This is our 1JZ Center Cover, this cover clears the popular 1JZ and LQ9 coil-on-plug (coil-packs) it replaces the factory plastic cover and omits the rear heater hose cover portion. We created the perimeter from precision machined CNC 6061-T6 aluminum. Every portion is machined for a precision fit. The louvers are created from brushed stainless steel. The louvers can be adjusted to any angle of your preference, these provide superior ventilation to the spark plug valley between the the cams.
