Product Details

The NGK 4536 V-Power spark plug (XR45) is a nickel alloy, resistor-type spark plug. It is designed to match or equal original equipment and gives better ignitability than a standard nickel plug. The V-cut center electrode and concave ground electrode help the engine start quickly and idle smoothly. NGK is a major OE spark plug supplier in North America.

Key Features:

  • V-grooved nickel alloy center electrode places the spark closer to the air/fuel mixture and lowers ignition system voltage requirements
  • Solid copper core for heat dissipation, conductivity and a wide heat range
  • High-grade alumina silicate ceramic insulator for dielectric performance
  • Cold-rolled threads help prevent cross-threading and cylinder head damage
  • Trivalent metal plating resists corrosion and seizing, so installation and removal are easier
  • Resistor design

Specifications:

  • Manufacturer part number: 4536 (NGK plug number XR45)
  • Thread diameter: 14 mm
  • Reach: 0.375 in
  • Seat type: Gasket seat
  • Hex size: 13/16 in
  • Heat range: 4
  • Pre-gap: 0.060 in
  • Center electrode: Nickel tip with copper core
  • Terminal: Non-removable nut
  • Insulator: Ceramic

This plug works best in engines that came with OE nickel alloy plugs. NGK does not recommend it for engines with factory precious metal plugs.

Fast Shipping. Good packaging. Very good pricing. Will shop from again.

Great price and received item in a timely and in great condition. Will definitely shop here again!

Excellent Service! Product shipped out the day after being processed and was sent via overnight delivery. Autoplicity also offered the lowest cost available for the product online.

After searching for the best prices for the product that I wanted, I ended up with Autoplicity. I quickly got a response that my product has just been shipped and I am very impressed that Autoplicity is giving me an incentive to write a review on them. This tells me that this company is very concerned with the satisfaction of their customers. I am currently waiting for the order to arrive, but so far, I am extremely confident and happy with Autoplicity!

Thanks be getting more later

Customer Care took care of my return and refunded the shipping after there was some order confusion. Thank you for taking care of everything!

Wow that was fast. I ordered a Pertronix Ignitor conversion kit. Not only were they by far the lowest price I could find, they shipped within hours of submitting the order. I got the shipment in less than 24 hrs, even though I ordered ground shipping. I was a little bummed that they did not offer free shipping, as I am used to with other online places, but with their fast turnaround, I am not begrudging it. Sure it might have been because they have a warehouse nearby, but it was still unexpectedly impressive. The part arrived and looks like it all there and should be good to go. <br><br>I can't vouch for their customer service, but so far I am pleasantly surprised.
