What is black, agile and packs 400 HP at the crank? Give up.....? It's our STI. Thanks to the folks at Cobb Tuning in Fountain Valley, CA for their help with the SF intake, downpipe and the MAPS to unleash the full potential of the STI. 28% HP increase and 38% torque increase over stock is nothing to sneeze at. The STI is now crazy fast lots of fun.
