intake system is designed around high airflow capacity while maintaining an optimized airflow path into the turbocharger.
Performance Testing
Dyno testing was performed under strictly controlled conditions on an independent Maha MSR500 dynamometer to provide a true and realistic performance comparison.
The stock Honda Integra Type S produced almost exactly the output quoted by the manufacturer, recording 330 BHP with a smooth and natural power curve.
After installation of the Infinity Design intake system, the vehicle achieved 347 BHP.
This represents a significant gain of 17 BHP.
From 2,500 to 7,000 RPM, torque and power increases consistently throughout the RPM range. At 5,500 RPM, the engine demonstrates significant gains in both horsepower and torque.
Run-down losses remained identical between both tests, as did the ambient temperature. Both sets of tests were performed with identical starting oil and coolant temperatures.
