Product Details

The Bosch 9651 Double Iridium Spark Plug delivers exceptional performance and durability for demanding engine applications. Engineered with advanced iridium technology, this premium spark plug provides up to 4 times longer service life compared to standard copper spark plugs.

Key Features:

  • Ultra-fine wire iridium center electrode requires less voltage to fire, delivering exceptional ignitability and reliable starts
  • Laser-welded iridium tips on both center and ground electrodes (double iridium design) provide superior wear resistance and consistent performance
  • 360-degree continuous laser welding ensures maximum durability and heat transfer
  • Nickel-plated rolled threads prevent seizing and corrosion in the cylinder head
  • OE-quality construction meets or exceeds original equipment specifications
  • Improved fuel efficiency and reduced emissions through optimized combustion

The double iridium construction with laser-welded tips ensures exceptional electrode durability and maintains precise spark gap throughout the extended service life. The ultra-fine iridium center electrode concentrates voltage for a more powerful spark while requiring less electrical energy, resulting in better throttle response and smoother engine operation across all RPM ranges.

Good price

I found what I needed easy Thank you

It was very easy to shop for hope it fits my vehicle if it does I'll be very happy.

It was fine. I would rather have faster delivery but it worked out.

Exactly what I needed will be getting more in the future and telling other people about it

You guys were the cheapest so far and I have heard good things about you through respected forums.

good

I ordered a hitch off of this site for Christmas, I have never heard of it nor did I know how they were, but they are great! Got my package in I'd say 4 days, very fast and it was exactly what I wanted! Only down fall was they charged me 3 times and I was short 150$ for a few days. I got my money back and I would definitely order again.

Smooth transaction, very pleased

You guys are the only ones who had my part in stock. The shipping was quick and I was very happy with the condition of the bell housing that I ordered i would order from them again.
