Product Details

The NGK 3653 Laser Iridium spark plug delivers premium ignition performance with advanced iridium technology. Featuring a laser-welded iridium center electrode, this spark plug provides superior durability and consistent spark intensity for improved engine efficiency.

Key Features:

  • Laser-welded iridium center electrode for maximum durability and wear resistance
  • Fine wire design concentrates spark energy for improved ignitability
  • Trivalent metal plating provides superior anti-corrosion and anti-seizing properties
  • Corrugated ribs prevent flashover and improve ignition reliability
  • Triple gasket seal eliminates combustion gas leakage
  • OE-quality construction meets or exceeds original equipment specifications

NGK Laser Iridium spark plugs are engineered to provide extended service life, better fuel efficiency, and smoother engine operation compared to conventional copper plugs. The ultra-fine iridium tip requires lower voltage to fire, reducing stress on the ignition system while delivering a more powerful spark.

We ordered the 63 Quart ARB Fridge Freezer and we are very pleased with Autoplicity. The order process on the website was quick and easy. The item was shipped out the next day and we received it within one week. This particular item has been difficult to find and we were very pleased with Autoplicity's pricing and shipping. Thank you for the great service!

Excellent e-merchant. Awesome service, great products and super low prices !!!

Fast service, and helpful staff.

Good store to deal with.<br><br>Will purchase from them again.

Autoplicity had the exact part I wanted at the best price upfront with no gimmicks or hidden conditions. Prompt shipping at a fair price. Simply excellent!

Fast shipping! would buy from again for sure! Great product at the best price that I could find!

Very satisfied

I had been searching many sites for a better price on shocks for my 1999 Ford Explorer, upon finding Autoplicity the savings was 13.00 cheaper than all others. I instantly made the purchase. wish i had knew about them before I purchased the other items for my truck. will return as a customer .

Lowest price online. Shipped about an hour after I placed the order. Many payment options make it easy. Haven't been able to track my package but I'm assuming its too soon, I'll try again soon.

I placed an order and 2 days later it was at my door!!! Very fast shipping and easy to navigate website! I would definitely recommend this site to all my friends. Keep up the great job!
