Message:
I am looking into the K&N filter system for my truck. But the available cold air hoods look good as well. I have scanned the posts and have found no direct comparisons between the two in the area of performance gains. Does anyone have information in this area.

I'm thinking the shaker hood from proglass is said to give 17 extra horseys'...at least for the 4.7... i'm not sure but i think the FIPK's offer just about as much....
hope that helps..

The Cold Air Kits (K&N, Volant, Z-Tube, etc.) will give you the most gains due to the cooler air and less restrictive intake path. The Hoods are mainly for looks but do help a bit to reduce the temperature even more and will help out a little bit more on the HP production.

Really Bernd? I'd sure think that the shaker setup would deliver the coolest air with the least amount of resistance (compared to an underhood filter and an attached tube). The air comes right in the the shaker, through a K&N filter to the TB. No hoses ... no bends ... no twists ... no restriction.
Whatcha think?

i agree with you blizzard, the ram air kit would get the coldest air and ram it through the throttle body and into the engine. I have heard that on a camaro SS, speeds above 80mph the ram air hood acks like a mild supercharger.

I got a hood scoop which goes right into the 14X4 open element which sits right inside it. My only problem is that I gotta rotate the filter now and then cause it gets all dirty in front. Cost was a minimum. I think 50 for the filter and 35 for the scoop. That was 5 years ago though.

The boundry layer of air going over your vechile is between 1/16 to 1/4 inch depending on the location of the air measurement. The best place for the airintake is close to wear the hood and glass transitions. The Ram air effect does very little until your RPM's excede 5500-6000. You must also relize that the little bit of power you gain with this set up on a production vechile will probably not be enough to overcome the increase in drag it will cause. You can comput the cfm of air flow that your engine can use mathmaticaly. Once you reach this figure any additional flow capacity is just a wasted. Example: If I have an egine that can only utilize 750 CFM at it's max RPM puting a 1000 CFM carburator on it will not produce any more HP and it wmight hurt torque and responce.

Guys I apoligize. I mixed up some of my old cruise missle air intake files with my old hot rod files. They {hot rod)claim that your scope needs to be 1 1/4 to 1 1/2 inchs above the hood to be effective like the old dodges. I found a cheapy mod though. If you can tap into the cowl vent area buy the base of the wind shield you can get a mild ram air effect because there is a high presure area above this spot due to the hood and windshield transition.

And they wonder why I run a Cowl Induction Hood. ;)
Not only do the Cowl Hoods work, but it also reduced the underhood temp by 15 degrees (measured).
If you're going to be running a shaker/cowl/snorkel style hood, make sure that the filter is somewhat isolated from the underhood heat. (A K&N "Extreme" Lid wouldn't hurt either.) This ONLY applies to the folks using the old fashioned round filters ontop of the TB. For those with the intake tubes, we've got it easy...just remove the flap from the passenger-side/front next to the radiator and you'll be breating cooler air.

That's my plan, Bernd. Extreme filter-top is ordered and will be here by installation day. Should work pretty well.
