Thanks for your reply.
If you look at the picture above aproximately beside the battery but a good 6 inches below theres a black box. The stock fresh air duct fits partially in that black box. The diameter of that "tube" is Inch and a half or so.
I notice the short air ram product from K&N does NOT have provisions to adding a hose to that black box below. In the pic above theres a hose that is "t"ing off the mandrel bend of the injen. That rubber hose looks like its going to that black box.
I guess I should try to talk to some of my friends in the auto tech industry. I'm a mechanic by trade for 10 yrs. If you look at the diameter of the stock rubber tubing going to the stock airbox there isn't a dramatic difference to a mandrel bend of an after market intake system. IF you remove the fresh air duct from the bottom of the air box theres a 3" opening.
I bet if you just remove the stock air duct from the bottom of the airbox there wouldn't be a significant difference in CFM flow toa SRI system. The air temp of the "intake" air would be the same temp an SRI would see. The only real limitation would be the enclosed box 3" opening. Potentially more torque anc be seen by just removing the fresh air duct.
Perhaps this sound like a budget modification but the use of a stock paper filter media will not allow destructive sand to enter the engine. Longevity is the key. K&N style guaze filters are known to allow sand to get in the engine. This is proven by elevated levels of silicon in used oil anaysis. In other words SRI's and CAI's wear out engines.
