Bad measurements after SXTH Element cold air intake

[SXTHMark]

Good morning. Thank you for the additional insight. I just installed the cold air intake from you guys and my 2026 4runner Pro is throwing the Mass Airflow Senor issue which is throwing all other warnings. I checked the position and placement of the sensor and the connections on the tubes, but nothing is working and car is going into Limp mode. Please help and have Zach read my email please.

Hey there! I see you have a Pro model. Our intake requires a tune to properly run on the Pro because the OEM Pro intake system has a different MAF size and subsequent matching ECU programming. We mention this right under the "add to cart" button and I apologize if you missed this.

If you are not looking for tuning, please contact [email protected] or engage with your email with Zach to arrange a return and refund. We'll waive any fees. Sorry about that!

Thank you so much, I guess i was so excited I overlooked it. I want to keep the product, but want to not void the warranty on my new Pro with having it tuned. What do you suggest? Is it safe to have it tuned and is there a way from Toyota not knowing?

I highly recommend asking your service dept about any modifications you "might" make to the truck down the road. Some will be cool with tuning, some won't. The OEM ECU does not have a flash counter, and with that being said it would be difficult for them to know it's been flashed if it was flashed back to the OEM file.

Also keep in mind they cannot void you're entire 4Runner's warranty for ECU tune. They can only deny free warranty repair for just cause that the modification caused your problem visit. For example, if you are tuned and your shock explodes randomly, that shock would be covered under warranty even if you have an ECU tune.

Hope this helps!

thats a slippery slope with an ecu tune. they can blame anything remotely tied to the ecu to a lot of things engine related.

hardware outside of the engine or related to it is pretty easy to get around, but ecu is tied to way more stuff that is important than say shocks, wheels, body panels, etc.

once you are past the 3/36 window yeah go ahead (or if you have a vsa ext warranty window)

remember the dealer is the first line of defense, if they say a ecu tune is to blame even remotely, toyota usa will see it in the notes and just dismiss your claim right off the bat. then it will be upon yourself to prove it otherwise.

and i have seen it happen before, once it gets in your service records of your vin, its going to be an uphill battle.

not saying a proper ecu tune will ruin things but dealers and toyota will side on the easy way out. and a dealer will foam at the mouth to charge you regular labor rates outside of warranty.

anything on the entire powertrain
engine
props
transmission
axles
pumpkins
transfer case

any of that blows a seal
or grinds and you have a tune...you've deviated
from what toyota engineering has tested and checked off
regarding power curve and shift points and fail safes.

if something happens who's to say a bad tune or firmware hiccup
didn't wreck things ?
toyota isn't gonna be very interested in covering powertrain if it
busts and you have power, throttle curve, or transmission changes

want a somewhat or full SEMA rig ?
you need to pay to play, and that also means whatever extra maintenance
you might be signing up for.... that's on your own dime

Is it safe to assume that different rims with non stock offsets could void the warranty on the drivetrain?

its a stretch, but depending on the dealer, some will overlook it, others will push the issue. the ones that like to push the issue sometimes have an ulterior motive to push you out of warranty work and into standard labor rates where they make big money and they can start throwing everyting at the wall to see what sticks and doesnt (which in turn costs more time and parts)

i see this now in usaf maintenance, throw parts at something until it fixes it, you eventually replace the dead component(s)

just remember the dealer is the first line of defense for toyota. if they annotate it in the service records this or that, that is ammo for lawyers to say it could have been affected. then it fall back to you to prove it otherwise.

that why most people say to do mods after your 3/36 or 5/60 (or ext warranty window) to do some mods. once you are out that window you know you get around the warranty issue and just deal with the problem than trying to do the warranty dance with anyone.


as i have seen before (not related to vehicles), i have seen the OSI (usaf) go after a civilian and get him kicked out of civil service to make an example. they found a govt pen in his house and charged him with stealing govt equipment. yes its extreme and huge stretch, but technically it was govt property that was taken home (granted there was other issues with this guy) but that is what they went with since its labeled on the pen "property of the govt", you know those old black pens.

dont underestimate the ability to stretch something beyond common sense if it still technically within the law and fine print.

Wheel spacers and messing with offset puts strain on wheel bearings

Wheel spacers and messing with offset puts strain on wheel bearings

just putting on aftermarket wheels does that, if i remember correctly most 3rd party wheels dont even get close to toyota offsets.

the best i can find in a decent set (keyword being nice looking pattern) of wheels is 25 offset which is a far cry from 6th gen 43 minimum offset up to 62 offset on the pro/th trim.

but most dealers wont give you too much issue with being close to the oem offset.

i usually only add 3rd party wheels and keep the oem tire size to minimize most of that issue. over the years i went from being more risky to now being as least intrusive to modding a vehicle. i dont have time anymore to deal with vehicle issues. i have better things to spend my time on, like fishing, being lazy at home during the winters and going on road trips to see my mom or the grandson.

its funny how over the years my priorities have done a 180 to what they use to be.
