Ruthless Racing SEA-DOO Carbon Fiber Rear Air Intake Kit:" The rear air intake kit provides direct, high-volume air to your supercharged engine, resulting in significantly improved acceleration and top speed. It replaces the restrictive stock air box with a 4-inch Marine Grade K&N air filter for easy installation and a clean look, giving you access to your engine compartment."
Ruthless Racing Pitch Solas 161mm 3-blade Concord Impeller: Increases low-end thrust and top-end speed on Sea-Doo 300 HP PWCs. Constructed of high strength stainless steel, Solas Impellers feature a polished hub and exclusive hub-end water seal for reduced cavitation.
KELFORD SEA-DOO Titanium valve retainers and Rocker Bolts: Lightweight and add additional spring tension to the valve spring for more control in higher RPM applications. Rocker bolts are one-time use and need to be replaced.
KELFORD CAM SEA-DOO Billet Racing camshaft: This camshaft delivers unbelievable acceleration by increasing torque and horsepower, resulting in a gain of 450 - 550 RPM and 4-6 MPH. It is excellent for recreational or high-performance applications.
Ruthless Racing SEA-DOO 300 Open Loop Cooling Kit: Our Sea-Doo 230/300 Open Loop Cooling Kit dramatically reduces engine operating temperatures for improved performance and reliability. It includes an adjustable water flow regulator for optimum temperature control. The original closed-loop system quickly becomes heat-soaked in high-performance applications. The open-loop system increases cooling efficiency via a steady supply of cool external water.
RUTHLESS SEA-DOO 4-TEC 4-BOLT SUPER PUMP SEAL (Launch Pump Seal):
PERFECT FOR LAUNCHING 🚀 ZERO CAVITATION
These upgraded performance seals replace the weak OEM seal that often fails in performance applications, providing better acceleration and reduced cavitation.
ARP SEA-DOO 1503/1630 CYLINDER HEAD STUD KIT:
"An ultra-high-strength cylinder head stud kit is essential when upgrading internal components on your high-boost Sea-Doo engine. These studs are precision-machined from premium grade 8740 alloy and heat-treated to exacting tolerances, resulting in dramatically increased reliability and ease of maintenance."
Ruthless Racing Intake Girdle : Secures the intake from coming apart as the 2 pieces are glued together. This goes over the 2 pieces and holds like a big clamp Kit provides added strength to the Sea-Doo 1603 Rotax engine 325 hp intake manifold. The billet aluminum bracket clamps around the side of the manifold easily without drilling or grinding of the stock manifold, providing extra support to the joint that is known to split under higher boost pressures on modified craft. Anodized to prevent corrosion and includes stainless hardware.
RUTHLESS RACING Sea Doo 325 Intake Manifold Bushing & Seal Kit ( P2282 )
This upgrade addresses the common issue of boost leaks in 325hp Sea-Doo engines. The original design of the bushing and seal often leads to leaks between the intake manifold and the cylinder head. These leaks can reduce performance and may even trigger a fault code (P2282) in more severe cases. Our kit includes precision-machined aluminum bushings that deliver the correct clamping force, along with new manifold seals specifically designed for this application. The installation is straightforward, ensuring optimal performance for both stock and modified crafts.
