Sea-Doo 230 Intake Kits: 1630 ACE Performance Upgrade

The Sea-Doo 230 platform sits in a strategically interesting spot in the BRP lineup. It's the entry into the supercharged 1630 ACE family — the same engine architecture that powers the 300 HP RXP-X and the 325 HP top trims — running a smaller pulley, a lower boost target, and a different fuel calibration to land at the 230 HP number.

Translation: the engine has headroom. The pulley, the airbox, and the calibration are the limiters, not the hardware. A **Sea-Doo 230 intake** is the single highest-ROI mod on this platform because it removes the most expensive restriction (airflow) for the lowest dollar cost and the lowest risk.

This page covers exactly which 230-platform crafts are affected, what changes after a real intake swap, how the GT40Marine intake compares to the rest of the market, and how to choose between the cold air kit and the shorty filter.

Which Sea-Doo crafts use the 230 HP designation

Sea-Doo's 230 HP rating appears across multiple hulls, all sharing the same 1630 ACE engine in 230-spec calibration:

• **RXP-X 230** — the performance hull in the 230-HP trim. Same body as the RXP-X 300 / 325; different pulley and tune.
• **GTI SE 230** and **GTI Limited 230** — recreation-leaning hulls with the 230 HP powerplant.
• **Wake Pro 230** — towing-focused, same 230 HP block, longer hull.
• **Fish Pro Trophy / Sport 230** — fishing platform on the 230 HP variant of the 1630 ACE.
• **GTX Limited 230** — touring-grade hull with the 230 HP calibration (model-year dependent).

If your Sea-Doo is 2018 or newer and the spec sheet says **230 HP**, you're on the 1630 ACE. A Sea-Doo 230 intake from GT40Marine is built for this exact engine.

If your craft says 300 or 325, jump to our [Sea-Doo 300 cooling kit](/learn/sea-doo-300-cooling-kit) and [titanium exhaust](/learn/sea-doo-titanium-exhaust) pillars — different power band, different priority order.

What a 230 intake does to a 1630 ACE

The OEM 1630 ACE airbox is a sealed plastic enclosure with a paper filter and a long, narrow inlet snorkel routed through the engine bay. It's designed to pass BRP noise compliance and water-rejection testing. It's not designed to maximize airflow into the supercharger.

A real Sea-Doo 230 intake changes three things measurable on a calibrator's logging tools:

**Reduces inlet restriction across the boost curve.** The OEM snorkel and filter assembly create pressure drop the supercharger has to overcome. An open intake or a high-flow cold air kit drops that drop. Net effect: the boost the supercharger actually delivers to the intake manifold comes closer to the boost it would deliver in free air.

**Lowers intake air temperatures under sustained WOT.** In a sealed PWC engine bay, post-supercharger intake temperatures climb fast. A cold-air-routed intake feed pulls cooler ambient air from a hull vent, holding IAT closer to lake-water temperature under load.

**Improves throttle response in the 30–70% pedal range.** The OEM airbox lid creates a phase lag between throttle blip and supercharger spool. A direct-mount or short-path intake tightens that response.

The combined effect on a stock 230 platform is the difference between a craft that feels strong and a craft that feels alive — sharper hookup off the line, more confident mid-range pull, and a clearer top-end runout.

GT40Marine's two Sea-Doo 230 intake options

We make two intakes for the 230 platform. They solve different problems.

**GT40Marine Cold Air Intake (GT-10001 ACE variant).** Carbon fiber housing, cold-air-routed feed from a cooler hull zone, premium filter media. Sealed-housing design keeps water out, holds inlet temps consistent under heat-soak, and looks the part in a clean engine bay. Best choice if you want the gain plus thermal stability over long sessions.

**GT40Marine Shorty Power Filter Intake (GT-10006).** Open-architecture short barrel filter mounted directly to the supercharger inlet. Maximum airflow, maximum induction noise, minimum routing. Best choice for builders who already have the rest of the stack and want the most permissive airflow available.

Comparison: the Sea-Doo 230 intake market

The 230 intake space is crowded. EVP, RIVA, 4-Tec Performance, and a handful of smaller shops all build legitimate parts. Where they differ is materials, routing strategy, support model, and price.

The honest read: every brand on this table makes a Sea-Doo 230 intake that will improve over OEM. The differentiation is materials choice, the price you pay for the badge, and whether you want a dealer-routed support model or direct manufacturer contact.

Where GT40Marine is positioned: premium materials at the price point where most of the market sits one tier above. Direct-to-customer fulfillment from the manufacturer. Native compatibility with the rest of the GT40 stack if you scale to a Stage 2 or Stage 3 build.

When the 230 intake should be your first mod (and when it shouldn't)

**Buy the intake first if:** your 230 craft is otherwise stock or near-stock, you want a single-component upgrade that audibly and visibly changes the boat, and you have a calibrator lined up for a Stage 1 tune. The intake is the substrate for everything else.

**Buy the intake second if:** you already have a worn or original filter element and an unmodified airbox. Drop in our high-flow replacement filter first as a $40 step, ride for a season, then upgrade the full intake. Some buyers split the investment that way.

**Skip the intake** if your craft is brand-new and under warranty for the first 90 days. Get the breakage out of the way on factory hardware, document the boat is healthy, then start the build with the intake.

Pairing the 230 intake with the rest of your stack

A Sea-Doo 230 intake on its own is a meaningful step. Pair it with the other GT40Marine 230-platform parts and the value compounds.

**Catch can breather (GT-11002).** A high-flow intake without a quality breather catch can will eventually puddle oil mist into the intake tract on a supercharged 4-TEC or ACE. The catch can keeps the intake clean and the supercharger seals healthier over time.

**Open loop cooling.** If you ride aggressively in warm water, the [GT40Marine open loop cooling kit](/learn/sea-doo-open-loop-cooling) keeps coolant temperatures in the window where the ECU won't pull timing. Intake gains are real but evaporate the moment the ECU starts protecting the engine from heat.

**Ribbon delete kit.** The factory ribbon plays a role in air management and noise but introduces restriction. A [GT40Marine ribbon delete kit](/learn/sea-doo-ribbon-delete-kit) pairs cleanly with the cold air intake to remove that restriction and clean up the engine bay.

**ECU calibration.** This is the multiplier. Stock fuel and timing tables are conservative. A calibrator-written map tuned to the new airflow releases gain that the hardware on its own cannot.

Install considerations specific to the 230 platform

The 1630 ACE engine bay is tighter than the older 1503 4-TEC bay. Two practical notes:

The supercharger inlet coupler on the 1630 ACE uses a clamp pattern that is unforgiving of misalignment. Take the time to seat the intake square to the inlet before tightening; a skewed mount can pinch the silicone and leak boost.

The cold-air-feed routing on the GT-10001 ACE variant runs near the front of the engine bay. On hulls with aftermarket steering components or stereo amplifier installs in that zone, dry-fit the routing before committing. Most installs are clean; a small number need minor cable management to clear.

We don't publish specific torque values for the supercharger inlet clamp, the throttle-body coupler, or the intake mounting hardware on this page. Those values come from BRP's service manual or from our engineering team when you contact us. A wrong number on a boost-side clamp is the kind of mistake that costs a supercharger.

Frequently asked questions

Bottom line: which Sea-Doo 230 intake to buy

If you ride hard in warm water for long sessions and want the thermal stability of a routed cold-air feed → **GT40Marine Cold Air Intake (GT-10001 ACE)**.

If you've already built the stack (catch can, OLC, exhaust) and you want maximum airflow with no compromise → **GT40Marine Shorty Power Filter (GT-10006)**.

If you're not sure yet → start with the cold air intake. It's the most forgiving choice and the easier resale if you ever move on from the boat.
