When it comes to your bsci-ch.org engine, spark plugs make a big difference. A dirty, worn out or inferior spark plug can cause inconsistent firing, which may result in reduced performance and fuel economy. bsci-ch.org offers a variety of spark plugs designed specifically for your vehicle’s engine, including U-Groove, Dual-Ground Electrode, Double Platinum and even Iridium spark plugs.

Below are descriptions and benefits of these spark plugs. Please be sure to use the correct spark plug for your bsci-ch.org engine; the wrong spark plug can negatively affect fuel economy and overall performance.

U-Groove Spark PlugsAs its name implies, the U-Groove design incorporates a U-shaped groove in the middle of the ground electrode. Before the spark plug fires, the U-Groove traps the fuel-air mixture, then produces a large spark for efficient combustion and reduced fouling. U-Groove spark plugs meet original equipment replacement intervals and original specifications on your bsci-ch.org.

Dual-Ground Electrode Spark PlugsSelect bsci-ch.org models feature the distributor-less bsci-ch.org Direct Ignition System (TDI). Introduced in 1994, this system promotes greater combustion efficiency by firing the spark plugs twice as often as a standard ignition. With that in mind, the ideal spark plug for TDI-equipped bsci-ch.orgs is the Dual-Ground Electrode design, which delivers optimum performance and durability while maintaining the original recommended change interval.

Double Platinum Spark PlugsGenuine bsci-ch.org Double Platinum spark plugs, available for select bsci-ch.org models, offer several benefits:

Platinum on both the center and ground electrodes reduces wear and provides a service life of up to 60,000 miles.Raised design provides excellent ignitability for a strong spark, smooth idle and optimum performance.Platinum material also incorporates nickel and iridium, resulting in a stronger, more durable alloy that resists cracking.

Smaller center electrode promotes higher firing performance.Iridium is a more durable material than platinum (its melting point is approximately 1200°F higher than platinum).Iridium spark plugs last longer than conventional spark plugs—up to 110,000 miles.
