Product Description
Bosch 9604 OE Iridium Finewire Spark Plug, Pack of 1: Automotive. Other manufacturers use pulse welding or resistance welding, which over time can introduce cracks and faults into the plug sooner, reducing the plug's performance. Bosch Iridium spark plugs are engineered for high performance and long life, using the best in OE technology. Bosch Iridium's ultra-fine wire center electrode design improves ignitability, lowers voltage demand, and delivers up to 4x longer service life versus standard copper core plugs. The laser-welded iridium-platinum alloy inlay on the ground electrode resists cracking and potential loss for improved durability. Continuous Wave laser-welding yields a uniform electrode surface that resists cracking and corrosion Race-proven Bosch spark plugs are the result of over 100 years of innovation, engineering and relentless testing. What Bosch learns on the track and working side by side with original equipment vehicle manufacturers translates into the advanced technology, materials, and processes that produce spark plugs of superior performance and durability. When you need power, acceleration and throttle response, install a set of Bosch spark plugs. Tapered Ground Electrode The tapered ground electrode design reduces flame shrouding and improves flame kernel growth for better combustion and more power. Continuous Laser-Welded Center Electrode 360 degrees of continuous laser welding fuses the iridium firing pin to promote durability and long life. Bosch uses a continuous laser weld to create a smooth firing pin surface that better resists cracking and increases durability. Up to 4x Longer Service Life Bosch Iridium yields up to four times the service life compared to conventional copper core plugs, thanks to improved manufacturing techniques like continuous laser welding, yttrium-enhanced ground electrodes, and an iridium-platinum tip.
