Eventuri Carbon Turbo Tube Package with V2 MAF Tube for Honda Civic Type R FK8

The Eventuri EVE-FK8V2-CF-CHG Carbon Fibre Turbo Tube Package is a premium intake upgrade developed for the 2017–2021 Honda Civic Type R FK8, powered by Honda’s 2.0-litre turbocharged K20C1 VTEC Turbo engine.

Rather than simply replacing the original inlet tube with a cosmetic carbon component, Eventuri engineered the FK8 turbo tube around three important areas: air volume, airflow quality and thermal management.

Larger 78 mm Intake Path

The factory FK8 turbo inlet tube has an internal diameter of approximately 63 mm. Eventuri increases the inlet section to approximately 78 mm, matching its V2 MAF tube and maintaining the larger diameter through much of the inlet path.

This represents an increase in cross-sectional area of more than 53%, allowing the turbocharger to draw air through a substantially less restrictive intake path.

Reducing restriction before the turbo can become increasingly important on modified FK8 Type R applications where boost pressure and airflow demand are higher than standard.

Improved Turbo Response

The larger-volume intake path allows the turbocharger to draw air more efficiently, potentially allowing it to reach target boost earlier and operate with reduced inlet restriction.

Eventuri’s testing of its original FK8 turbo tube arrangement showed approximately 5 hp and 5 ft-lb peak gains on a stock-software FK8, while improvements of up to approximately 15 hp and 18 ft-lb were recorded below 4,000 rpm.

These figures should be treated as manufacturer development results rather than guaranteed power increases. Actual performance will depend on the vehicle, ECU calibration, fuel, environmental conditions and other modifications.

Smooth Pre-Preg Carbon Fibre Construction

Eventuri manufactures the inlet tube using 100% pre-preg carbon fibre without a fibreglass inner layer.

This construction allows Eventuri to create a smooth internal surface and carefully controlled tube geometry. The smoother airflow path helps minimise unnecessary turbulence as air travels from the MAF section towards the turbocharger.

The carbon construction also provides significantly greater visual appeal than the factory cast inlet pipe, making this a particularly attractive upgrade for show-quality and enthusiast FK8 engine bays.

Reduced Heat Transfer

The standard aluminium inlet assembly is mounted close to the turbocharger and can conduct heat into the intake system.

Eventuri uses a CNC-machined turbo flange together with a silicone coupling arrangement to separate the carbon tube from direct contact with the hot turbocharger flange.

Combined with the comparatively low through-wall thermal conductivity of carbon fibre, this arrangement is designed to minimise heat transfer into the incoming airflow.

Includes V2 Carbon MAF Tube

An important distinction with SKU EVE-FK8V2-CF-CHG is that this package includes the updated Eventuri V2 carbon MAF tube.

The earlier V1 Eventuri MAF tube reduces in diameter after the MAF sensor and therefore does not correctly match the larger carbon turbo tube.

The V2 MAF tube maintains the larger approximately 78 mm airflow path after the MAF sensor, creating a smoother transition into the Eventuri turbo tube.

This makes EVE-FK8V2-CF-CHG particularly useful for owners of an earlier Eventuri FK8 intake who need the V2 MAF conversion as part of the turbo tube upgrade.

Designed for the Eventuri FK8 Intake

Important: this is not a universal replacement turbo inlet pipe and should not be purchased on the assumption that it fits directly to the factory Honda airbox.

The Eventuri FK8 carbon turbo tube was designed to integrate with the Eventuri Civic Type R FK8 intake system.

If your vehicle already has an Eventuri intake with the updated V2 MAF tube, verify whether the tube-only package is more appropriate before ordering.

Ideal for Standard and Tuned FK8 Type R Builds

The Eventuri turbo tube can provide benefits on standard vehicles, but the reduction in intake restriction becomes particularly relevant as turbo airflow demand increases.

It is therefore an excellent supporting modification for FK8 builds using upgrades such as:

• ECU remapping
• Performance exhaust systems
• Sports catalysts or downpipes
• Upgraded intercoolers
• Higher boost calibrations
• Hybrid or upgraded turbochargers
• Track-focused engine packages

For heavily modified vehicles, tuning should always be carried out by an experienced Honda performance specialist.

Premium Performance Upgrade for UK FK8 Owners

For UK Honda enthusiasts looking to buy an Eventuri FK8 turbo inlet upgrade, EVE-FK8V2-CF-CHG combines functional airflow improvements with Eventuri’s distinctive carbon fibre construction.

It is particularly attractive for owners who already have an earlier Eventuri intake and want to upgrade the complete MAF-to-turbo airflow path while retaining a premium OEM-style installation.

FAQ

Does the Eventuri EVE-FK8V2-CF-CHG fit a UK Honda Civic Type R FK8?

Yes. The application is the FK8-generation Honda Civic Type R with the 2.0-litre turbocharged K20C1 engine. UK FK8 Type R models were sold from 2017 through 2021.

However, the turbo tube is designed to integrate with the Eventuri FK8 intake system rather than being a standalone replacement for the complete factory Honda intake.

Does EVE-FK8V2-CF-CHG include the V2 MAF tube?

Yes. This specific package includes the updated Eventuri V2 carbon MAF tube as well as the carbon turbo tube.

This distinction is important because Eventuri also produced a turbo-tube-only configuration for customers whose FK8 Eventuri intake already had the updated V2 MAF tube.

Why does the FK8 need the V2 Eventuri MAF tube?

The earlier V1 MAF tube reduces in diameter after the MAF sensor. The V2 tube maintains the larger approximately 78 mm section so that it matches the Eventuri carbon turbo tube.

This provides a smoother, larger airflow path towards the turbocharger.

Will this Eventuri turbo tube fit the standard Honda FK8 airbox?

No. The Eventuri FK8 carbon turbo tube was designed around the Eventuri intake system.

Customers with a standard Honda intake should not order the kit assuming it is a simple universal replacement pipe.

What engine does this Eventuri turbo tube fit?

It is designed for the 2.0-litre VTEC Turbo K20C1 engine fitted to the FK8 Honda Civic Type R.

It should not be assumed to fit other Honda K20 engines simply because they share the K20 engine family name.

Does an Eventuri turbo tube increase power on an FK8 Type R?

Eventuri’s development testing of the original system reported approximately 5 hp and 5 ft-lb peak improvement on a stock-software FK8, with increases reaching approximately 15 hp and 18 ft-lb below 4,000 rpm.

Power gains are not guaranteed and will vary according to ECU calibration, vehicle condition, fuel, ambient temperature and other modifications.

Is the Eventuri turbo tube worthwhile on a tuned FK8?

It can be particularly useful on tuned engines because increasing turbocharger airflow demand makes restriction on the inlet side more significant.

Cars running ECU tuning, exhaust modifications, upgraded intercoolers or higher-output turbochargers can therefore benefit from improving the airflow path before the turbo.

Does this fit the Honda Civic Type R FL5?

No. This SKU is specifically for the FK8 Civic Type R. The later FL5 uses a different intake arrangement and has its own Eventuri components.
