                  A:

                  Bosch Iridium spark plugs are engineered for high performance and long life, using the best in original equipment 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. 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. 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 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. This all results in improved cold starts and resistance to fouling, giving you longer lasting performance and peace of mind.

              • Q:

                what is the torque for installation of these plugs on a 2004 pontiac grand prix gtp?

                  A:

                  The torque specifications of spark plugs on your 2004 Pontiac Grand Prix GTP should be 28NM. However, I would suggest you to refer your vehicle owner's manual for the exact torque specifications to avoid intermittence.
