The Assassin is the most technically advanced single stage plate ever designed. The CNC machined design integrates the nitrous and fuel discharge ports into the outer perimeter.

Which in turn solves the problems commonly found on single plane manifolds, particularly small and big block Fords.

Great book!
Format: Paperback
We read this story as a class read aloud after we read the first Sprinkles and the Unicorn book. They noticed similar characters, and loved the story line. They’re begging me to buy the whole series of this and all the other books! I can’t read them fast enough.

8yr old loves this book!
Format: Paperback
The storyline here is so fun. My 8yr old needs pictures to avoid feeling overwhelmed by word counts. This is a good balance that keeps her engaged. She's chosen to pick up the book to read without being prompted, which is a win.

My daughter likes it
Format: Paperback
I bought this book for my reluctant to read 3rd grader. She reads it without me having to tell her to read, and is now carrying it in her backpack to school.

Captured a reluctant readers attention
Format: Kindle
We downloaded this book this morning for the Kindle. My daughter is a reluctant chapter book reader, but she saw the cover and was hooked. She loves cats. She read the whole book independently in one sitting and then started rereading it! I think reading it on the Kindle helped because it gave her percentages of her progress and made her more motivated to finish it!
