Product Details

The NGK 3142 (GR45GP) G-Power Platinum spark plug is a fine-wire platinum-tipped replacement plug. It is a lower-cost alternative to double precious metal plugs, and an upgrade over OE nickel alloy plugs. The platinum center electrode helps with durability, fuel efficiency, lower emissions and consistent starting. NGK is a leading OE spark plug supplier, and this plug carries that reputation for quality and reliability.

Key Features:

  • Fine-wire platinum center electrode for durability and a stable spark
  • Trapezoid-cut ground electrode reduces quenching for faster starts and more responsive acceleration
  • Copper core helps remove heat from the firing end
  • Pure alumina silicate ceramic insulator for strength and heat transfer
  • Trivalent metal plating gives anti-corrosion and anti-seizing protection
  • Corrugated insulator ribs help prevent flashover
  • Triple seals prevent leakage
  • Resistor design (approx. 5,000 ohm) helps suppress radio-frequency interference

Autoplicity had the item I wanted at a cheaper price than anybody online or in stores. They didn't have the item in stock, but they were very informative as to the status of my item. They have shown unheard of customer service via email since the inception of my order. I will definitely do business with them 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.

Autoplicity got my air filters shipped next day after I placed my order. Cheap prices, and good customer is what they stand for. I will definitely be looking at their site in the future for my car needs. <br>

Easy store to navigate through and had all the info.

Received the order in 3 business day. Price was the best. Tried the VIAIR 400p that I order and found it to me my expetations.

Processed and shipped fast. I was a little upset with them shipping my Eibach springs in the Eibach box, and not repackaging it. Everyone could see the box, and knew what was in it. But this will not stop me from ordering again.
