Hey guys.I juz bought the 9th gen Honda Accord 2.0 VTI-L and i would like to know any performance upgrades that can be installed without voiding the warranty.I find the car underpowered with its 2.0 L engine which produces 155HP.The car struggles to achieve a desired speed quickly but i handles really well on the highway up to 200 km/h.Would like to know some performance upgrades which increases my hp a bit.I wouldnt wanna install a turbo as it would void my warranty and i dun wanna blow my new motor.
