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.

Premium Quality Cabin Air Filter Replacement
Size: Accord 2018-22 1.5L Gas, Size: Accord 2018-22 1.5L Gas
I like that the cabin air filter has charcoal in it to which help absorb oder which adds functionality. The feel of this filter feels like a fabric is used which adds quality to it over the thin water ones out there in the market. The install was easy and fit right inside the filter location with ease. Even though this filter is a higher quality filter of OEM, it does not restrict any airflow whatsoever.

The Best Filter Jerry, The Best!
Size: 2" x 10" x 11"
I installed once and it seems to work like a charm. I probably need to go rinse it off since it's been months--but I no longer have Honda telling me I need to replace an air filter when I go get an oil change. They tried but I knew it wasn't mine. LOL. Easy to install, and extremely good quality. No gaps in filter area either.

Perfect fit for my fit
Size: 2" x 10" x 11"
Bought this for my Honda fit sport. Perfect fit for my fit. We shall see how it works out in the long run. I'm guessing every six months I'll wash it out, give it a light piling with the refresher kit I bought. The car doesn't get driven a lot during the year, so, doing it this way should be more than fine.

Premium, Reusable Cabin Filter – Worth It Long-Term
Size: 2" x 10" x 11"
I've been using the K&N Lifetime Washable Cabin Air Filter in my vehicle for several months, and here's my experience: Pros: Washable & Reusable: Eliminates the need for frequent replacements, saving money over time. Improved Airflow: Noticed a slight increase in airflow through the vents, enhancing cabin comfort. Odor Control: Effectively reduces musty smells, providing a fresher cabin environment. Cons: Initial Cost: Priced higher than disposable filters, but the long-term savings offset this. Cleaning Required: Needs periodic cleaning to maintain performance, which might be inconvenient for some users.
