2022+ WRX K450 Package

Kozmic Motorsports has spent extensive time testing the best performance parts on the market over countless hours on the dyno and thousands of street driven miles to bring you some of the best packages on the market. We have thoroughly tested these packages to be both safe and reliable for the every day daily driver, as well as making great power for the avid enthusiast. 

Please note ALL of these packages will require tuning with purchase, see the drop down menus on the product purchase pages to select tuning options.


Our Stage 3X Package - AKA: K450 is for the owners looking for peak performance in an OEM+ state of their WRX. This package takes the torque capabilities of the engine to what we consider the long term operational limit for extended use. We cover the basic upgrades to get a nice sound as well as adding our proprietary turbocharger upgrade to keep the top end power pulling well past OEM redline. If you already have modifications, we can complete your vehicle to the K450 Package with ease, just give us a call. When choosing the parts for our power packages many concerns come into play leading us to a select few options we offer.

  • Fitment - 100% OEM Fitment, no modification required. No rubbing or contacting other parts in the area, etc.

  • Manufacturing Quality and Warranty - Amazing part quality and manufacturing techniques, with outstanding warranties on the entire system.

Intake and Charge Air

One of the first mods to the car is opening up the intake tract before the turbocharger. The OEM air filter and air box assembly becomes a large restriction once you reach ~40hp over OEM output. With additional boost level over OEM, we work to keep the charge air coming out of the turbocharger as cool as possible by upgrading the Intercooler to the ETS Front Mount. Cool Air = Horsepower!

  • Important Note: Air Box - You will see it includes a comprehensive air box design that keep the radiant heat off of the intake filter as well as the heat coming directly from the radiator fans that can commonly cause a "bouncy" idle.

Exhaust is something many owners commonly look forward to with adding some "rumble" to the tone. Our K350 package offers 2 optional Exhausts - Invidia R400 Exhaust -or- ETS Catback Exhaust. Both feature 3" Stainless Mandrel Bent Tubing with TIG Welded Joints and Flanges. Either option can be paired with the ETS Gesi J-Pipe if desired. There are options to both of these exhaust systems, upon request we can offer other brands as well.

*Please note ETS J-Pipe can cause CEL during operation, for NO CEL do not replace*
