SYKRSS Iridium Spark Plug 41-109 (ILTR6E11) is a six-pack replacement set engineered to restore reliable ignition, better throttle response, and long service life on compatible GM engines.

These SYKRSS iridium spark plugs are designed as direct-fit replacements for a wide range of General Motors vehicles including Chevy Equinox, Malibu, Traverse, Camaro and many Buick, Cadillac, GMC, Saab and Saturn models. Built with an iridium-tipped center electrode, copper core and ceramic insulator, this set aims to match OEM dimensions and electrical characteristics while improving ignition stability and longevity compared with standard plugs. The package contains six plugs and a user manual, and the parts are labeled with OE cross-reference numbers such as 41-109, 12622561, 12681660 and ILTR6E11 for easier fit confirmation.

How do these iridium plugs improve engine performance?

Iridium electrode material offers a smaller, more durable firing tip which promotes a more focused spark and consistent combustion. That can translate to steadier idling, crisper throttle response and potentially better fuel use under normal driving conditions.

• Smaller iridium tip concentrates spark energy for efficient combustion
• Copper core helps with heat transfer for stable operating temperature
• OEM-style design preserves correct gap and thread dimensions for reliable sealing

Are these SYKRSS plugs as reliable as OEM replacements?

SYKRSS plugs are manufactured to meet or exceed OE form, fit and function specifications, using iridium and copper construction and undergoing quality control tests. While performance can vary by engine condition, these plugs are intended as durable, cost-effective alternatives to factory units.

• OE cross-reference numbers included for straightforward replacement
• Manufactured with ceramic insulators and corrosion-resistant plating
• Each plug is tested to ensure stable high-voltage output across operating RPM ranges
