STILLEN Air Intake Box & Dyno Results for 2024 Tacoma

[MT-Taco]

i skimmed through this thread but this intake looks interesting. Anyone have any info or thoughts:


SxthElement

Looks similar? And it’s available now! The only thing I don’t like is the magnetic lid?? Not sure how it’ll hold up off road?

Mine has been shipped and will be here Thursday. Shall keep this thread updated.

I'm interested in your opinion. My only concern is that it would allow splashing water like in a huge rainstorm the ability to saturate the filter element. Looks like a straight shot right in to the element through the large opening. I would probably add a mesh door flap that extends down 4-5 inches to collect any water on it while still allowing the air to flow normally. I mean, it would certainly cause some turbulence, but imho, probably worth it. Hard to tell though without having one in my hands.

Sweet!

Per my 2024 Tacoma non hybrid I’ll share that I’ve been trying to run the trd pro air intake and I’ve experienced nothing but issues with the MAF sensor..
P010064 mass volume of air- too much
Lean bank 1 reduced engine power
Drive start malfunction
Traction control turns off
Secondary collision break system malfunction.

dtc will remain with the trd pro air intake can clear with gts+

As soon as you remove and reinstall the stock intake all this clears itself…

I’m curious now with a couple of these aftermarket air intakes per Stillen and HPS performance? Ive asked about this if customers have had any issue considering this has been problematic on my behalf and of course they’ve said they have had no issues….

I apologize if I wasn’t clear in my writing. The mass air flow sensor doesn’t measure measure air pressure drop, but the cooling effect air passing through the MAF/electrical resistance which is sent to the Denso Gen 4 ECU along with ambient air temp values to the same ECU, in conjunction with a differential pressure sensor, in the intake manifold-part #89481-WAA01 for the T24A-FTS engine, makes adjustment for air charge pressure/boost and fuel trim. If the rate of air flow in conjunction with air temp is out of value, then it could be recorded and logged. This is no different than estimating density altitude for aircraft, calculated before attempting take off from an airport at altitude with a prop plane. In 2012- VAG/Volkswagon Audi group Bosch MED9x ECU’s did not log power output, on their B8 chassis, but in 2013, with the Siemens “Simos” ECU, they did. Any automotive manufacturer will have some for of data logging for diagnostic events. When leased VAG “Siemens “sinks” ecu equipped vehicles get their oil changed at the dealer, the vehicle is getting plugged in to look for any anomalies, not necessarily for performance mods, but for unnoticed errors the vehicle is detecting. The data is sent directly to Germany to be evaluated.
the pressure drop on air charge is an issue between the inlet side of the intercooler and the outlet side. If engineered properly, a .5-2psi drop in pressure is normal. As air pressure decreases, air volume increases and vice versa. With the three sensors measuring air temp, barometric/intake manifold differential pressure sensor, and the mass air flow sensor-the ecu makes fuel trim adjustments and verifies the results with the upstream wide band oxygen sensor.

just posted to this thread looking to grab some feedback…..

IMO, ALL filters box whatever must use the stock MAF diameter so I'm not buying (pun intended) any massive changes. What if a box does not use the stock MAF diameter? simple the MAF reading is hosed which ain't good for power. One probably could just leave hood open, take off filer and prop the box up and too what the MAX HP any box filter whatever would do. Last point, any improvement to the induction of a turbo just saves a little HP to drive the turbine, the turbo will reach (in this application) desired boost and then open wastegate, the slight heat injected into the air stream via the slightly more HP needed to drive the compressor is wicked away by large intercooler. If one is not increase boost (regulated by ECU program) how is so much HP gained (about 6% to 8% HP per PSI of boost). Boosted is really a measurement of restriction in the air entering the engine, until I see a boost plot with all these magical boxes, I'll remain skeptical. Last point the ECU slowly learns boost, ignition, cam, and injection offsets, it is not surprising to change something and see a big jump in HP, only to have it turned away (a dyno is a no load one shot device). Pull the ecu fuse first dyno and between every run after so the ECU is running on base tune, last dyno run put the stock box back-on and lets us see what you really get. But then you could not run fancy boxes.

My Camaro has gone up 30% HP NA and I got the stock box, the Callaway Camaro runs the stock box with a hole cut in the bottom, my supercharged Miata ND runs the stock box, my Integra Type R runs the stock box (bores sleeved stroked B20 VTEC), heck I can't think of ANYTHING that I have that does not run the stock box if able (my Camaro has a built sleeved LT1 with FA supercharger on it no so stock box won't fit... but if it did I'd run it).

Last, I'm a little leery of gauzed oiled filters and dust / sand etc. I can't think of any factory or expensive tuner that uses them. I got a K&N filter with my Edelbrock Miata supercharger and just tossed it in the trash, thick paper is good for me, so what I lose a few HP (roots supercharger more sensitive to intake restriction).

Nutshell, not much there there IMO, TRD is red and that is always faster, so others are more open so you can have more turbo sound, all use stock MAF size, so other than a ever so slightly less restrictive filter albeit one that is iffy compared to a good thick paper one.. may free up a few HP needed to drive the compressor, which may help spool but since the boost is limited by programing, somebody better tell me how it is gaining HP.

Yes sir…..
