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.

Fast paced romantasy you will not want to put down!
Format: Kindle
4.25 stars! I LOVED this book with similar vibes to Hush Hush, Fourth Wing, and The Serpent and the Wings of Night! It was fast paced with easy world building and will keep you turning the pages late into the night because you will not want to put it down!
Huntyr is a fierce bad@ss FMC trained to kill vampyres her entire life. She is sent on a mission to go to the academy and earn her spot into The Golden City. Upon arrival, she is forced to room with the delicious fallen angel, Wolf, who is the only one who knows about her assassin identity. The romance, the plot twists, the secrets revealed, the battles, and the tantalizing training scenes had me hooked! And that ending…. I’m holding my breath in need to know hell!
Read if you love:
🪽 Fae, Vampyres, Fallen Angels
🪽 Academy setting with magical trials
🪽 Forced proximity and slow burn
🪽 Rivals to lovers
🪽 Hidden identities and secrets
🪽 Tend your wounds

Excellent Rivals to Lovers!!
Format: Kindle
The tension and banter between Huntyr and Wold was delectable. I absolutely love the fallen angel and all of his flaws. Huntyr is amazing too being a badass FMC with some major trauma. The world building was great and I enjoyed the training aspect of the story. The writing was immersive and was in the story the whole time. The ending had quite a twist that I hadn’t anticipated and made my jaw DROP. Excellent job! I also loved the narration. Laura is one of my fave narrators!

Main Characters: Huntyr and Wolf
•
I couldn’t wait to read this book; there was so much hype about it! And there was no doubt why. I fell in love with the characters and the plot itself. This book is mainly plot driven more than friction driven but it’s easy to follow along with. The characters are fun, easily understood. The main setting is at an academy where both the main characters are going through trials and building strength for the final test, The Transcendent. There are fantastic side characters as well. I loved the camaraderie between Huntyr and her friends. But we don’t like Lanson. 😆
We do have some plot twists that come into play throughout the book. Secrets and betrayal to be seen. I did adore Wolf and Huntyr’s relationship. It was a classic slow burn trope. They didn’t hit it off fast, but in time their feelings grew. I loved their banter, so sexy. Wolf is your next book boyfriend; Huntyr is your next vampire assassin independent bad-a*s female. Themes include loyalty, trust, self-discovery, a true slow burn romance. Side note: book ends on a angsty cliffhanger!

“My heart bows to you and you only, Huntress.”
Format: Kindle
3.5 🌟
This book popped up in my KU recommended reading suggestions and the synopsis sounded like what I was in the mood for. I'm so glad I took a chance on it. I went into this knowing absolutely nothing about it and ended up really liking it. I love when this happens.
The main characters are likeable and I easily found myself rooting for them. There is a mystery element to each of their backstories that I enjoyed watching unfold and can't wait to get more of. Wolf, in particular, has me fixated. Love him.
I found this to be an entertaining, addictive read with a plot that moves along at a good pace. It reads so easily I found myself very reluctant to put it down. Lots of twists and turns and the angst is there. A good set up for the next book to come, for sure.
My issues with this book....the dialogue feels a bit juvenile at times and there is a repetitive over use of a particular word phrasing that I found myself giving the ole eye-roll to. There are, without a doubt, some pretty cliche moments that gave me a bit of the cringe. I think this could've certainly 100% benefited from more depth regarding the world building. Perhaps the world building was sacrificed to keep the pacing quick? Just a guess. Also, the lack of consistency of character for the FMC was really evident and so she feels quite illogical at times.
Overall, this was a fun and enjoyable read that hit the spot well enough for me. That ending certainly has me impatiently pining for book 2!

Interesting take on the genre
Format: Kindle
True rating: 3.25 ⭐️
I enjoyed the fresh take on the genre. The best way I could describe the setting and world is an apocalyptic dystopian version of Farie where vampires, fae, and angles struggle to survive in what is left of the world. It was definitely interesting throwing the academy/hunger games aspect into this world as well.
Even though I guessed the final reveal early on in the book, I kept hoping I was wrong, and it would take a surprising turn. While the "plot twists" were a bit predictable to me, I still enjoyed the ride this book took me on.
Another downfall for me was the plot holes in the world building... I.E. if society has fallen and the world is in the aftermath of war, how are there trains running around the world? Just to take young adults to the trials to get into the golden city? How is the train maintained, the tracks clear, etc?
However, I did enjoy the FMC & MMC and thought they were fleshed out nicely. I also enjoyed the side characters but wish some were developed more like Ashalin (sp?). I do find myself rooting for the MCs to succeed and find happiness together, which is obviously an important aspect for romantasy.
Overall, was this an earth-shattering, mind-bending, terrific piece of literature? No. But was it the worst thing I've read this year? Also, no. This book has, to me, the bones of a great read & just needs a bit more to push it from an alright book to a great book.
Overall ratings:
Plot- 3.5⭐️
World building 3⭐️
Spice 2.5 🌶🌶
Main characters 4 ⭐️
Supporting characters 3.5⭐️
