The NGK 5281 Racing Plug - R2525-10 is part of the NGK Racing Series, engineered to endure the harshest engine conditions. The fine wire platinum tipped center electrode enhances ignitability, increases durability, and provides superior anti-fouling capabilities. The special insulator nose configuration improves throttle response, while corrugated ribs prevent flashover. Constructed with a pure alumina silicate ceramic insulator, it offers superior strength and better heat transfer. The copper core aids in efficient heat removal, and the triple seals prevent leakage, making this racing plug a reliable choice for maintaining optimal engine performance under extreme conditions.
