K20 and K24 shirts and hoodies for the i-VTEC faithful.
Honda introduced the K-series in 2001 and it has been the default answer to almost every Honda build question since. The K20 spins to 8,600 rpm. The K24 trades ceiling for torque. Put a K20 head on a K24 block and you get the build that became its own category.
Our K-series designs start with the K20 head gasket: four 86mm bores, the coolant jacket routing, the fire rings. On a high-compression engine that lives above 7,000 rpm, the gasket is the part doing the quiet work.
Every piece is printed on premium ring-spun cotton or heavyweight brushed fleece, cut relaxed, sized S through 4XL. Original artwork, never AI-generated, never a stock template.
