Infinity Design Carbon Intake System Honda Civic Type R FL5 (2023+)

The latest Honda Civic Type-R FL5 is a highly potent sports car which is a huge amount of fun to drive with a formidable 325hp and 310 lb.ft torque.

However, it does lack something and this is evidence from just hearing the engine under normal driving and looking under the engine bay. The intake has a convoluted air path and small opening for air.

We took a radical approach to the design using a large expanding tube with integrated MAF housing feeding into a completely redesigned airbox with significantly larger volume and a 80% enlarged opening.

Our signature double cone large surface area air filter is used with it's 175mm opening.  This is housed in the air filter housing and the system is clamped together.

Results

Initial on road results are excellent with a very noticeable improvement in throttle response,  a noticeable power improvement throughout the rpm range and a more resonant and deeper / louder induction road under load.

The wave of torque just makes this light coupe accelerate in every gear even better than before.  Coupled with the induction sound and throttle response this sophisticated fully developed and engineered system adds class and a thorough dose of excitement and enjoyment to the FL5

Dyno Testing
 

Tested on an independent MAHA 500 dynomometer with a car with Milltek cat back exhaust.

Stock power
330hp | 320 lb.ft 

Power with Intake 

347hp | 335 lb.ft

Power gains start from the beginning of the rpm range and then increase from 3500rpm to 7000rpm with significant gains of 20hp through the rpm range clearly demonstrating the effectiveness of the larger and smoother flowing intake.
