The NGK TR7IX is an iridium-tipped spark plug sold in a box of four. Its fine-wire iridium center electrode and tapered cut ground electrode are built for strong ignitability, easy starting and crisp throttle response, and iridium resists fouling and wear better than platinum. It suits performance-minded owners and is a direct replacement for the listed Cadillac STS-V and XLR-V applications. Against standard platinum plugs it offers longer service life and sharper response; NGK's own Ruthenium HX line is the step up if you want the longest-lasting option.

Owners of the listed Cadillac V models report smooth idle, clean starts and crisp throttle response after fitting these plugs. Most praise the build quality and longevity of the iridium tip. A few note that the plugs must be gapped and torqued correctly to avoid misfires.
The NGK Iridium IX spark plug (TR7IX) is made for performance-minded drivers. It is designed to deliver acceleration, fuel efficiency and durability. It also offers high ignitability and resists fouling.
The center electrode is a fine wire made of iridium alloy. Iridium is six times harder than platinum, and its very high melting point suits today's engines. The ground electrode has a tapered cut, which improves starting, idling and throttle response.
