Product Description

Designed specifically for the performance enthusiast, Iridium IX offers extreme ignitability, improved throttle response and superior anti-fouling. The 0.6mm laser welded fine iridium tip ensures high durability and a consistently stable spark and the tapered ground electrode minimizes electrical quenching effect. Longer insulator nose prevents fouling, the corrugated ribs on insulator prevents flashover, and a triple gasket seal eliminates combustion gas leakage. Iridium alloy has extremely high melting point, giving it high durability to heat and electrical wear, perfect for today's high-performance engines. Trivalent metal plating has superior anti-corrosion and anti-seizing properties.

My Honda Foreman 500 used to be very cold natured until I put this plug in. It now doesn't need to be started by choking much of the time and when I do have to choke the engine, it can be unchoked after starting where I used to run with choke for a while before it would stay running. Great plug.

I noticed people are buying Permatex anti-seize along with these NGK iridium plugs. According to the NGK website, anti-seize lubricant should not be applied to the threads, since they have a special plating that resists seizing without the use of compounds. Also, the threads should be dry during installation, since use of anti seize can cause an increase in the torque applied, thereby creating the possibility of over-tightening.

I have four of these plugs in my 2002 Corolla with stock ignition and they are Fantastic! I just checked them after 11,636 miles and there is no electrode erosion on these plugs (Checked plugs with a wire gap tool)! I would suggest to everybody who changes their own spark plugs to at least check them around every 12,000 miles or once a year (even if they are long life plugs, reading the plug will let you know about any potential issues with the engine). If your looking to put better plugs in your Corolla, NGK Iridium IX is an excellent choice. Fuel economy on the Corolla does slightly increase ~1% but every little bit counts! Another pointer is to drive conservatively and (if you can) anticipate traffic flow, curves, hills and don't ride the brakes - increase your following distance and let the car coast down the road. God Bless and happy trails!
