Product Details

The DENSO 4009 is a standard copper core spark plug engineered to deliver reliable ignition performance for a wide range of gasoline engines. This proven design combines quality construction with dependable operation for everyday driving conditions.

Key Features:

  • U-Groove ground electrode design enhances ignitability and flame kernel development
  • Copper core center electrode provides excellent heat dissipation and thermal conductivity
  • Standard resistor design suppresses electromagnetic interference with vehicle electronics
  • Nickel-plated housing resists corrosion and seizing in the cylinder head
  • 14mm thread diameter with gasket seat
  • Precise heat range engineering ensures optimal performance across operating conditions

DENSO's U-Groove technology creates a larger, more robust spark by optimizing the flame front propagation, resulting in improved combustion efficiency, better throttle response, and more complete fuel burn. This spark plug is designed as a direct replacement for vehicles originally equipped with standard copper core 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.

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.

Quick, secure checkout.

I found it fairly quickly and without much hassle, however i was unsure if it was the part i needed because of lack of details.

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.
