Product Details

The DENSO 4046 is a standard spark plug engineered with U-Groove technology to deliver reliable ignition performance for a wide range of vehicles. This innovative design features a unique U-shaped ground electrode that creates a larger, more accessible flame kernel compared to conventional spark plugs.

Key Features:

  • U-Groove ground electrode design provides superior ignitability and more efficient combustion
  • Increased flame kernel exposure improves fuel burn efficiency and engine performance
  • Standard copper core construction offers excellent heat dissipation
  • OEM-quality replacement for original equipment specifications
  • Designed and manufactured by DENSO, a leading global supplier of automotive components

The U-Groove design allows the spark to develop more rapidly and spread more effectively throughout the combustion chamber, resulting in smoother idle, improved throttle response, and optimized fuel economy. This spark plug meets or exceeds original equipment standards for reliable, long-lasting performance.

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.

good seller

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.
