Product Details

The NGK 6418 Iridium IX spark plug delivers superior ignition performance and extended service life for a wide range of automotive applications. Featuring an ultra-fine 0.6mm iridium center electrode, this plug provides improved throttle response, better fuel efficiency, and more reliable cold starts compared to conventional spark plugs.

Key Features:

  • Iridium center electrode for maximum durability and longevity
  • Trivalent metal plating for superior anti-corrosion and anti-seizing properties
  • Corrugated ribs prevent flashover and improve ignition reliability
  • Purified alumina powder insulator provides better heat dissipation
  • Copper core electrode enhances heat dissipation and conductivity
  • Triple gasket seal eliminates combustion gas leakage

NGK Iridium IX spark plugs are designed to meet or exceed OE specifications, providing up to 4 times longer service life than traditional copper plugs. The iridium construction allows for a smaller center electrode diameter, which requires less voltage to fire and creates a more focused spark for improved combustion efficiency.

Great cheepest price for what I needed

Smooth transaction & fast delivery. Thanks

would buy from them again

.

I was satisfied with customer service and response and overall friendliness

I was looking for a part for my Mallory distributor at a fair price. I called around to my local speed shops and they all had to order the part, so I went on line. With a little research for the best price here, at Autoplicity. I ordered the part last night and it has shipped 24 hours later. I like that. I have bookmarked Autoplicity so I can use the again. Thanks guys.<br><br>Jim

Have not recieved order yet, but price was good. Will see how long it takes and if I get the right product. Writing this review before arrivial.

Had problems using the search tool so I called direct. They helped locate Air Lift shocks I needed and told me that I.E. browser is sometimes a problem. They were helpful and my items got shipped the next business day.

Definitely the lowest price! Quick shipping, and great communication and follow-through.

Great customer service. There was a glitch in the email system, and when I called them they were very helpful and understanding. I will be doing business with them again in the future.

Autoplicity was a great place to shop. By far the lowest price on the rack that I purchased. Fast shipping and overall very satisfied.<br><br>

Excellent and very quick service. I could not find this product in stock from any other supplier so I kept hunting. I found Autoplicity and from now on they are the first company I will try. Thank you.
