Cold Air Intake Poll

Looking to get opinions regarding the following air intakes. Which would you rather have on your truck. Not looking for those that "don't believe."

Ran them both......
Sound..... Urd..... Its loud and sounds badass outside, but civil inside.

Ease of use, protection against elements.......afe

while n/a, the afe intake seemed loud inside the truck but I guess Thats subjective.



If it was raining with the urd, I would get water droplets sucked past the air filter and hit the maf sensor causing the truck to stumble.


Afe no issues.


Besides, at approx 40mph the stock, afe, and urd are drawing the same temps...... Ambient

 

Justus,
Thanks very much for the comments and you hit on my main concern with the URD, exposure to the elements. I was wondering what would happen if you plowed through large puddles of water or really massive rainstorms. Is the MAF sensor specific to the URD intake?

 

I just installed the aFe CAI on my 2014 DCLB. Instant power increase. You can't even tell its there until you put your foot in it then it rages. This is the only mod so far that I have done and its definitely worth it. Easy install, sounds great, looks clean, easy to maintain as well. Go aFe. they have been doing this stuff for awhile.

 

The urd intake uses the stock maf sensor.


Edit..... Now I see what ur asking.

The maf calibrator will allow further tuning and generally is set to lean out the stock mixture some, because the stock setup is rich (safe), and may cost up to 15hp so the claim is.

U do not NEED the maf calibrator to run any intake I know of.... It will just help get the most out of ur upgrades as possible.
I ran this also.... I didn't like the fact that I couldn't switch it off if I was running up a long grade in 100 degree weather..... I got pinging while running 91 octane.

I have since duplicated that run without the calibrator in the same heat with zero issues.

Will it make a difference u can feel?
I thought so, but I wasn't comfortable with the inability to a just on the fly or to turn on/off.

If u rlly want the best bang for ur buck, try to find someone with a supercharged tacoma, and go for a ride.

 

I run an Airaid on my Tundra and love it.

 

I installed the URD in my truck, with the concerns of weather, I also bought the filter "sock" from URD just to be on the safe side. I have used the sock ZERO times and had absolutely no issues. I love it and would not trade it for a thing (im told it works with the TRD S/C as well which is good news). The front grill, depending on which one you have, does a great job at keeping weather out. After living through the rainy season in southern AL and now KY/TN, I would not trade the URD intake. (Ive also had 2 friends get one after they saw and rode in my truck).

 

If it wasn't for the stumbling in the rain I'd def run the urd..... Sounded great, but it was a pita in rain when passing trucks or getting up to speed.
Maybe it was the poor sealing of the maf sensor where it seats into the bracket.... Most people have to install it like this.....

Connect maf sensor to harness.....seat maf sensor to the bracket on the intake tube......secure maf sensor safely/snugly while ignoring the crooked angle from the harness connector preventing proper seating causing stress and tell urself the plastic will not get brittle from heat cycles.

With my afe and stock intake I can safely snug down the maf sensor to the bracket on site intake tube and it sits flush. I can connect the maf sensor harness before or after tightening down the maf sensor to the intake.

OP just remember, u can't pull an colder air than ambient unless your running an ice box setup..... And again, stock pulls ambient at 40ish, but has some restrictions that can cost performance.

URD..... Benefit sound and low speed/idle intake temps (good if u like to brag about ur trucks idLe).
...cons...Carwashes, rain (grille type may be a factor), cutting sheet metal off the truck, much easier to hydrolock if u like to cross water just over ur bumper (remember the wake can come back after it hits the other bank and create a small wave which will now be higher than the actual depth of the crossing and possibly lock it up).

Afe benefit... No cutting, unaffected by carwashes, and rain, no hydrophobic sock or splash guard needed, same water crossing capabilities you had from stock, flush mounting for the maf sensor, run any grille u want, no fabrication or hunting down a smaller filter to use it with the supercharger if u choose to later.

Cons... I think it was louder inside the cabin than the urd but I'm not 100%.


I've gone back and forth..... 1st was the afe
Then the urd.....
Then stock......
Then afe again and I'm happy.


I'd run the urd right now if it wasn't for the maf sensor seating issue, and pulling water onto the maf sensor element. Nothing says holy crap like trying to merge and having the truck stumble. I cannot afford that now, Its nice to know I can call on 300+HP and not worry about stumbling.... I can handle throttle modulation just fine, I dont need to fight a computer at the same time.

AFE for me

 

Justin, great write up and no doubt that comes from experience. Sounds like I want AFE but I was not aware that the AFE could be used with the URD MAF Sensor (even though they sell both). I wonder if Gadget has ever looked at modifying so it could be turned off when not needed/wanted. Would that be easy mod from your perspective or not?

 

Ran the AFE pro dry on my 02 Cummins, never saw a dirtier turbo in my life, took it off and tossed it, after one oil change.

AFE pro Dry doesn't stop enough dirt.

 

Just installed the 50 series flow master dual exhaust and AFE cold air intake last night.

Truck rumbles when started, rumbles when I get on it, but is quiet when cruising.

I'm definitely satisfied with the combo

 

I was debating between these two too... but I have the rigid grill so Im not sure if the urd would be safe.

 

AFE still seems to be leading. Anyone else notice issues with the AFE Dry Pro filters allowing too much dirt/dust?

 

I'd pick the URD if I didn't have to cut a section off my truck. So I got a AFE stage 2 SI with a modded Volant air scoop attached to it. Love it The MAF calibrator is worth buying either with the URD or AFE The air scoop setup is for my TRD blower setup BTW

 

whats ur AFR at WOT with that force fed setup?

 

I would just run an aftermarket high flow filter, the stock airbox is short, direct, and close to a CAI.

 

actually, the 1grfe airbox has been run with zero filter media and gained zero HP on a dyno.

the problem is the intake itself

 

I have run them both too, along with an aFe dropin and a custom set up with a Volant scoop tied into the stock air box. Short story, I am running the URD and Cali, and will stay with it.

Performance wise, you will probably not notice much of anything. All gains are at the high end of the rpm scale, so unless you spend alot of time with your foot on the floor, only thing you will notice is noise. But note that I ran the urd and the afe cai against my Gtech perf meter and showed about a tenth in the quarter. My results though.... For day to day driving, never noticed any perf gains.

Noise wise the afe was noisiest. Now depending on what you want, this may be good or bad. For me the afe was bad as it had a kind of gurgling noise at around 1500 rpm. It was annoying to me as this is the rpm when driving around town. Ended up going back to stock due to that.

I then tried the urd. At first by itself without the cali and results were the same perf wise as the urd, not noticable unless on a perf meter. Noise was much better though, no annoying off idle gurgle.

After about 6 months, installed the cali too. To me this gave a noticable kick right around 3000-3500, when it goes into open loop, depending on throttle position. But I did notice it.

The urd cai and cali have been in for about 1.5 year and I plan to keep them on. I do not cross significant water and I did buy the shield, not the sock, sock will drop airflow. I have not had any stumbles and cutouts during rain storms, I am just off the Gulf Coast, so we do get good rainstorms. I also have a mesh grill.

Afe is easier to install, as the urd requires cutting the metal by the radiator, and also extending the maf sensor wiring (you need good soldering skills for this, sensor is sensitive). But for me, the afe off idle noise was a no go, happy with the urd setup.

 

If you run either, be sure to pick one of those filter socks to keep a much debris out as possible.

 

I'll let you know when I get the blower in Feb with my tax return

Don't forget the stock "cai" everyone claims on TW, the airbox sits on a hot engine block
