There is a notable difference between an enclosed SRI and a longer CAI. A benefit of the CAI is the source of air it can reach isn't restricted by a hole. It also tends to be in a higher pressure zone. The longer tubes help straighten out air flow and improve velocity. You can also put on a larger filter with a CAI. I prefer the Z1 CAI over the Stillen personally. If you add the larger filters, that 5hp is more like 8-10 more with proper tuning.
