Product Details

The DENSO 4017 is a standard spark plug engineered with U-Groove technology for superior ignition performance. This innovative design features a unique U-shaped ground electrode that creates a larger flame kernel compared to conventional spark plugs, ensuring more complete combustion and improved fuel efficiency.

Key Features:

  • U-Groove ground electrode design for enhanced ignitability and flame propagation
  • Copper core center electrode for excellent heat dissipation and thermal conductivity
  • Nickel alloy construction for durability and extended service life
  • 14mm thread diameter with standard reach
  • Precision-manufactured insulator reduces misfires and provides reliable performance
  • OEM-quality construction meets or exceeds original equipment specifications

DENSO's U-Groove technology positions the spark closer to the air/fuel mixture, resulting in faster flame growth, more stable combustion, and reduced emissions. Ideal for standard replacement applications across a wide range of automotive engines.

Arrived in good working order.

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.

Cheap prices, great quality, and fast delivery. Autoplicity will continue to receive my patronage.

Easy and fast. Order arrived very fast. Thanks.
