Do I need to flush the system before installing this radiator?

Yes. Old coolant contains sediment and corrosion byproducts that will compromise your new radiator's efficiency. Flush the block and lines with distilled water, then fill with fresh coolant after installation.

Will this radiator work if I've upgraded to a larger turbo or supercharger?

Stock radiator capacity is designed for naturally aspirated power output. Forced induction builds generate significantly more heat — you'll need an upgraded core or secondary cooler to maintain safe temperatures under boost.

What hoses and clamps come with this?

Radiator assembly ships without hoses or clamps. Use your existing hoses if they're in good condition, or source new ones to match your factory connection sizes — most suppliers stock Integra-specific hose kits.
