Cold air intake issue

Installed this rough country cold air intake and i seem to have acceleration problems after, sounds super loud when i try to get speed but lacks acceleration feels kinda forced. I made sure all claps are tight and no light have come up. Any recommendation or should i just go back to stock ?

 

I would just return to stock and leave it be. There's very little to no benefit to changing out an intake on these trucks.
Maf scaling was an issue back in my Subaru days. Could play an issue here possibly but not likely.
Double check you maf plug and make sure you didn't knock a vacuum line off anywhere.
Make sure there's no plastic covering left anywhere on or in the air filter.

That's all I can think of really.

 

Return the rough country and go back to stock or buy a tried and true (for Tacomas) CAI, from TRD, AFE or SandB. Rough country CAI is crap.

 

Take off the tent screen that is over the filter. Looks like cheap tent material. I think they call it a small particulate bag cover. It screws with the maf sensor.

 

My opinion may be a little blunt, but anything rough country is crap. *For Toyotas.

 

The filter wraps don't mess with anything, maybe just a little air restriction if that

 

I’m truly not being snarky when I ask: if it ran better stock, then is the aftermarket better?
I’d just return it. The Tacoma’s air inlet system is cold air and has more than enough flow.

 

The air intake resonator serves a couple of purposes. One of those purposes being to give an immediate supply of readily-available air to your engine on quick throttle position changes. That's to say going from no throttle to instantly wide open throttle...the air is readily available (already passed through the restrictive filter on the intake) and right into the engine's cylinders to provide immediate power for the driver.

That said - a lot of aftermarket intakes remove this resonator, are also less-restrictive, and suck in cold air. In the case of our v6 engine, the air is already coming from the fender (where it is cold), so there's no benefit there (in fact some aftermarket systems may actually suck in more hot air than the stock system). Whether the aftermarket filter is actually less restrictive, would take some measuring to figure out.

As for less restrictive, we'll give it the benefit of the doubt that it is less restrictive. The reason more air, quicker, results in more power is that the goal is to always mix the air/fuel at a ratio of 14.7:1 (this is called the stoichiometric ratio) and all modern engines have a variety of sensors that work together to achieve this air:fuel ratio. Even still, adding 3 horsepower at peak RPM doesn't always equate to a better driving experience (as mentioned above)...but it sure looks good on the product's packaging and/or the dyno that shows that hp increase.

All that said - there's one viable reason to get an aftermarket intake like the one you got. The noise. That's it. If you add that noise to the engine - even if horsepower decreased by 5...I'd be willing to bet that most people in a completely blind driving test would say the vehicle felt faster as the intake got louder.

 

I would agree with the above. While doing a CAI is seemingly a popular, cheap mod to do, I don't think you'd net any real noticeable differences in performance, mileage, etc unless you're doing a complete overhaul to the entire truck, like exhaust setup and all that stuff. I'm no expert nor am I claiming to be, just simply one man's opinion on the matter. If you can make a return easily and get your money back, I probably would and allocate those funds towards something else. Maintenance over mods, boys and girls.

 

From what I've been told a cold air intake on these stock tacomas do nothing but cause more intake noise, plus from past experience the oil in them can screwup your mfa sensor.

 

Who remembers the "deckplate mod" from the 1st gens? It made it louder which also made you feel like it was faster.

 

Deckplate mod is still a thing amongst the 1st gen Taco/3rd gen 4Runner community. I never did it, nor have I ever been interested in doing so. The only thing I've done was replace my intake tubing with an Airaid tube, so I basically got rid of the intake silencer. That's it. No changes in performance except it might be a little bit louder. I did it simply to clean up my engine bay a bit.

 

If I remember correctly, it was about the only thing on 1st gens that you could do for "slightly" more power, other than a supercharger. I have no idea if it actually made any more power, but for a few bucks, the noise alone was worth it.

That said, I wouldn't spend more than a few bucks for a similar noise on a 3rd gen.

 

You removed the OEM stock Cold Air Intake "CAI" that uses the same air filter as the V8 Tundra (!) and replaced it with a shrouded open air filter which will be louder all the time and is taking in "cold air" away from a heat source (radiator).

 

Then explain how the 3rd Gen Tacoma has an engineered Cold Air Intake closed air filter box system from the factory.

 

I installed the TRD CAI just 3 days ago on my 2023 OR and can say that yes it definitely does have some throaty sound in the higher rpm’s. I can also attest that it has improved my Tacoma’s performance slightly when getting onto the freeway. I am not a lead foot or anything but it does make some performance differences over the stock CAI

 

Nothing beats a good dose of mental hp.

 

Could be mental…I’ve been known for that lol…

 

It certainly looks good, nice setup and I agree! I have an AFE stage 2 CAI on my second gen along with a TRD exhaust. I have a 160lb ARB bumper and I still get 18 mpg city driving, and while I don’t drive with a lead foot I certainly don’t drive slow. I would say that I drive with some relative pep in my step as I enjoy the sound of my exhaust as well as CAI. Point being, I think they’re worth it and in my experience they can and do (pending on brand and setup) improve performance, both MPG and getty-on-up.

and when I finally go boosted, I’ll have two cherries on top of my sundae
