Fitment. Don't let fouled or inferior plugs rob your C4, C4 ZR-1, or C6 of valuable power - or rob you of money at the pump. If you're replacing the plugs in your 92-95 LT1, 93-95 LT5, or 07 LS2, platinum plugs are probably one of your top choices - but now thanks to NGK, they're affordable, too.
Premium Design. The precision-crafted design of NGK's G-Power Platinum plugs delivers the premium performance of platinum without the premium price. The ultra-fine platinum center electrode is combined with a sharp pointed ground electrode to deliver superior ignitability and performance. You'll enjoy stronger starts, better acceleration, and overall cleaner combustion for more power and better fuel efficiency.
Expensive Materials, Competitive Price. NGK is proud to offer these 100% pure platinum plugs at a very affordable price. The unique properties of platinum that make it so desirable have been maximized by NGK's engineers - and the result is a plug that provides all the power, performance, and quality you've come to expect at a very competitive price.
Long Life. The beauty of platinum is that it performs to a higher standard than other metals - burning cleaner and lasting longer than traditional materials.
OEM Quality. NGK is one of the premier manufacturers of spark plugs worldwide. All NGK plugs are made with a solid copper core, to ensure greater spark and heat transfer. Plus they use a triple gasket sealing process to eliminate the potential for combustion gas to leak back through the shell - superior to other manufacturer's one or two shell design. And their double dipped zinc chromate shell is designed for maximum corrosion and rust resistance.
