Product Details

The NGK 4421 V-Power spark plug (BKR4E) is a resistor-type replacement spark plug built to OE-equivalent standards. Its V-cut nickel alloy center electrode and concave ground electrode increase ignitability. They also lower the voltage the ignition system needs, which helps support smooth starts and consistent combustion.

Key Features:

  • NGK part number 4421, plug number BKR4E
  • Nickel V-groove (V-cut) center electrode with a copper core, 2.5mm
  • Standard nickel ground electrode, J-gap configuration, single ground electrode
  • Projected insulator, ceramic insulator material
  • Heat range 4
  • Built-in resistor, 5k ohm
  • Thread size M14-1.25 with 19mm (3/4 in.) reach
  • 5/8 in. (16mm) hex size
  • Gasket seat, with gasket included
  • Non-removable terminal nut
  • Trivalent metal plating for anti-corrosion and anti-seizing properties, for easier installation and removal

Installation Notes: Recommended torque is 18-25.3 lb-ft in cast iron heads and 18-21.6 lb-ft in aluminum heads.

NGK is the largest OE spark plug supplier in North America. The V-Power line gives dependable, OE-quality performance and a longer service life than standard plugs. It suits routine replacement of a worn spark plug.

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.

Good website

Beat price. Super fast processing and shipping. Will shop there again.

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>

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.
