Product Details

The DENSO 4101 is a standard copper core spark plug designed to deliver reliable ignition performance for a wide range of vehicles. This spark plug features DENSO's proven U-Groove ground electrode design that creates a larger flame kernel for improved ignitability and more complete fuel combustion.

Key Features:

  • U-Groove ground electrode design for enhanced spark exposure and better flame propagation
  • Copper core center electrode for superior heat dissipation and thermal conductivity
  • Nickel alloy ground electrode provides durability and corrosion resistance
  • 14mm thread diameter with standard reach for broad vehicle compatibility
  • SAE terminal configuration for secure connection
  • OEM-quality construction meets or exceeds original equipment specifications

The U-Groove design increases the spark area by creating a channel that exposes more of the air-fuel mixture to the ignition spark, resulting in improved engine efficiency, smoother acceleration, and better fuel economy. Ideal for standard replacement applications in everyday driving conditions.

Autoplicity products are much cheaper than anywhere else. I was happy to find a good product for that price. Just waiting for the order to arrive.

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.

Great service. Shipped out the day after I ordered it...plus it was the cheapest of the competition.

Quick, easy, simple

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.
