Out of curiosity.... isn't the point of buying the CAI not just the filter your also buying the bigger tube for the intake so it can push more air through? And with a 91 tune push more power. So say a 2015-2017 a closed lid CAI with a bigger mm tube would lead to better performance? As well as not worrying about increased inlet Temps because it's not sucking in engine bay hot air? I'm trying to understand, I promise I'm not trying to be rude 😅 I really wanna know. Only vehicle I've modified the hell out of performance wise is a motorcycle.

I did an injen evolution closed cai with a tune. It looks much better than stock and with the tune made my butt dyno tingle. Makes a nice sound as well. Very happy with it. Temps seem fine. Just a street car for me.

Here in South Texas closed box is the way to go. IAT results are too high with open box.

I just placed a K&N panel filter in mine and called it a day. I didn’t want a tune for a CAI but I get it, it does look better with an open induction.

Air temp is one thing but the air volume counts as well. Bib filter and wider diameter pipe would allow more air for the engine and it would affect performance. I'm glad you're heading towards dyne again, I wonder what the new results would be.

I know this is an older video but for ppl wondering I went from a stock box with a drop in k&n filter to a jlt just like in the video. Without a custom tune the car picked up about 2/10ths at the track from a 12.21@119mph to a 12.06 @ 121mph. Only other thing that was changed was I did have to use a sct bdx handheld which has the option to use the stock box intake or jlt. So it wasn’t technically a custom tune just a generic tune from sct that accounts for the bigger diameter intake tube. The weather and da were actually better when I ran the 12.2 than when I went back 2 weeks later and ran the 12.0 with the intake.

Thanks for the transparency and humility

I went Ford Performance calibration tune with the larger throttle body and same intake as the gt350. Living in FL heat soak can be a big problem. I have the ram air hood that does help keep things a little more stable. The only issue with the hood is sometimes I can suck to much air in so my air fuel ratio can suffer as the tune doesn't account for it. It's usually only an issue on windy days. Once my warranty is up I'll get a better tune.

Love my jlt intake with sound tube delete

Thanks for information very useful and somewhat common sense.

I got to have the induction roar.

I was going to say those hear extractors are functional but then you corrected yourself. Like you said though they are small and I think Ford should've done better. At some point I will replace my hood I think to get better air flow. Maybe a GT 500 hood? Anyway, I used to think the increased air flow of the JLT would offset the increase in heat for making horsepower, but I'm not so sure anymore. I think for me i may just stick with a closed box but go with the one from Air Raid which has a clear lid so you can see the filter. Best of both worlds.

A buddy of mine has a GT350, and the open box seems better designed to seal against the trunk. I live in Texas where summers are much hotter, so I'm sticking with the closed box.

Love my open box K&n!! The whistle gets me every time 🥵

I have a 2022 shelby gt 500 I consulted ford performance on there opinion and they told me no after market is better than what it comes with.

Any reason why you didn't go with the Roush? Roush Stage 1 their intake comes with a tune.

Very well explain thanks mate

I just got a 2019 GT convertible and I'm just going to put a K & N filter in it.

Is there a big difference in sound?

I’am surprise that you didn’t give the Steeda closed air box with 120mm a chance.

I typically see about 3C warmer than ambient temp with the same intake on a 2015 GT PP1 with BAMA tune. I run the 93 Race tune since we get higher octane gas versus North America. Because I am in Germany and get to use the autobahn and wrap out the tach, it did make a difference at higher speeds. Sounds also is nice too. Great video brother. Keep up the excellent work. By the way, they make a waterproof sock that you can put on the filter that will ensure it does not suck in water.

Interesting topic

How is performance on this? I’m trying to decide between open and closed on my Raptor?

Nice!

So the MAF isn't keeping up eh ? Let it heat soak, then give it a blast with the air gun and watch how fast it drops on the dash. Also the vents on the hood isn't for heat, it's for high pressure relief at speed. Cheers.

Good video, and spot on.

I think he just lying you know that cold intake make that car run faster

First!

Because you like high IAT and wasting money
