Product Details

The DENSO 3418 Iridium Long-Life spark plug delivers superior ignition performance and extended service life for a wide range of vehicles. Engineered with advanced iridium technology, this spark plug features a 0.4mm diameter iridium center electrode that provides exceptional durability and precise spark generation.

Key Features:

  • Iridium center electrode for extended service life up to 60,000-120,000 miles
  • 0.4mm ultra-fine electrode tip improves ignitability and reduces required voltage
  • Platinum ground electrode enhances durability and wear resistance
  • 360-degree laser welding ensures superior heat dissipation
  • U-groove ground electrode design improves flame kernel development
  • Purified alumina powder insulator provides superior dielectric strength
  • Manufactured to strict OE performance, durability, and emissions standards

DENSO iridium spark plugs are designed to maintain consistent performance throughout their service life, reducing misfires and improving fuel efficiency. The ultra-fine iridium tip requires less voltage to fire, ensuring reliable starts and smooth acceleration even in demanding conditions.

First off, I LOVE my new shipments! These guys had everything at super low prices, and the shipping was phenomenally fast. It's all working great, and imm definitely buying from these guys again.

Great service. fast shiping!

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.

Great service. Shipped out the day after I ordered it...plus it was the cheapest of the competition.

I bought a Motive pressure brake bleeder from Autoplicity. I have been looking around for different prices for quite a while, and their price, even with shipping cost, was the lowest. After ordering, I received a notification of shipment and tracking number. The item arrived well packaged, complete, and intact within a few days. I am looking forward to using it.

Cheap prices, great quality, and fast delivery. Autoplicity will continue to receive my patronage.

Easy and fast. Order arrived very fast. Thanks.
