    Default Sprint Filter brand new C-Tech intake for Honda Civic Type-R FK8

    Sprint Filter presents C-Tech intakes

    C-Tech is a new family of Sprint Filter products for sports cars and supercars, and is the result of Sprint Filter's more than 65 years of experience in fluid dynamics. It is a product that makes no compromises, drawing on the technologies used by Sprint Filter in motorsports at the highest levels: high performance, lightweight, exclusive and easy to assemble. The first C-Tech airbox is dedicated to Honda's super sporty saloon, the Honda Civic Type-R FK8.
    The airbox for the Honda Civic Type-R FK8 is the result of a long technical collaboration with J.A.S. Motorsport, Honda's long-time partner in the manufacture of touring and rally cars. For two seasons the TCR version of the FK8 designed and built by J.A.S. Motorsport has been equipped with the universal Sprint Filter KD1TCR airbox, and it was therefore easy to use the acquired know-how in the design of an airbox dedicated only to the production version.
    Sprint Filter uses the best carbon fiber available on the market for each airbox of the C-Tech series, processing it exclusively with an autoclave process. One of the product's main focuses is ease of assembly, which is carried out in a few minutes without having to make any changes to the car or adjustment of the carburation. The box includes everything needed: P08 air filter specific for the Sprint Filter filter box, the airbox divided into two half shells made of carbon fiber and equipped with locking clips in burnished steel marked Sprint Filter, sleeve (6 PLY) including hole for oil vapor recovery (with certified pressure and temperature tests), 2 cable glands for repositioning the wiring of the airflow meter. The reduced weight compared to the original airbox (including air filter and sleeve) is significant: the original weighs 2,300 grams (2.3 kg), while the Sprint Filter C-Tech weighs only 811 grams.



    Dyno test data

    All the measurements (made by the Italian tuning magazine Elaborare) were done on a Civic Type R FK8, strictly standard, with 10,000 km of mileage and without upgrading the control unit. There was an increase of 296.8 hp at 6,476 rpm to 311.7 hp at 6,477 rpm. Most incredible are the torque values and the average power utilization range, which is about +40 hp!


    A careful analysis and comparison of the collected instrument data shows an increase in the turbo boost for the version with Sprint Filter airbox, all other conditions being equal (intake air temperature, engine cooling water temperature).



    The increase in the duty cycle of the high-pressure petrol pump can be quantified at around 3%, with a maximum peak of 4%, thanks to the greater demand for fuel due to the higher boost pressure. This increase in boost pressure can therefore be generated by the improved ability to draw air in thanks to the permeable air filter and an adjustment of the intake air flow given by the design of the Sprint Filter C-Tech airbox.
