R9K Tuned Coupons — Up to 20% OFF in August 2025

R9K Tuned began in 2006 with a young mechanical engineering student who was smitten with a certain rusty Toyota engine. Tuning became a key part of this tinkering, and R9K Tuned has become one of the best 2ZZ-GE tuners thanks to a lot of hard work and dyno testing. It wanted to develop a site where the community can come to locate the best components available for their engine, as well as bespoke parts available only through it, in order to aid the community even more and bring underutilized Toyota engines into the spotlight. Its goal is to take you to the next level and make a splash in the ever-changing import industry.
