I noticed Stillen is offering a Hi-Flow Intake Kit. What you think is the HP gain with this kit. I am not interested in a exhaust kit, just looking for under the hood parts. Anyone has this kit installed or on another veh, what was the results?

 

One aftermarket computer reflash company ( a reputable one) has this to say. I have heard similar things on other forums.., the stock computer apparently adjusts to mods over time and nullifys much of the gain. Don't shoot the messenger here..

Not much to go on there, but interesting.

 

Generally, if we're talking intake kits they vary in range-most report a gain of 7-11HP but these are general numers, some produce much higher numbers when incorporated with Y-Pipe, Full Catback Exhausts and B-Pipe but then again most of that gain probably comes from the free flowing exhausts and Y-pipe rather than the Intake itself.

 

id say u would be lucky to get 5 actual whp........but hey it would make it sound nice....lol.....i say keep ur stock man....better to keep the oil nice and clean , get gain 5whp at the cost of dirtier oil............just my opinion

 

I don't see why you would get "dirtier oil" based on a cold air intake system.
