Product Details

The DENSO 3431 is a premium iridium spark plug engineered to deliver exceptional performance and extended service life. Featuring an ultra-fine iridium center electrode, this spark plug provides superior ignitability and durability compared to conventional copper or platinum plugs.

Key Features:

  • Iridium center electrode for maximum durability and longer service intervals
  • Enhanced ignitability for improved fuel efficiency and reduced emissions
  • Manufactured to strict OE performance, durability, and emissions standards
  • Superior resistance to fouling and pre-ignition
  • Designed for long-life performance in demanding conditions

DENSO's iridium spark plugs utilize advanced materials and precision manufacturing to ensure consistent performance throughout their extended service life. The iridium construction allows for a smaller center electrode diameter, which requires less voltage to fire while providing a more focused spark for complete combustion.

Excellent service

Awsome!

First time shopper. I will definitely be ordering from you guys again. Quite impressed with your pricing and the super fast shipping. Thank you!!

Item came fairly fast, no issues.

Quick and easy and great prices, as always.

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.

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.

Had the absolute best price for a bike carrier. Quick shipping, lots of email feedback so you know what's happening to your order. Highly recommended! AAAAA++++++++++++

Just what you want from a merchant but don't expect; fast, courteous service and attention to the details of your order. I'm a happy consumer. Thank you, Autoplicity. I'll be back.

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.

Easy and fast. Order arrived very fast. Thanks.
