Product Details

The Fram XS4163 Xtreme Sport Iridium Powersports Spark Plug is engineered for high-performance powersports applications including motorcycles, ATVs, and personal watercraft. Built under the Autolite Xtreme Sport Iridium line, this plug delivers reliable ignition and consistent performance in demanding riding conditions.

Key Features:

  • Iridium center electrode for superior durability and a more focused spark compared to standard copper plugs
  • Fine-wire iridium tip promotes easier firing and improved throttle response
  • Nickel-plated shell resists corrosion and makes installation and removal easier
  • Ribbed ceramic insulator prevents flashover and provides added insulation integrity
  • Extended service life compared to conventional spark plugs, reducing maintenance intervals
  • Designed specifically for powersports engines where heat range and electrode design are critical

The XS4163 is a direct OEM-style replacement that helps restore engine efficiency, improve fuel combustion, and maintain peak power output. It is an ideal upgrade or replacement for riders who demand dependable ignition performance on the trail, track, or water.

Quick.

Good prices and easy ordering process (order #18003). The only issue that I had was after placing the order, completing the entire process, I received three emails stating that "We noticed that you started checking out on our site, but didn't quite finish the process". After calling customer service, they ensured me that the order was complete. Since then, I receive the same email(3 emails at a time) on a daily basis. Just a little annoying, but easy enough to delete.

I needed to verify the part was correct. The telephone staff was very helpful, professional and informed about your products.

Lowest pricing. very simple process from start to checkout. A+++

Good. Fast shipping
