PRL Motorsports Titanium Turbo Inlet Pipe Kit - FL5 Type R & DE5 Integra Type S
The inlet pipe feeds the turbo, and the factory FL5 unit chokes it before it even starts working. This is PRL's answer: a cast aluminum inlet transitioning through a titanium crossover pipe, gasket-matched from a 64mm compressor inlet to an 80mm outlet. It's the largest inlet pipe available for the car and flows over 50% more than stock, which turns into quicker spool and more bottom-end power.
Read This First: Requires The PRL High Volume Intake
The most important thing on this page, and it's a hard dependency rather than a suggestion.
This kit only works with the PRL High Volume Intake. It will not work with the factory airbox or another brand's intake, because the inlet pipe is designed to mate specifically to the PRL intake on the upstream side.
So if you don't already have the PRL High Volume Intake, you need it for this to fit. Buy both, or add this to a car that's already running the intake. Confirm what you have before ordering, because this is not a standalone part.
Why The Inlet Pipe Matters
Worth understanding, because it's closer to the turbo than most intake work and that's where it counts.
Air flows from the intake, through the inlet pipe, into the turbo's compressor. If that pipe is restrictive, the compressor is drawing against a bottleneck right at its inlet, which makes it work harder to spin up and limits how much air it can move.
The factory inlet pipe is that bottleneck. Opening it up means the compressor gets a clean, unrestricted supply, which shows up as faster spool and more power down low where the turbo is trying to come alive. On a car people drive hard, that low-end responsiveness is felt constantly.
Over 50% More Airflow
The dimensions tell the story.
The cast aluminum inlet is gasket-matched to a 64mm ID compressor inlet, then transitions through the titanium crossover to an 80mm OD / 78mm ID outlet. That's the largest inlet pipe available for the platform, and it flows over 50% more air than the factory piece.
The gasket-matching matters. A pipe that's large but doesn't match the compressor inlet cleanly leaves a step or mismatch right where flow is most sensitive. Matching it means the transition is smooth from the pipe into the turbo.
Why Titanium
The crossover pipe is titanium, and it's a deliberate choice beyond looks.
Titanium is light, strong, and handles heat exceptionally well, which matters on a pipe sitting close to a hot-running turbo. It also has low thermal conductivity, so it doesn't soak up and transfer as much engine bay heat into the intake air as aluminum would.
And it looks the part. Titanium in an engine bay is a genuine statement, the kind of material that signals a serious build, and it develops character as it heat cycles.
No Tune With The PRL Intake
Paired with the PRL High Volume Intake it requires, no ECU calibration is needed. You're improving airflow into the turbo rather than changing how air is metered, so the tune stays correct.
The kit includes the cast aluminum inlet, the titanium pipe, three high-temp 4-ply silicone couplers, and seven 304 stainless interlocking worm clamps. Everything needed to install it cleanly.

Who Should Grab This
This is for the FL5 or Integra Type S owner who's already running the PRL High Volume Intake and wants the inlet path fully opened up to the turbo. The largest inlet pipe made for the car, titanium construction, over 50% more flow, and quicker spool with more bottom end. Confirm you've got the PRL intake, and finish the path to the turbo properly.
