from the research i've done and facts i've seen the sri is better in most cases putting out more power and better throttle repsonse. Everyone is like the cai is better for top end (which does shiet for a d-series) and its not that great for the money.


But if anyone is interested i have AEM CAI(used for 6 months and just reoiled the filter) with bypass NIB (never installed) :thumbup:
