Product Details

The DENSO 3500 Iridium Long-Life spark plug delivers superior ignition performance and extended service life for demanding automotive applications. Featuring an iridium center electrode, this spark plug provides exceptional durability and resistance to wear compared to conventional copper or platinum plugs.

Key Features:

  • Iridium center electrode for extended service life and superior wear resistance
  • Manufactured to strict OE performance, durability, and emissions standards
  • Improved ignition efficiency for better fuel economy and reduced emissions
  • High melting point iridium construction ensures consistent performance under extreme conditions
  • Precision-engineered to meet or exceed original equipment specifications

Easy simple checkout

good site, EASY to use but wrong parts were sent

very easy

So far ... So good

Thank you. Have a Happy New Year!

You have a "glitchy" website. Doesn't work on Chrome and hangs up on Explorer (loading screen).

Hi there, I received a coupon code of: 30offshipping and tried to use it on my order, but when checking out there was no place for code before order was sent. You skipped conformation part of checkout and went straight to the order. That left me without the 30% shipping discount. Your normal shipping was too high and I wouldn't have ordered otherwise.

Great price!!! Great product!!! Fast shipping!!!

The radiator i ordered for my 98 Subaru was an exact fit and was $200 dollars less than the dealership. i would definitely order parts from Autoplicity again.
