Kraftwerks is pleased to introduce the newly redesigned supercharger system for the 2012-2015 Honda Civic Si. Centered around the highly efficient Rotrex C30-94 supercharger, the Kraftwerks 2012-2015 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 2012-2015 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.

Great fit & light weight
Size: Large, Color: Green, Size: Large, Color: Green
I was a little worried this wasn’t going to fit my husband. It looked huge. We ordered a size large, he’s typically a medium fit but he has a broad chest/ shoulders. I’m pleased to say that it was a great fit. I steamed it to release the wrinkles without any issues. Exactly as pictured, nice and light weight. Would definitely recommend.

It looks ok??
Size: XX-Large, Color: Black
This is not much of a jacket. It's relatively thin and doesn't block a breeze... That being said, the fit is accurate with the size chart. It's not very expensive, but feels like it should be about half this price

Great cosplay jacket
Size: Small, Color: Black, Size: Small, Color: Black
I bought a jacket similar to this about 4 years ago and I absolutely hated it. It was cheaply made and so shiny it could blind a nighttime driver. I needed another one because my son out grew the old one. I hated having to buy what I thought would be another cheap jacket but when it came in, I was shocked. Apparently, I bought from a different maker because this jacket was perfect. Well made. Easily ironed out the wrinkles. This turned out to be the perfect jacket for my son. He loved it. I really love it. Very happy with this purchase. Hopefully, I do not have to buy another one but if I do, it will be this brand. I have saved it in my list just in case I do need to order another. It is so nice. Extremely happy with my purchase.

Coat is very nice - - I didn't expect it to be as nice as it is!
Size: X-Large, Color: Black
This coat arrived promptly, and I am very pleased with it. Very wrinkled, but it ironed up real nice. My husband is usually in between a Size L and an XL. I ordered an L first and it was too tight, so I returned it and ordered an XL and it was too big, so I would say the sizing is spot-on. I was able to take up the sides enough that it now looks good on him. The fabric and construction seem sturdy. He is wearing it to an Edgar Allan Poe function, and I think he will look fabulous.
