M-Series Super Fire Spark Plugs

HKS M-Series spark plugs are high performance Iridium plugs designed to provide improved ignition performance, durability and anti-carbon build-up.

  • 0.6mm Iridium Alloy Center Electrode
  • Outer Electrode with Platinum Chip
  • Short Type Outer Electrode (Anti-Vibration)
  • Thermal Edge
  • Spark Support Gap

M Series is recommended for reliable ignition, durability and anti-carbon buildup under high load.

The Iridium alloy is used because of its durability and reliability.  On an average plug, a narrow core typically shortens life span of plug but with the intense durability of iridium there is no sacrifice in any longevity.  With a high melting point of 2454 degrees C, opposed to the 1769 degrees C of white gold, the electrode can tolerate the high levels of compression and minor knocking without any deterioration. A nickel coating on the housing also prevents the spark plug from premature deterioration.  The Iridium plugs are available for multiple applications and offered in "colder" heat ranges of 7 and up and specifically for rotary, heat ranges of 9 and up are offered.

Heat Range: NGK # 10

An elegant workhorse!
Style: 10 Inch, Size: 150 Count (Pack of 1)
I hate washing dishes so I use these Dixie plates a lot and they are STURDY. They will carry a whole meal without wilting. The rim is deep enough that, should you be so inclined, you could eat ice cream out of them without any dripping or drooping worries. So something like spaghetti or lasagna would be easily handled. I now buy them 150 at a time because they're so handy and that way more economical. I use them instead of a cutting board sometimes. And they just feel the right weight, not too heavy, not too light. For a picnic or a walking-around party they would be the best for preventing spills. But what I enjoy is their versatility. You can even rinse them off and use them again if they've had light use. And the current pattern is cheerful too!!

Sturdy, Convenient Paper Plates That Hold Up Well
Style: 8.5 Inch, Size: 90 Count (Pack of 1)
These Dixie medium paper plates are perfect for everyday use. They’re strong enough to handle full meals without bending or leaking, even with heavier or saucy foods. The 8.5-inch size is just right not too big, not too small great for lunch, snacks, or light dinners. I also like that they hold up well in the microwave, which makes reheating easy and mess-free. Super convenient for busy days, gatherings, or when you just don’t feel like doing dishes. Reliable quality and very practical to keep on hand.

Dixie is the best and bestest price on Amazon!!
Style: 8.5 Inch, Size: 90 Count (Pack of 1)
Excellent made plates and they stand true to their description. Dixie plates hold up strong to your food . I find there are no leaks coming from the bottom , or soggy , sagging , collapsing cardboard like others. They hold up great in a microwave too. Load on the sauce or gravy and know that Dixie will take care of your food plate. The price is excellent on Amazon as well !! It’s an excellent buy for a fantastic paper plate!!!

Awesome Body Lotion For Dry Skin and Some Reduction Of Age Related Wrinkles
Scent: Sweet Vanilla & Soft Wood, Size: 18.5 Fl Oz (Pack of 1)
I have only been using this product for a short period of time, but I very much like the fragrance. The sweet vanilla and soft wood scent is a great combo and not overpowering. I like the texture of the lotion, which is a silky smooth clear gel and easy to apply. My age wrinkles are diminished and very much less pronounced. It makes my skin feel more supple, as I have dry skin and the lotion is perfect for that condition. It will definitely be my go to skin lotion going forward as I am very pleased with the cost and the improved skin condition is a very short period of time.
