Lucky for me, my trip to Fuji International Speedway didn't just conclude after the HKS Premium Day. Thanks to that little "By Invitation Only" piece of plastic that was around my neck, I was amongst the privileged few who attended the HKS factory tour. However, no photography was allowed in the factory.
Formed in 1973 by Hiroyuki Hasegawa, HKS is headquartered in Fujinomiya, Shizuoka and is currently the largest aftermarket performance accessory manufacturer in Japan.
Since Hasegawa's breakthrough of turbocharger kits, boost controllers and turbo timers in 1974, HKS has been in the business of performance tuning and has maintained a respectable reputation when it comes to top notch quality. The company is ISO certified and complies with the quality control regulations and standards.
Here are some of the highlights and pointers worth noting about HKS products.
