SCT was founded in 2003, born of the passion & expertise of a team that cut their teeth in performance shops, racing, vehicle calibration, performance parts manufacturing, and aftermarket tuning. From then on, SCT has devoted itself to the idea that engine tuning and calibration are a critical part of customization, and that enthusiasts should have the power to unlock the performance potential of their vehicles.

K&N Group of Lines;

For over 50 years, K&N® has been an industry-leader in automotive filtration and technology—offering products to increase performance, protection, and longevity in thousands of vehicle applications for consumers worldwide.

AEM developed one of the first Packaged Air Induction Systems. It's design came from their experience in dyno testing, understanding intake energy dynamics and racing at the Battle of the Imports. AEM’s presence in the tuner movement and its proximity to Nissan, TRD and Honda allowed them a unique opportunity. AEM's first air intake kit was offered for sale in 1994 as a "Do-It-Yourself" upgrade for the Honda CRX. This intake proved to be the beginning of a whole new tradition. People could suddenly purchase affordable cars and modify them for increased torque and horsepower. Today, the Company’s induction systems number in the hundreds. AEM is still the one to beat.

Airaid; We started with air filters, but our vision has grown broader. Pushing beyond the street, into new rugged frontiers, we are optimizing air intake across the entire spectrum of internal combustion. From powdery snow-slopes, sand dunes, mud bogs, drag strips and road trips; to finish lines everywhere, across every terrain, we power drivers and explorers to dream bigger, adventure further, and discover their full potential.

Since 1983 Spectre has designed and offered unique and innovative parts and components to fuel your car or truck obsession. Our products are designed and tested to perform and last.
