SXTH turbo inlet installed

jrdees916 · Monday at 4:35 PM

I finally after months of waiting received the turbo inlet from SXTH. Looks like a very easy install. I am interested in the size difference compared to the stock one. Looks very well made due to the hardened material that is used and hopefully they did their due diligence to ensure there is no leaks under boost.

Update after install:

Well, I finished the install today and it took about an hour. Actually pretty easy of an installation. The inlet from the intake is about 1.5 inches bigger and the outlet to the turbo is about 8th of an inch bigger. This isn’t my first turbo vehicle and I will say if not only more air can be pushed through but also the stability of that airflow is smoother there is something to be gained from it. Taking off the factory unit there is a big baffling chamber that most of the air goes to which changes the flow and disrupts what is going to the turbo. These are just my thoughts but overall easy installation and I will be making sure that SXTH did everything they could to prevent any boost leaks

I like SXTH stuff and have their CAI, but I think this mod is a snake oil lol.

What makes you say that? How about that catch can?

It's basically 90% snake oil and placebo.

SXTH makes clean hardware, but the claims about power gains on this platform are marketing hype. The bottleneck on the 2.4L turbo isn't the factory plastic inlet, it's the tiny stock compressor wheel. Bolting a 25% wider pipe right in front of that small compressor inlet is like attaching a wider funnel to a narrow straw. It does zero for actual mass airflow.

On top of that, our modern Toyota ECU are strictly torque-targeted. The ECU targets specific load numbers, so even if that pipe flowed marginally better, the computer just dials back the wastegate duty cycle to hit the exact same torque target.

The glowing reviews are just butt-dyno placebo from sound. The OEM pipe has resonators to quiet turbo noise; the SXTH pipe deletes them. People hear louder spool noises and convince themselves the truck is faster.

Plus, per their site (https://sxthelement.com/products/toyota-tacoma-4runner-landcruiser-turbo-inlet), it requires their intake or an aftermarket tube with a 77-78mm OD, so it won't even plug-and-play with the stock airbox.

If you want actual, measurable gains on these trucks, flash an OTT tune. I'm running Overland Tailor Tuning on my 4Runner and that delivers real power, better shift mapping, and legitimate throttle response by actually recalibrating the ECU tables.

Unless you're running an upgraded big turbo and pushing max CFM, save your $250. It's an expensive noise maker.

What Stage tune from OTT are you running?

While I do appreciate and respect everyone’s views I posted this just to show what route I was taking with my 4Runner. It’s fine if you disagree with what i am doing or parts I have installed, but this was the last piece to my puzzle as I have upgraded the turbo already and for me to get the max boost tune from OTT my installer wanted to wait for me to get this last piece installed. I currently have the OTT tune already.

In other words cancel my inlet order which is taking forever, keep my cplt intake and get it tuned is what I am understanding?

That's correct

OTT tune is about $650. If the tuner quote you higher, find someone else. Trust me, you WILL feel the difference immediately.

The tuner didn't say any stage, it's the only one for the new turbo engine, unlike previous gens. Any future updates from OTT, they will reprogrammed at no cost.

I am hoping someone from OTT will chime in here to make it absolutely clear how the tuning stages work. My understanding is that it’s aftermarket parts like these that get you beyond the first, Stage 0.

It’s okay man! Some of us actually get it!

You’re thinking about it like Cobb or the Euro/Subaru world, where stepping up "stages" requires specific bolt-on hardware like downpipes, intakes, and intercoolers.

OTT doesn't operate like that. They keep all emissions 100% intact, so there are no catless/hardware-dependent files anyway.

On our new 2.4L turbo platform, the standard performance tune is essentially Stage 1. It’s a full ECU and TCU recalibration dialed in to run safely on a bone-stock truck or one with basic mods like tires and an intake.

Bottom line, you don't need any aftermarket parts to run the full tune. It’s strictly software optimizing boost delivery, fueling, throttle sensitivity, and transmission shift logic.

Whatever you add to the tractor, it remains a tractor. This 2.4L gas tractor engine will stay the same, regardless of what intake you add to the engine.
On the other hand, a thin air filter may harm your engine due to dust getting through. If you need to gain horsepower, the only way is through an aftermarket tuner, using premium gas, etc.
These things are just gimmicks, in my opinion .
