Unlock serious performance from your 1999.5-2003 Ford 7.3L Powerstroke with the KC Turbos KC300x Gen 3 Stage 3 Turbo. Designed for higher horsepower builds, this drop-in turbocharger delivers increased airflow, stronger top-end power, and improved durability over stock and lower-stage upgrades. Whether you're running larger injectors or building a more aggressive setup, the KC300x Stage 3 is built to support your goals.

The Gen 3 KC300x features a fully redesigned compressor and turbine housing system inspired by modern turbocharger technology. A ported anti-surge compressor cover improves airflow and surge resistance, while the upgraded bearing housing supports larger thrust and journal bearings for enhanced reliability under high boost and heat conditions.

This turbo is equipped with a .91 A/R turbine housing and a 0.70 A/R compressor cover. It is important to note that A/R (Area/Radius ratio) is typically used to describe the turbine housing only, which controls exhaust flow and spool characteristics. In this case, the .91 A/R refers to the turbine housing, while the 0.70 A/R refers to the compressor cover, highlighting the updated intake-side design. This combination helps balance top-end power with improved airflow efficiency.

As a true drop-in turbo, the KC300x Gen 3 Stage 3 installs in place of the factory turbocharger without requiring major modifications, making it an excellent upgrade for performance-focused 7.3L owners looking for reliable power gains.

Easy Install - Looks like the Original
Size: For Ascent 19-26|Crosstrek 2.0L 18-22/2.5L 21-22
Both of these filters, cabin and engine are really easy to install at home with NO tools needed and at a fraction of the price that dealers charge. These filters are for a Subaru Impreza and look almost identical to the originals and fit perfectly. Cabin filter installation is by dropping the glove box - detach damper rod and unclip sides. Unclip filter cover behind glove box and remove/replace filter checking airflow direction is the same as the old filter. Reinsert glove box and push up to locate side clips. Re-affix damper rod and you're done. Engine filter is equally easy. Unclip air filter housing (not necessary to remove entirely) slide out old filter and insert new on in same orientation. Re-attach clips and done. Took me 10 minutes to change both filters. Longest part was emptying all the cr*p out of my glove box. Good quality filter, easy to install and saves time and money. I bought a second set for a Mazda CX-5 non turbo and quality was the same. Installation exactly the same as above for the Subaru

Never Pay Again. Easy and affordable for your health and the vehicle.
Size: For Sonata Gas 2015-2019
Way easier to replace than I thought. I’ve done a cabin filter before, but never the engine air filter. After this, I’ll never pay someone to do it again. I actually went into a store first, and the cabin filter alone was the same price as this set that includes both the cabin and engine filters. Since I needed both, this was a no-brainer. Install was quick and straightforward, even for someone who’s not a "car guy". I can’t speak scientifically on how well they filter, but they’re definitely better than the mouse-destroyed ones that were in this car before. Huge improvement. Highly recommend if you’re looking to save money and do it yourself. They fit well and seemed to be exactly what was needed and expected.

Quality air filters
Size: For Accord 2018-2022 1.5L
The Honda dealership quoted over $100 for parts alone. I purchased both filters for $25 and they where a perfect fit and easy to install without any tools.
