Product Details

The Bosch 003-159-81-03 is an OE Fine Wire Double Iridium spark plug designed to deliver exceptional performance and extended service life. This premium spark plug features advanced iridium technology on both the center electrode and ground electrode, providing superior ignition performance and durability that lasts up to four times longer than standard copper spark plugs.

Key Features:

  • Double iridium construction with ultra-fine 0.6mm wire center electrode and iridium ground electrode inlay for maximum performance
  • 360-degree continuous laser welding ensures superior retention and durability of the iridium alloy
  • OE fine wire design requires up to 24% less voltage to ignite, reducing stress on ignition components
  • Copper core provides broader heat range to resist pre-ignition and fouling
  • Nickel-plated rolled threads offer anti-seize and corrosion protection
  • Pre-gapped at the factory for easy installation without adjustment
  • Ribbed insulator prevents flashover
  • 12mm thread size with 26.5mm reach and flat seat design

Engineered to meet or exceed OE specifications, this Bosch double iridium spark plug delivers optimal ignitability, improved fuel efficiency, and reduced emissions. The tapered ground electrode design ensures consistent spark performance throughout the plug's extended service life.

Good description of parts. Now to hope what I get fits.

Painless and good price. I'll B Back

Couldn't use paypal but other than that it was fine. Battery came with a broken top, packaging was not up to the std. of other Optima batteries I have ordered on line.

So far its good.

yes happy after a good customer serice helped with a price adjustment to my order. they did have good prices on most things, but it took some work to find the lowest price, so you do need to be a smart shopper.
