Works Connection 24-590 Blue Engine Plug Set 2009-2026 Yamaha YZF/WR/YFZ

Stop settling for tired, plastic OEM parts that fade and round off over time. The Works Connection 24-590 Engine Plug Set is the ultimate Race Ready upgrade for your Yamaha, providing a secure, leak-proof seal while adding a factory-level aesthetic to your motor. At Moto-House MX, we know that championship-winning bikes are built on attention to detail, and these precision-fit plugs ensure your timing marks stay protected and accessible through every moto.

Engineered for maximum durability, these plugs are CNC-machined from aerospace-grade 6061 T-6 aluminum right here in the U.S.A. Before receiving their vibrant blue anodized finish, each piece is polished to a mirror shine, resulting in a brilliant look that stands out in the pits. Designed for a simple, positive installation using a standard Allen wrench, this set replaces your stock plugs with a component that is as tough as the Central Florida terrain.

Frequently Asked Questions

Will these plugs fade over time with engine heat?
No, the high-quality anodizing process combined with the initial mirror polish ensures the color remains vibrant even under high-temperature racing conditions.

Do I need special tools to install this set?
Installation is straightforward and only requires a standard Allen wrench, providing a much more "positive" and secure feel than the stock plastic slots.

Are replacement O-rings included?
This set is designed to replace the plugs themselves; we recommend inspecting your stock O-rings or grabbing a fresh set from Moto-House MX during installation for the best seal.
