With SEMA being so close, Fox Marketing provides the 2012 Honda Civic Si with a fancy widebody kit. The modifications include revised bumpers, tail spoiler, widened arches, vented bonnet, diffuser , and side skirts. Fox also painted the car BASF R-M Ultrasonic Blue Pearl.
The main focus of this build, as stated by Fox Marketing, was actually to showcase the performance capability and reliability from Hondas new K24Z7 power plant. The substantial performance upgrade is massive 450 hp due to the turbocharger kit. Taking into consideration the fact that the K24Z7 is already strong from the factory, a new Full-Race intercooled turbo kit was added. The turbo kit includes the BorgWarner EFR turbo, noticed before in Hondas LMP1/LMP2 engine program, and 2012 Indycar teams.
Additional power and durability also come from Honda RRC intake manifold (euro Accord Type-R). Because of such type of power, a serious traction was needed. That's why Fox chose a 10.5 inch wide Vossen wheel with Toyo Tyre. The other part of the kit includes sport suspension, chassis tuning, and brakes. As for interior upgrades, Honda Civic Si got Yonaka Ronin racing seats with matching upholstery and trims.
