Product Details

The DENSO 4030 is a standard spark plug featuring advanced U-Groove technology designed to deliver superior ignitability and enhanced engine performance. This spark plug is engineered to provide reliable ignition across a wide range of operating conditions.

Key Features:

  • U-Groove ground electrode design improves flame kernel development for more complete combustion
  • Enhanced ignitability increases engine efficiency and throttle response
  • Standard resistor construction reduces electromagnetic interference
  • Durable construction for reliable performance and extended service life
  • Precision-manufactured to OEM specifications for proper fit and function

DENSO's U-Groove technology positions the ground electrode to optimize the spark gap, allowing the air/fuel mixture to ignite more quickly and burn more efficiently. This design improves cold starting, reduces emissions, and helps maintain consistent engine 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.

I was greatly surprised at how soon I received my order, 3 day early!! I will definitely look here the next time I need parts.

Fast, with great prices. I would definitely buy from Autoplicity again.

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.
