The Spark Plug BR9HS-10 (10/Pack) (86-4551) provides greater ignitability, increased throttle response, and superior anti-fouling for the performance enthusiast. The laser-welded small Iridium tip ensures long-term endurance and a steady spark, while the tapered ground electrode lessens the influence of electrical quenching. A longer insulator nose prevents fouling, corrugated ribs on the insulator prevent flashover, and a triple gasket seal prevents combustion gas leakage. Spark Plug BR9HS-10 (10/Pack) (86-4551) has a high melting point, which makes it resistant to heat and electrical wear, making it excellent for today's high-performance engines.
Key features:
- Trivalent metal plating
 - improves anti-corrosion and anti-seizing properties.
 - Corrugated ribs help avoid flashover.
 - Isolator composed of pure alumina silicate ceramic, which offers excellent heat transfer and strength.
 - The copper core helps to dissipate heat.
 - Triple seals keep leakage at bay.
 - Ultrafine wires help to increase ignitability and performance.
