Who is Crawford Performance?
When you think of Subaru performance, you think of Crawford Performance. For years, we’ve set the standard in the industry, thanks to our factory-backed programs with Subaru of America and our unwavering commitment to quality. We design and manufacture high-quality performance components for every kind of driver, whether you’re tearing up the track, hitting the street, or exploring the backcountry. Our parts aren’t just replacements; they are significant upgrades designed to push your vehicle’s limits. We build components that deliver proven power, reliability, and the driving experience you’ve always wanted from your Subaru.
A Family-Owned Legacy Since 1993
At its heart, Crawford Performance is a small, family-owned business rooted in Southern California. Since 1993, our focus has been singular: designing and manufacturing high-quality performance parts for Subaru vehicles. This dedication earned us a distinction that no other aftermarket company can claim: we are the only one to have ever been officially supported by Subaru of America. That partnership wasn't just a sticker on a car; it was a deep collaboration built on a shared passion for engineering excellence. Our legacy was forged on the racetrack, where we've been testing, developing, and winning with our parts since 2002. This history isn't just something we're proud of—it's the foundation of every component we build.
From Founder Quirt Crawford to a Southern California Icon
The story of Crawford Performance begins with its founder, Quirt Crawford. Before dedicating his expertise to the Subaru platform, Quirt honed his skills working with major automotive players like Ford (Saleen) and Nissan. This extensive background in high-performance engineering provided the foundation for a company that would soon redefine the Subaru aftermarket. His vision came to life in spectacular fashion when he built the legendary cars for Ken Block’s Gymkhana 1 and 2 videos, showcasing Crawford's capabilities to a global audience. Perhaps his most significant contribution is the invention of the Air/Oil Separator, a critical component that effectively manages oil consumption in Boxer engines and has become a staple for enthusiasts worldwide.
Forged in Rally, Proven on the Track
Our story is deeply rooted in the mud and gravel of rally racing. Our collaboration with Subaru began in the early 2000s, a partnership that helped create some of the most iconic rally cars in the sport's history. This experience on the professional circuit shaped our approach to performance engineering. We took the lessons learned from the demanding world of rally and applied them to every part we build. The legendary Subaru STI became a dominant force in championships worldwide, and our contributions helped solidify that legacy, creating a benchmark for performance that we continue to meet and exceed.
The Only Aftermarket Company Officially Backed by Subaru of America
What truly sets Crawford Performance apart is a distinction no other company can claim: we are the only aftermarket parts manufacturer ever to be officially supported by Subaru of America. This isn't just a title; it's a testament to the trust and engineering integrity we've built over decades. When the manufacturer of your car gives a performance company its official backing, it means every component has been recognized for meeting an exceptional standard of quality and reliability. This unique relationship ensures our parts are designed to integrate seamlessly with your vehicle, delivering significant performance gains without compromising the reliability and character you expect from a Subaru.
This trust from Subaru wasn't just handed over; it was earned on the dirt tracks and asphalt of professional motorsports. Our history includes building engines for Ken Block’s iconic Gymkhana cars and developing factory-backed race programs that dominated the rally circuit. The lessons learned under the most extreme conditions directly inform the design of the performance parts we offer you today. Whether you're looking for Subaru WRX upgrades for spirited daily driving or rugged overlanding solutions for your Crosstrek, you’re installing components forged from a legacy of proven, top-tier performance.
The Engineering Behind Crawford Performance Parts
Every component we create is the result of meticulous design and rigorous testing. Our philosophy is simple: build parts that perform flawlessly under the most extreme conditions. This commitment to quality is why our performance parts are trusted by professional racers and dedicated enthusiasts alike. A prime example of our engineering in action is the record-breaking, Subaru-backed Crosstrek Desert Racer. This project showcases our ability to transform a stock vehicle into a competitive machine, proving that our engineering stands up to the toughest challenges, whether you're on the track or a remote trail.
Inventing the Air/Oil Separator (AOS)
Our reputation is built on innovation, and no product demonstrates this better than the Crawford Air/Oil Separator (AOS). We are widely recognized for inventing the AOS, a critical component designed to solve one of the most common issues in Boxer engines: oil consumption. Born from our extensive experience on the track and in the workshop, the AOS was created to properly manage oil blow-by, a problem that can compromise engine health and performance. This invention wasn't just about creating another part; it was about providing a definitive solution that has since become an industry standard for protecting these unique engines.
How the Crawford AOS Protects Your Boxer Engine
The Boxer engine's design can sometimes allow oil to enter the intake system, which is a problem for any performance-oriented build. This oil vapor mixes with the incoming air and fuel, effectively lowering your fuel's octane rating and increasing the risk of detonation. Our Air/Oil Separator intercepts this process. It separates the oil from the air and sends clean air into the intake while returning the collected oil back into the engine block where it belongs. This simple but effective mechanism is one of the most important performance parts you can install to safeguard your engine, ensure consistent power, and maintain long-term reliability.
Designed and Manufactured in the USA
We take immense pride in our commitment to American manufacturing. Every single one of our products is designed, produced, and packaged right here in the USA. This hands-on approach allows us to maintain strict quality control from start to finish, ensuring that every component leaving our facility meets the high standards we set for ourselves and that our customers expect. By keeping our operations local, we also have the opportunity to support other small businesses in our community. When you choose Crawford Performance, you’re not just getting a superior part; you’re investing in a product built with integrity and a dedication to quality.
The Ken Block Connection: Engineering Inspired by a Legend
Our history is intertwined with motorsport icon Ken Block. His groundbreaking work with Subaru redefined what was possible in a rally car and inspired an entire generation of drivers. We were fortunate to collaborate with him, contributing to the legendary vehicles that captured the world's attention. Ken’s partnership with Subaru and Vermont SportsCar produced some of the most famous builds in rally history, and his influence continues to guide our passion for innovation. This connection to a true legend is a core part of our story and a constant reminder to push the boundaries of performance.
Building the Original Gymkhana 1 & 2 Cars
Our work with Ken Block was hands-on; we were the builders behind the iconic cars in his first two Gymkhana videos. These weren't just rally cars—they were purpose-built machines designed to execute precision stunts that captivated millions. The intense demands of these builds led to a critical innovation: the Crawford Air/Oil Separator (AOS). We created this device to manage oil consumption in the hard-pushed Boxer engines of the Gymkhana cars, and it's now a cornerstone of our performance parts lineup. It’s a direct piece of motorsport history that you can install in your own Subaru, proving that the lessons we learned from the world's most famous builds are engineered into every component we offer.
What Defines a Crawford-Tuned Subaru?
A Crawford-tuned Subaru is more than just a car with a few aftermarket parts. It’s a complete system where every component works in harmony to deliver reliable, exhilarating performance. Our approach is built on a foundation of deep engineering knowledge, a legacy of motorsports success, and an unwavering commitment to quality. When you drive a vehicle tuned by us, you feel the difference in every corner and on every straightaway. It’s the result of a philosophy that balances raw power with control and durability, ensuring your car performs exceptionally without sacrificing its integrity.

Finally, we stand behind our work with a comprehensive warranty that gives you the confidence to push your Subaru to its limits, whether you're on the track, the trail, or the street.

Developed from our work on Ken Block’s original Gymkhana cars, this exhaust is engineered specifically for the 2002-2007 Subaru WRX and STI. It’s designed to deliver a raw, powerful sound and improve exhaust flow for a noticeable performance gain. This isn't just about making your car louder; it's about giving it the authentic voice of a rally champion.
