Product Details

The DENSO 3085 is a standard spark plug engineered to deliver reliable ignition performance for a wide range of vehicles. This plug features DENSO's innovative U-Groove ground electrode design, which creates a larger flame kernel and improved spark exposure to the air/fuel mixture.

Key Features:

  • U-Groove ground electrode design for enhanced ignitability and more complete combustion
  • Improved fuel efficiency through better flame propagation
  • Reliable cold-start performance in various weather conditions
  • Durable construction for extended service life
  • Standard resistor design to prevent electromagnetic interference

DENSO's U-Groove technology concentrates the spark at the center of the combustion chamber, promoting faster flame growth and more efficient engine operation. This design helps maximize power output while reducing emissions and fuel consumption.

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!

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.
