Re: Newby thread Highjacked - Lets talk about filters!
 

I added the K&N filter kit. Very happy with the fit, no problems. I was concerned about the "noise" that people have reported on here. No noise at all, very pleased. Does it "feel" faster, cannot say for sure, did not have the stock airbox on long enough to tell a difference.

One thing that IS different, it IS more responsive to throttle movement. :beerchug:

Now you got me wanting to dissassemble the whole thing and measure stuff.

By the way, ever 10 degrees drop in engine IAT = about 1 percent increase in power output. The best vehicles to put a cold air intake on were the older vehicles that had the breather horns under the hood. I made a huge cold air intake for a Scout one time and it made a huge difference on the trail when crawling. Before the cold air intake, it got hotter and hotter, even though I had a big custom four core radiator.

How'd you modify your intake to make it a true cold air intake? On our Denali, the intake also takes from the fenderwell. The plastic and foam, believe it or not, did not even line up correctly. I took it all apart, carved out the metal with a die grinder to match the plastic's opening making it much larger. I picked up almost a 1mpg increase in fuel economy. Pretty good for free fixin's!

The exhaust system on the H3 looks pretty clean. I'm not fond of the squashed area under the floorboard but it looks pretty smooth. I've often wondered how well the exhaust ports meet up with the header and if they could be opened up. There's no doubt that some improvements could be made, but at what cost?
