Designed and manufactured by Harrop Engineering from cast aluminium, This LSA Lid is suited to  fit with the new H2650i LSA Supercharger or factory LSA 1900 Supercharger. This LSA Lid integrates seamlessly in the engine bay and provides superior airflow distribution to the rear cylinders over the standard LSA upper lid.   Our LSA Lid retains the factory mounting positions for IAT and MAP sensors and offers variable intercooler inlet options, including standard quick connect hose fittings, 1" hose fittings and AN16/DASH16 fittings for maximum flow performance. The LSA Lid can also be optioned with our upgraded intercooler core, that is 2.5x larger than the OEM HSV & ZL1 core for improved cooling efficiency and performance.  The Harrop Intercooler Core features high density fin, closed pitch tubes with billet end tanks to withstand higher boost pressures compared to the factory end tanks which are prone to collapsing under load.   Applications: Holden VF Commodore and HSV GEN-F Chevy SS
