The entire kit bolts on without any cutting or permanent modifications to the vehicle and includes all necessary brackets and hardware for a straightforward installation

Finally, KraftWerks says If you replace the restrictive stock exhaust manifold with a header, gains as high as 7 whp and 13 lb-ft of torque more have been found in addition to the claimed 164 whp.  We look forward to doing a full evaluation of this kit in the future.  Good Job KraftWerks!

NOTE: Compatible only with USDM, L15A engine and manual transmission.  

This carbon-fiber cowl fits in place of the small, plastic pop-out master cylinder inspection cover located just below the windshield where high-pressure air is trapped and diverted across the intercooler

Safety and reliability is further enhanced with an intercooler package. KraftWerks knew that their customers wanted an intercooler, but we also knew that they weren’t interested in ditching their fog lights or chopping up their front bumpers just to get a front-mount intercooler to fit. KraftWerks’ solution is a cowl mounted air-to-air intercooler system that mounts neatly under the hood in-between the throttle body and radiator.  The intercooler is fed cold air from a provided carbon fiber intercooler cowl. The cowl fits just below the windshield where high-pressure air is trapped and diverts cold airflow across the intercooler. The entire kit bolts on without any cutting or permanent modifications to the vehicle and includes provisions for both the intake air temperature sensor and the supercharger bypass valve.

The High-Boost Supercharger Kit includes a air-to-air intercooler that mounts neatly under the hood, in between the throttle body and radiator, and picks up airflow from the KraftWerks intercooler cowl.

The KraftWerks’ kit features the remarkable and innovative C15-60 traction drive Rotrex supercharger. The innovative traction drive is silent and effectively decouples the supercharger under light loads to minimize the impact on fuel economy.

The KraftWerks’ Honda Fit Supercharger Kit, features the remarkable and proven C15-60 Rotrex supercharger, Hondata engine management and a comprehensive intercooling solution. The KraftWerks Honda Fit kit provides has everything needed for a trouble-free, bolt-on installation

KraftWerks' Honda Fit High-Boost Supercharger Kit measures in at 163.7 whp and 132.2 lb-ft torque at 10 psi. The dyno sheet reveals horsepower and torque gains throughout the powerband

Here is the final whp chart from my L15A1 engine dyno run on a Mustang Dyno.

174whp @ 10 psi

Now the fun part; We did a little testing so on my 1st dyno runs we did it with the intercooler uncovered and hood opened also in 4th gear. The next run was done in 3rd gear and you can see that horsepower dropped from 173whp to 164whp, I believe this has to do with the speed compensation being used on the dyno software.

To me, the more important bit of information is that the horsepower dropped another 4% when the hood was closed, this means the intake is sucking in hot (less dense) air and can’t breath (flow) enough on the top end… and you can pretty much see it all along the boost curves (blue lines)."

174whp is about 210 CHP
