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.

Luxury product at great price
Size: 16 Fl Oz (Pack of 1)
Lovely stuff - like all Cremo products, this one has a luxurious and expensive feel at a very reasonable price. Definitely a masculine fragrance, but subtle. Great lather and cleans beautifully with no residue. Highly recommended.

If you have sensitive skin and dont want premium prices, Cremo’s body wash is an excellent option A+
Scent: Palo Santo, Size: 16 Fl Oz (Pack of 1), Scent: Palo Santo, Size: 16 Fl Oz (Pack of 1)
Cremo’s body wash for men has become a staple in our household. The product exudes a luxurious feel, from the rich lather to the clean, long-lasting scent that genuinely resembles a more expensive fragrance.
This body wash possesses a pleasant aroma of cardamom, papyrus, and most notably, palo santo. It features a warm, woody, and spicy scent, which is one of my preferred fragrance notes. Notably, the scent is strong without being overpowering. Additionally, I appreciate the aesthetic appeal of the bottle. The exquisite and vintage-inspired packaging complements the fragrance effectively.
What truly sets Cremo’s body wash apart is its gentle nature. I have sensitive skin and this body wash does not cause dryness or irritation. In fact, it leaves my skin feeling soft and smooth, which is not always the case with other brands I have tried.
The affordability of Cremo’s body wash is a significant advantage. It offers a high-end feel and fragrance without incurring excessive costs, making it an easy choice for repeat purchases. If you or your family have sensitive skin or simply desire a pleasant scent without paying premium prices, Cremo’s body wash is an excellent option.
Highly Recommended. 5/5 Stars.
