PRL Motorsports 2023+ Honda Civic Type-R FL5 Titanium Turbocharger Inlet Pipe Kit

The stock turbocharger inlet pipe on the FL5 Type-R restricts airflow before it reaches the compressor. PRL Motorsports designed this kit to eliminate that bottleneck with a larger-diameter, two-piece inlet system that bolts directly in place of the factory pipe.

The kit uses a cast aluminum inlet piece that matches the turbocharger compressor opening at 64mm ID, then transitions to an 80mm OD (78mm ID) titanium crossover pipe. PRL states this configuration provides over 50% more airflow volume compared to the stock inlet pipe, with improved bottom-end power and faster turbo spool. Three high-temp 4-ply silicone couplers and seven 304 stainless steel interlocking worm clamps handle all connections.

This is a direct bolt-on kit that fits all 2023+ FL5 variants, including right-hand drive and international models. No ECU calibration is required. Important: this inlet pipe is only compatible with the PRL High Volume Intake and will not work with the stock airbox.

Application List

• 2023+ Honda Civic Type-R FL5 (all variants, including RHD and international models)

  Note: Only compatible with PRL High Volume Intake

• Over 50% increase in airflow volume vs. stock: The larger-diameter inlet path feeds more air to the turbo compressor, reducing the restriction that limits the factory setup.
• Cast aluminum inlet with gasket-matched 64mm compressor opening: The inlet piece matches the turbocharger compressor housing at 64mm ID and transitions smoothly into the larger titanium crossover pipe.
• 80mm OD / 78mm ID titanium crossover pipe: This is the largest inlet pipe available for the FL5. Titanium is lightweight and handles sustained heat cycling in the engine bay.
• No ECU calibration required: Install and drive. No retune or recalibration needed.
• Direct bolt-on fitment, all 2023+ FL5 variants: Fits every FL5 Type-R, including RHD and international models. Works with all factory fitment turbochargers.
• High-temp 4-ply silicone couplers and 304 stainless steel clamps: Three couplers and seven interlocking worm clamps are included. Built for sustained high-temp use.

Is this compatible with the stock intake?

No. This kit is only compatible with the PRL High Volume Intake. It will not work with the factory airbox or other aftermarket intakes.

Do I need a tune after installing this?

No. PRL confirms no ECU calibration is required.

Will this fit RHD or international FL5 models?

Yes. PRL lists fitment for all 2023+ FL5 variants, including right-hand drive and international models.

What is included in the kit?

One cast aluminum inlet piece, one 80mm OD titanium inlet pipe, three high-temp 4-ply silicone couplers, and seven 304 stainless steel interlocking worm clamps.
