Product Details

The NGK 5438 Iridium IX spark plug delivers superior ignition performance and extended service life for a wide range of automotive applications. Featuring a 0.6mm iridium center electrode, this plug provides improved throttle response, better fuel efficiency, and more complete combustion compared to conventional spark plugs.

Key Features:

  • Ultra-fine iridium center electrode for concentrated spark energy
  • Tapered ground electrode reduces quenching for improved flame kernel growth
  • Trivalent metal plating provides superior anti-corrosion and anti-seizing properties
  • Corrugated ribs prevent flashover and improve insulation
  • Purified alumina powder insulator provides superior strength and thermal conductivity
  • Copper core aids in heat dissipation for consistent performance

NGK Iridium IX spark plugs are designed to meet or exceed OE specifications, providing reliable ignition in demanding conditions. The iridium construction allows for a smaller center electrode diameter, which requires lower voltage to fire and creates a more focused spark for improved combustion efficiency. Backed by NGK's decades of ignition expertise, the 5438 offers dependable performance for thousands of miles.

Ordered a sling to store my roof rack. There was an issue with the supplier which was quickly resolved by the Autoplicity staff. Great customer service -- most responsive I've ever seen.<br><br>Best prices around.

Im very satisfied with how fast i received my product from Autoplicity! The whole process was hassle free. If you looking for quality product for a great price than i would recommend Autoplicity!

Autoplicity got my air filters shipped next day after I placed my order. Cheap prices, and good customer is what they stand for. I will definitely be looking at their site in the future for my car needs. <br>

Received the order in 3 business day. Price was the best. Tried the VIAIR 400p that I order and found it to me my expetations.

Processed and shipped fast. I was a little upset with them shipping my Eibach springs in the Eibach box, and not repackaging it. Everyone could see the box, and knew what was in it. But this will not stop me from ordering again.

Autoplicity has fast shipping and great prices on quality auto parts. I will use them again soon, I am a very satisfied customer.<br>Thanks Jimmy
