Product Details

The DENSO 3493 is a premium iridium spark plug engineered to deliver exceptional ignition performance and extended service life. Featuring a 0.4mm iridium center electrode, this plug provides superior ignitability and durability compared to traditional copper or platinum plugs.

Key Features:

  • Ultra-fine 0.4mm iridium center electrode for improved throttle response and fuel efficiency
  • Nickel-plated housing resists corrosion and seizure for easy removal
  • Ribbed insulator prevents flashover and misfires in high-temperature conditions
  • Trivalent metal plating provides superior anti-corrosion and anti-seizing properties
  • Manufactured to OE specifications for performance, durability, and emissions compliance

DENSO iridium spark plugs are designed to provide reliable ignition under extreme conditions while reducing maintenance intervals. The iridium construction allows for a smaller electrode diameter, which requires less voltage to fire and creates a more focused spark for improved combustion efficiency.

Great Prices and Fast Shipping!

Recently placed an order for some head studs for my car. They were much less expensive at autoplicity than elsewhere. I was surprised I hadn't heard anything back after a couple days, but was reassured that orders are processed within 24 business hours (3 days), not 24 hours (which I misread in my confirmation email). Just received a shipping confirmation with a tracking number today.

This was an excellent transaction! I ordered parts on Sunday and they arrived tuesday afternoon. Low price, no fuss and super fast. Thanks Autoplicity..........

great so far

Easy.....

thanks
