Product Details

The DENSO 3066 is a standard copper core spark plug designed to deliver reliable ignition performance for a wide range of gasoline engines. This spark plug features DENSO's proven U-Groove ground electrode design, which enhances ignitability and promotes more complete combustion for improved engine efficiency and fuel economy.

Key Features:

  • U-Groove ground electrode design for superior spark exposure and ignitability
  • Copper core center electrode for excellent heat dissipation and conductivity
  • High-grade insulator material resists thermal shock and electrical breakdown
  • Trivalent metal plating provides superior anti-corrosion and anti-seizing properties
  • OEM-quality construction meets or exceeds original equipment specifications

DENSO is a leading original equipment manufacturer of spark plugs for many major automotive brands. The U-Groove design creates a larger, more robust spark kernel compared to conventional spark plugs, resulting in smoother idle, better throttle response, and reduced emissions. Ideal for standard replacement applications requiring reliable performance and durability.

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.

Best price. Looks accredited and secure. Didn't state free shipping then added it later in process. Your shipping cost only 60¢ more than "free" shipping costing $9.95 Thanks.

Found Autoplicity through price searching. Best price, easy to navigate site, quick service. Bookedmarked for future use!

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.
