Centered around the highly efficient Rotrex C30-94 supercharger, the Kraftwerks 2012 Honda Civic Si kit produces impressive results throughout the entire power band due to its patented traction drive technology. And, unlike any other forced induction system, the Kraftwerks supercharger system provides a linear power curve, torque on demand, cooler operating temperatures, and total driveability.

The 2012 Civic Si supercharger system provides instant throttle response and a progressive power curve that increases all the way to redline without the typical 'spiking' or 'surging' associated with turbochargers. This unique, more useable power curve results in reduced cylinder pressures, less strain on engine components, and increased reliability. Rotrex superchargers also operate much cooler when compared to turbochargers and other supercharger systems, which reduces the engine’s intake air temperature as well as its risk of detonation.

Rotrex superchargers are renowned for their compact size, high adiabatic efficiency, low vibration, and quiet operation. Their unique traction drive technology is what makes all of this possible, which, unlike other superchargers, transmits power through frictional forces between its rolling elements. Each Rotrex unit features its own self-contained oiling system that remains independent of the engine. Its dual-action oil pump supplies traction fluid to the supercharger while the supplied cooler ensures proper fluid temperatures at all times.

Like all Kraftwerks supercharger systems, the 2012 Civic Si supercharger system includes all the necessary brackets, and hardware for a simple bolt-on installation. This kit does NOT include fuel management.

Finally a waist that fits!
Size: 8, Color: Graywhite 4p
I have a skinny 9yo and we always have issues with pants, jeans, shorts, pyjamas etc. being too big in waist. I was absolutely stunned that these actually fit him without the need to be taken in!!! But there is still plenty of stretch for bigger bellies. The shorts are a little longer than what we're used to for pyjamas - they go down almost to the knees, but the kid likes it. Although he's 9, I ordered size 8 and they fit great. Will get another set!
