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.

☀️ Holy Grail SPF Mist! especially for makeup days 💦
Item Package Quantity: 1, Item Package Quantity: 1
If you hate the feeling of greasy sunscreen but still want serious protection, this is the glow-up you’ve been waiting for. I use this as the last step in my morning skincare and as a top-up over makeup throughout the day. It’s lightweight, non-greasy, and gives a dewy finish without looking oily, just a fresh, hydrated glow ✨
The mist is fine and even (no big droplets or weird stickiness), and it dries down fast. No white cast, no clogged pores, no breakouts. Just SPF 50+ that actually works with your makeup instead of wrecking it. I’ve even used it midday at Disneyland and didn’t burn once, and I’m someone who burns if I think too hard about sunshine 🥵
Helpful hint: Shake it well before spraying, and hold it about 6 inches from your face for a nice even mist. One pass usually does the trick, but I like to go back over my nose and cheeks for extra protection ☁️ It also doubles as a midday makeup refresher, especially when your foundation starts looking a little dry 🧴
I brought this with me on a full weekend trip to Disneyland and it absolutely earned its spot in my park bag 🎒 I was in the sun all day, both days, and didn’t burn at all, even with minimal shade and back-to-back rides 🎢 It layered like a dream over makeup, didn’t feel heavy, and made touch-ups fast and easy in between churros. This mist officially passed the Disneyland test. 🎡☀️💕

Good but heavy smell
Item Package Quantity: 1
I will keep using this bc it works and the sprayer is sooo nice but the smell is so overwhelming. It’s not a bad smell but it’s just so heavy. I’ll use this one but I don’t see myself repurchasing.

Good but confusing instructions
It is very glowy. After spraying this on my husband commented on why I was sweating so much 😹 I told him it’s my face mist spf. I have very dry and very sensitive skin and this has not broken me out (yet). I’ve used it for about a week now. I don’t know how much sun protection I’m really getting though. And reapplying it all through out the day, esp in the summer will lead to very very oily looking skin.
It’s also confusing because it says do not spray directly onto face. (?) I just hold my breath and close my eyes tightly before I put my mascara on and spray this. So far it’s been helpful with not making my make up look cakey. There is a smell but it’s not a bad smell, slightly fruity and the smell of spf. If you are sensitive to smells this might not be for you.

This makes your skin glow. Smells amazing. I’m older and in my 50s and it is great sun coverage and brightener. I will 100% keep using this.

So refreshing, you’ll forget it’s sunscreen.
This stuff is fantastic. I love the super fine mist and how easily the pump works. It is soo refreshing and smells like fresh coconut. Ot doesn’t sting or burn my sensitive eyes, and it leaves my skin feeling revitalized and moisturized, not sticky or tacky. It feels amazing when it’s hot outside and you need a quick refresh and it won’t disturb my makeup. Coola is becoming one of my favorite sunscreen brands.
