Okay okay for those of you who know me know that I have a K&N cai and was an "advocate" for them but recently it's been about 90* and I've noticed my IAT's are well above outside temp due to "heat soak" we're talking 90* outside and my tuner is reading 120 at the intake. My question to you guys is, will going with a gotts mod lower these temps and still keep the same power, not that a CAI adds any.. You get the idea ... Also looking for the absolute best drop in dry filter I can use. Thanks open to all suggestions!

 

The air travels from the outside of the engine bay into your filter way to fast for there to be a measurable difference with heat soak between the Fender Gotts mod w/ filter and an engine bay "style" CAI.

I know I'm going against the grain in the F150 forum world but there's just no Hp difference between the two. If all you were doing is measuring IAT's while sitting of course you'll see a Temp difference but if you're driving, (when it matters) your Modular isn't going to run worse and affect Hp.

If it were a completely closed in box with not fresh air then sure, it'll make a difference but it's not, so it doesn't.

If you don't believe me, call any of the Top Ford tuners in the country and ask them if they care about in bay or in fender CAI. They're likely to just laugh at you. Andersons, Alternative Auto and Livernois will all say the same thing, they don't care. Lidio in particular will probably laugh at you.

 

Well first I didn't claim anything about hp, so that is not only irrelevant to this discussion but no one will be "laughing" at me as I am well informed on the situation, I'm mainly asking gotts mod guys if they have lower IAT temps than a K&N I'm no rocket scientist but it seems there would be a noticeable difference between a gotts cai and a K&N due to the fact one is directed out the fender well via direct closed tubing and one is "sealed" yet open air through the engine bay and fender.

 

My reply wasn't intended to scold or try to make you feel any sort of way. The boards have went back and forth on this topic for years and it's a topic about as emotionally charged as Abortion.

I understand why you (and others) think the way you do about the incoming air but there's more to it than what kind of air we think should be here or there. it simply doesn't matter for these Modulars.

To put it simply, the air in the engine bay isn't stationary and the temps would be nearly identical while the engines are making Hp. I brought up Hp because that's the final result to the equation we're trying to talk about. Air temp is XXx on the inside makes xx Hp and Air Temps on the Outside make xx Hp.

 

I mean I've always had a hard time believing the ford engineers designed the intake where it wouldn't flow sufficient air to the engine. Like really, aren't they competing with the rest of the market? You don't think they'd let it roll out on the lots choked down at the fender for no reason..?

 

Tell me what your IAT's are while driving. I have use a modified gotts mod with a aftermarket are intake tube. My IAT's while idling in traffic are around 8-15* higher than ambient. While driving the drop to with in 1-2* of ambient air temps. Recently we have had 91-92 degree temps and the highest I have seen so far in IAT's are 104*.

 

I only did the Gotts with a drop in Filter because I knew there's not much to be gained in this area. I'm usually around +10* of ambient.

On another note; I think the Gotts is a better choice that open bay non baffled filters because it can help keep water out if you find your truck swimming. ..even if it's just prolonging the inevitable.

Perhaps I should let you in on something since you seem unaware. - The stock original factory intakes in our trucks are CAI's from the factory...They all are. If you don't have one, someone stole it or worse, - you forgot to put it back on.

 

You could always check out the volant cai, it uses a dry filter. And it's enclosed.
