That's the same size as the stock tube, so probably not. A larger tube will require a tune. Surely, Steeda would state if you needed a tune with this intake if one was required.
stock intake I thought was 113m and the steeda is 114m.. I know thats not much, but I swapped it for straight intake tube and its carbon fiber, which just looks cool. Ill upgrade to bigger CAI down the road if I need.
The reason I asked is because steeda says I do, however its almost same size as stock. Ill probably do the pulley swap then retune next. Just didnt want to hurt anything till I do
