Cold air intake

Something like that was far more likely to benefit your old Ranger, that was time before they worried much about intake, exhaust, or computer controls. The current Tacoma system already flows more air than the engine can use so a filter that supplies even more is basically worthless.

 

Agreed, thats why ill just stick with stock on the taco. Might try that air accelerator thing for more noise, i miss that noise.

 

Not if you want more sound

 

Lots of misinformation floating around in this thread from those who know little about the physics of internal combustion engines.

There are many variables which can influence power an intake can “create”. Things such as: resonance, air turbulence, intake air temperature, velocity, length of the intake tube, taper of the intake tube, etc.

I’ve personally created and tested multiple custom intakes on the Honda S2000, witnessing highly variable results... yes I know this is a different car but similar physics still apply to normally aspirated engines. One example - a custom 4” long tube cold intake with aem dry flow filter and velocity stack, that tapers down to 3” before hitting the throttle body generated more than 12whp across roughly the top 50% of the power band when compared to stock. This is despite the same “popular” opinion floating around those forums that CAI do nothing to help with power... people still don’t get it. They apparently never will, and will continue lying to themselves and others.

The 3.5 in the Tacoma isn’t so different that it is immune to power gains from intake tuning. I’d bet money that there is power to be had. Intakes such as the Injen Evolution, which have a large intake opening, velocity stack, tapered tube, and additional inlet just above the radiator will almost surely free up some power by providing better throttle response and smoother, cooler airflow at a slightly greater manifold pressure than the stock setup. The gains will be even more amplified with a custom ECU tune (possibly even the prepackaged OV tune).

If I had time I’d do similar testing with my 2020. Unfortunately time is at a premium these days.

 

Please, s

Please show us the dyno charts that show hp gains from an aftermarket CAI on this truck....

 

You clearly didn’t read my post in its entirety. I haven’t, and likely won’t have time. Just providing a more informed response compared to most, based on real world experience. He said, she said, I realize. But that’s status quo for this thread.

 

It's not he said she said, there's dyno graphs floating around showing no gains from aftermarket CAI's om this truck....

 

I realize there are many “snake oil” intakes floating around for the taco and nearly every other car. Not refuting that at all. If you have the charts post them up. I personally don’t, and don’t care to look for them. Apparently you don’t either, which is fine.

However an intake which actually has encouraging properties over the stock design, such as the Injen Evo, likely frees up some power. Again... I don’t have charts to back this up, but I’m applying knowledge gained from intake tuning in other vehicles as evidence that there IS power to be had with most mass produced internal combustion engines. it simply requires manipulation of the right variables. If you don’t believe that, all good. You be you my friend.

 

I'm looking for them right now.....

 

I added a TRD CAI and cat back exhaust together. Floyd Hill on I-70 west of Denver is a 6.5 mile 6% grade. Before the intake/ exhaust I could not get over 65 mph in 6th gear (manual). On my first run after the intake/exhaust I hit 70 in 6th was still accelerating when I caught up to traffic. I had similar results on the approach to the Eisenhower tunnel, an 8 mile 7% grade. Watch the Ike Gauntlet videos from TFL truck).

 

Love it

Love it. Real world results. If your driving experience was improved, it was well worth the money. Can’t argue with that!

I too live in Denver and know exactly what you mean about the pains of tackling steep grades on i70.

 

The cherry on the sundae is the sound. Worth the price of admission alone.

 

Indeed, if you can find it for less than 40 bucks. I don’t like a loud vehicle, but I like to hear what the engines up to. This accomplished that.

 

Was watching a video of a guy installing this TRD unit on his truck. Being 30 minutes long you got a pretty good look at all the parts. The rubber inlet between the fender and filter box was different AND the resonator box that comes off the snorkel tube was WAY smaller. I wonder why that is? Is that the reason for the extra sound the TRD CAI makes?

 

I tried finding the thread where they test the different air filters/CAI's that showed no gains, but I haven't been successful.

 

I remember the thread too, he tested Stock, Aftermarket, and even no filter at all and all 3 were within less than 1 HP. It seemed obvious that any differences were immediately compensated for by the ECU. My guess is that you would have to have something like OV Tune making adjustments to match an airflow difference to see any kind of gain.

 

OK good, I'm not going crazy.

 

This mysterious thread could very well be worthless either way. Hard to say without analyzing its contents. If “they” tested ONE aftermarket intake, it could have very well been one which was ill-engineered for the specific application. Further, “no filter” will always yield LESS power due to the variables I mentioned in my initial comment (velocity, resonance, manifold pressure and IAT).

That said, I agree wholeheartedly that a tune will greatly improve any gains seen by any intake. This is proven across many automotive and moto applications.

 

Sure is great that anyone can have their own options on what other people choose to buy and how to modify the vehicles they own.

you obviously don’t like K&N filters no matter what the problem is with it. “Gaping hole” or not. Even if they make kit to fully enclose the filter and allow air from factory hole to enter. The ambient air temperature could still be “hot” either way. And considering the factory hole gets it air from the wheel well which is directly next to the wheel and brake system (which generates heat) I doubt it makes a big difference pulling “hot” air from the “gaping holes”

I am sure the factory intake vents work just fine in supplying fresh air to the engine. But at what temps ? Half tempted to go hook up my scanner and pull intake temps and compare. But not really worth my time. The truck runs great.

 

My scangauge reads intake air temp. It generally runs 10 degrees Fahrenheit above ambient air temp per the thermometer on mirror. (With factory stock intake)
