2017+ Civic Type R FK8 High Volume Intake System

Installation Guide

Introducing our High Volume Intake System for the 2017+ Honda Civic Type-R
Patent No. D902,255

**International models may be required to use a 6-8mm cap on the evap fitting. In particular European/Australia models. 

Fitment Notes:

• FITS ALL 2017+ HONDA CIVIC TYPE-R MODELS INCLUDING 6MT, CVT, RHD, INTERNATIONAL MODELS, ETC
• FITS FACTORY TURBOCHARGER INLET PIPE OR PRL MOTORSPORTS INLET PIPE

Please Read Before Ordering:

• NO TUNE REQUIRED FOR STREET MAF HOUSING
• RACE MAF TUNE / MAF SCALING CALIBRATION REQUIRED FOR RACE MAF OPTION

Our FK8 Civic Type-R High Volume Intake system utilizes a 6" cone filter and billet 2-piece MAF housing with velocity stack(s) to allow maximum airflow while delivering proper fuel trims. The HDPE rotomolded air box utilizes the factory air duct and seal for optimal airflow and heatsoak reduction. Custom molded 4-ply silicone allows for all components to be safely attached without obstructing airflow.

• (1) Rotomold Air Box
• (1) 6" Air Filter
• (4) Stainless Steel Breeze Lined Clamps
• Stainless hardware
• Wire Loom

All testing was performed on the same day with a rather mild 55 degree Fahrenheit day and moderate humidity. We started all single dyno pulls at 174 degrees, while continuous (back-to-back) dyno pulls start at 174 degrees and end around 197 degrees.

For our first comparison we tested the factory intake system on KTuner's stock equivalent ECU map versus our High Volume Intake System on KTuner's stock equivalent ECU map for an apples-to-apples comparison. Run 2 was the coolest (174 degree starting temp) for both setups. We saw an 11 - 12 horsepower peak gain and 32 horsepower gain throughout the mid-range over the factory intake system.


Continuous dyno pulls and testing under the same conditions produce identical gains time after time. Even our hottest runs, Run 4 (197 degree starting temp), showed a 5 horsepower peak gain and 26 horsepower gain throughout the mid-range over the factory intake system.

Next, we uploaded KTuner's Stage 1 ECU map with the factory intake system and our High Volume Intake System. The coolest runs, Run 2, showed an 8-9 horsepower peak gain and 25 horsepower gain throughout the mid-range.

The hottest runs, Run 5, showed a 9 horsepower peak gain and 18 horsepower gain throughout the mid-range.


One of our main focuses with this intake system was to offer a factory-like fuel trims (much like our 1.5T Cobra CAI & SRI) for optimal drivability and performance. We spent quite a bit of time designing what we determined is the best intake system/MAF housing on the market. Thus far we have seen Short Term Fuel Trims within +2-4% of the factory. We have a few more tricks up our sleeve, but are very happy and confident with what we have currently.
