Hey Sea-Doo owners! If you're dealing with rough idling, poor performance, or just want to keep your watercraft running smoothly, these fuel injectors are exactly what you need. This 3-pack replaces part numbers 420874834, 420874846, and 006-622, and they work with a ton of Sea-Doo models from 2009 through 2017. We're talking Challenger, GTI, GTR, GTX, RS, RXP, RXT, Speedster, and Wake models - basically if you've got a Sea-Doo from that era, these probably fit. They're direct replacements that deliver the right fuel spray pattern and flow rate your engine needs for optimal performance. Whether you're dealing with specific performance issues or just doing preventative maintenance, having fresh injectors can make a huge difference in how your watercraft runs. The installation is pretty straightforward if you're comfortable working on engines, but if not, any marine mechanic can handle it quickly. These are built to meet or exceed OEM specifications, so you're getting quality parts without the dealership price tag. They help maintain proper fuel atomization, which means better combustion, improved throttle response, and overall smoother operation. If your Sea-Doo has been sitting for a while or you're just noticing it's not running as strong as it used to, new fuel injectors might be exactly what it needs to get back to peak performance on the water.
