Product Details

The DENSO 4176 is a standard copper core spark plug designed to deliver reliable ignition performance for a wide range of gasoline engines. This OEM-quality spark plug features DENSO's proven U-Groove ground electrode design, which creates a larger flame kernel for improved ignitability and more complete combustion.

Key Features:

  • U-Groove ground electrode design enhances ignitability and flame propagation
  • Copper core center electrode for superior heat dissipation and electrical conductivity
  • Standard resistor design reduces electromagnetic interference (EMI)
  • Nickel-plated shell provides excellent corrosion resistance
  • Precision-manufactured to strict OEM tolerances for reliable fitment
  • Ribbed insulator prevents flashover and improves durability

DENSO's U-Groove technology features a unique ground electrode design that exposes more of the center electrode to the air-fuel mixture, promoting faster flame front development and more efficient combustion. This results in improved throttle response, better fuel economy, and reduced emissions compared to conventional flat-ground electrode designs.

As a genuine DENSO spark plug, the 4176 meets or exceeds OEM specifications and is engineered for long service life and consistent performance in demanding automotive applications.

Easy, customer-friendly online shopping. I am satisfied.

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.

Lowest prices, great service. Thanks.

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.
