you could also look for a one piece Weber adapter, i had tons of problems with my two piece adapters, havent had any since i did the one piece swap.....
not to fuel the fire on the intake stuff. BUT. To reap the benefits from that intake it seems you would have to mod the intake in the head also, which also includes the exhaust...
The idea of a dual plane intake is not new. As a general rule, dual-plane intakes improve low-rpm response, torque production and idle quality. Smaller plenums favor power production lower in the rpm range. Dual plane designs generally feature runners of a smaller average cross-sectional area than a single-plane, creating higher flow velocity at low rpm. Simple physics.
physics? isnt this a damn 4x4 site lol
