Product Details

The DENSO 3373 is a premium iridium spark plug engineered for extended service life and superior performance. Featuring an ultra-fine iridium center electrode, this spark plug delivers consistent ignition efficiency while resisting wear far longer than conventional copper or platinum plugs.

  • Iridium center electrode provides exceptional durability and longevity
  • Superior ignitability for improved fuel efficiency and engine response
  • Manufactured to strict OE performance, durability, and emissions standards
  • Long-life design reduces replacement frequency and maintenance costs
  • Precise heat range control prevents pre-ignition and fouling

DENSO's iridium technology ensures reliable cold starts, smoother acceleration, and optimal combustion across a wide range of operating conditions. This spark plug is designed to meet or exceed original equipment specifications for vehicles requiring iridium spark plugs.

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.

Didn't see military/LEO discount =(

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.

good price, quick and easy ordering

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.
