MOCW 3-piece ignition coil stick set is a direct-fit replacement designed to restore reliable spark delivery on Sea-Doo 4-TEC jet skis and boats compatible with OEM 420-664-020.

If your Sea-Doo is showing intermittent misfires, weak acceleration, or rough idling, a worn ignition coil stick can be the culprit.

The package includes three sticks, and MOCW backs the set with a 12-month warranty for added peace of mind.

Which Sea-Doo models and years will these coil sticks fit?

These ignition coil sticks are specified to match most Sea-Doo 4-TEC applications across many model years, including common GTX, RXT, RXP, GTI, GTS, GTR and WAKE variants. Always compare the OEM number and the physical connector to your existing coil before ordering to ensure a precise match.

• Designed for 4-TEC jet boats and watercraft spanning early 2000s to mid-2010s models.
• Covers GTX 130–260, GTI/GTS/GTR series, RXT/RXP families, WAKE and LIMITED editions where 420-664-020 applies.
• Fits both naturally aspirated and supercharged 4-TEC engine configurations listed by Sea-Doo in the fitment table.

How straightforward is the installation process?

Installation is typically a direct replacement: remove the old coil sticks, clean the mating surfaces, and plug the new pieces in. No special tools are generally required, but careful handling and a clean work area will reduce the risk of damage to connectors and seals.

• Remove old coil sticks and wipe away grease or adhesive residues before seating new sticks.
• Check connector seating and boot alignment to avoid poor contact or arcing.
• Tighten any retaining hardware per Sea-Doo torque specs and test-start before reassembling covers.

What should I check before buying to avoid fitment issues?

Confirming compatibility will save time and returns: verify your Sea-Doo’s year/model and cross-reference the OEM part number 420-664-020 or related numbers. Inspect the existing coil stick’s plug shape, boot length, and electrical connector style to ensure the replacement matches physically.

• Compare your OEM part number (e.g., 420-664-020) against the replacement listing.
• Measure boot length and confirm connector pin pattern matches your unit.
• Note engine variant (standard, limited, supercharged) because application details can differ by year.

Who is this for? This MOCW 3-piece ignition coil stick set is intended for Sea-Doo owners, marine mechanics, and DIY enthusiasts who need an affordable, OEM-compatible replacement for worn or failing ignition coils on 4-TEC engines. It’s a practical option if you’re experiencing spark-related performance issues or performing scheduled ignition maintenance on GTX, GTI, RXT, RXP, GTS, GTR, or WAKE models listed in the fitment. By verifying part numbers and checking the connector and boot fit, you can install this set quickly and get back on the water with improved ignition reliability.
