today i was doing nothing at work, so we pulled out the OBD II and hooked it up, we gatherd the pcm info and had it displayed, at idle my Intake temp was about 43C (idling in a garage) we reved it up to about 3500 and held it there the intake temp went down to 41C (still idling just reving up)

So as the air sits in the intake it gets hot once you open up the tb and get the air moving, it speeds it up and cools it down, it doesnt have time to get hot..

I predict if i was moving (going about 65-70) with my CAI and Ram air hood, i have cold air being pushed ontop og the filter coming though my hood scoops, and i have air being rushed from the stock area.. as long as you keep the hot air from standing still it is cold air.. one day ill have to take the OBD II out for a spin with my truck and see if i can get some temps will moving. That would be pretty cool.

 

I believe the stock filter size is adequate when clean and no other mods. I like the fact that it takes air from outside the engine so as reported earlier, when its 75 outside and 200 under the hood you can access the cooler air. It seems to be agreed that what ever the temp of the air at the pickup point will remain fairly constant when traveling through the tube. I modified mine with just a larger opening to the airbox from outside, a higher flowing filter(plan for ugrades) and a smoother intake tube(airaid jr). It is only louder under WOT otherwise its nice and quiet. I did notice better throttle responce but without other mods don't expect much in mpg bonus. heres a photo, I know its a gen three but will work the same on gen two.

That looks like a really good system you have there.

 

I like the fact that you got rid of the stock resonator box. How much did that set up cost you? Doesn't seem to be too expensive.

 

HEY LOOK a COLD air intake!!!

 

I have a stupid question. Maybe more of an observation. In the winter don't we all have cold air intakes?

 

My set up cost around $140 total. $129 for the Airaid Jr setup(upper inlet tube and a higher flow filter), about $15 for a 4" 90 degree elbow and two 4" rubber couplers. I cut a larger hole in the lower airbox(about 4.75) to fit a coupler and the pipe and also opened up the fender whole to the same size. I cut off the ends of the elbow so they would slip into the couplers. I posted these under the gen three site but here ya go...

Here is a picture too of the old inlet pipe for comparison

so there isnt a filter at all? or is the stock replaced with a k & n

 

the stock filter is replaced withan airaid filter(comes as a kit with the tube for 129). I think K & N also makes an upper tube and a drop in filter for those that want to use K&N.

I didn't take any photos of the new filter as I did the lower box and fender work before I got the Airaid Jr kit. Its a nice filter though.
