PRL Motorsports Silicone Intake Hose Kit (ARDX3-INT-HOSE) - 2019-2025 Acura RDX 2.0T
The factory RDX inlet hose is corrugated, and those pleats disrupt airflow right where the engine is drawing it. This PRL kit replaces it with smooth 4-ply silicone that flows better and sharpens throttle response, and unlike a full intake system it keeps your factory airbox. No tune required, and it's the easy way to open up the inlet without replacing everything.
Works With Your Factory Airbox
Worth leading with, because it's what makes this the accessible option.
Some intake upgrades require replacing the whole airbox or committing to a matching intake system. This isn't one of them. The silicone hose swaps in while keeping your factory airbox, which means a simpler, cheaper job and no dependency on other parts.
It pairs especially well with a PRL drop-in panel filter. The filter replaces the restrictive factory paper element inside your existing airbox, and together the two open up the intake path, from the filter through the inlet hose, without ever removing the box. It's the most flow you can get while staying bolt-on and airbox-friendly.
Why The Pleats Cost You
Worth understanding, because it's the reason this part exists.
Honda uses a corrugated hose because it's cheap and flexes to accommodate engine movement. But those pleats create turbulence. Air moving through a ridged tube tumbles and slows against every corrugation, where smooth walls let it flow cleanly.
On a turbocharged 2.0T, that restriction sits in the inlet path feeding the turbo. Smoothing it out lets the engine draw more freely, which shows up as better throttle response and a small gain in power potential.
Silicone Holds Up Better Too
Beyond flow, 4-ply silicone is simply better material than the factory hose.
It handles the heat of a turbo engine bay better, it doesn't degrade the way rubber and plastic do over years of heat cycling, and it looks considerably cleaner than a corrugated black tube. On a car you're keeping, that's a durability upgrade alongside the flow.
A Complete Kit, Not Just A Hose
This kit includes more than the hose, which is what makes it a clean install rather than an improvised one.
Along with the 4-ply silicone hose and four 304 stainless clamps, it comes with an evap purge assembly and an intake scoop standoff assembly. Those handle the connections and mounting the factory hose managed, so nothing gets left disconnected or hanging when the old hose comes off.
Everything reconnects where it should, which keeps the install straightforward and the result factory-clean.
No Tune, Bolt-On
No ECU calibration required. You're smoothing the path air takes, not changing how it's measured, so the factory tune stays correct. The whole swap is a bolt-on with the included hardware.

Who Should Grab This
This is for the RDX owner who wants the corrugated factory hose gone without replacing the whole intake, and who'd rather keep the factory airbox and add a panel filter than commit to a full system. Better flow, sharper throttle, and a complete kit that reconnects everything properly. Pair it with the drop-in filter, bolt it on, and lose the pleats.
