Engine w/ Strakes, 2×2 Thin Plate (Part 4229)
Custom LEGO part image © 2025 Tom Alphin / Brick Architect.
Strakes are ridges that run the length of an object to manage aerodynamic forces.
"...based upon the original aircraft engine element (part 3745) from 1974: the smooth surface was cut with grooves, and connection possibilities were increased by a stud and socket at either end."¹

Ranking based on buying one copy of every LEGO set, counting the number of sets containing each part, then sorting by part and color.
Overall Rank is a weighted score combining the number of parts, sets, and colors produced.
Current ranking based on sets released between 2020-2024. (2025 not included because too few sets have been released and inventoried at this time.)
