Well i figured i would share my experience with these 2 intakes. First off i have been running a KN complete CAI since i bought the truck 3months ago. Tuned it with the HPtuner and wideband and got the AFR dialed in to 12.5/12.9. Well since i am going to be funding a new project i figured i would sell my intake to my cousin and just run the Gotts mod. Since everyone says its the same if not better mod for an intake. Well i put the stock intake w/ the gotts mod went out and did some scanning and i sh*t you not my wideband read almost 1.0 richer than it had before. So according to my wideband the Gotts mod does not bring in as much as the CAI intakes on the market today.

Im sure it can be debatable in everyday but i figured i would share my experience with it.

You forget area of MAF and location has all to do with a/f ratio and not "more air". You have a naturally aspirated motor, it brings in the same amount of air every time, it's not starved for air. The Gotts isn't mean to flow copious amounts of air. The stock intake can flow more than enough at 6000 rpm anyways, it's meant to relieve restriction. You also forget your filtration efficiency is sub 98% with the K&N, while stock is 99.5%+. I hope that 12.5 a/f is at WOT too, if you're running that at lower throttle position I'd love to see the buildup from running rich.

yes that is at WOT. Regardless of the MAF location when modifying the MAF table to dial in WOT afr your telling it that at this voltage so to say your bringing that much air in. Now not bring that much air in at that voltage would cause it to go rich am i correct?

otto457

Not when there is air that cannot be accounted for. If air is going over or around the MAF that it doesn't know about, you'll need less voltage to produce the same a/f ratio. The reason the stock MAF runs richer is because the tune before was accounting for that air going around by using the wideband even though the MAF didn't know it was there.

So really what your saying is the air going around/through the MAF is actually less. Hense why the wideband showing richer conditions. Yes i know i can fix this issue with tuning again im not a newb.

I think you misread into the tuning comment. I was saying why it was richer with the same tune, not that it couldn't be fixed. What it comes down to is there isn't "more" air coming in, just differences in the flow and MAF conditions. A CAI will flow more total CFM's but when only 381 CFMs can be used in a 5.4L at max output, it really doesn't matter as both will flow more than enough. There's a slight advantage to having that little less restriction, but IMO filtration is more important.
